10 Things Every Parent Should Know After a CHD Diagnosis

 A congenital heart defect (CHD) diagnosis can feel overwhelming. Whether detected during pregnancy, right after birth, or later in childhood, it brings a wave of questions, fears, and unexpected decisions. While every child’s heart journey is unique, parents across the world share common concerns: What does this diagnosis mean? What should we expect? How can we help our child thrive?

This article breaks down 10 essential things every parent should know after receiving a CHD diagnosis, combining medical clarity with emotional guidance. By understanding what comes next, parents gain the confidence to navigate the journey with strength, hope, and preparation.

1. CHD Is More Common Than You Think — and Many Children Grow Up to Live Full Lives

CHD is the most common birth defect, affecting nearly 1% of babies worldwide. That means millions of children, teens, and adults today are living healthy, successful lives with repaired or managed CHD.

Modern treatments have dramatically improved outcomes:

• Many CHDs require only monitoring.
• Others need medication, catheter procedures, or surgery.
• Most children go on to attend school, play sports, and reach adulthood.

While the diagnosis is life-changing, it is not a life sentence. With early care and advancements in treatment, the majority of children with CHD grow into thriving adults.

2. Not All CHDs Are the Same — Understanding Your Child’s Specific Diagnosis Matters

“CHD” covers more than 35 different heart defects, ranging from very mild to extremely complex. That’s why two children with CHD can have completely different needs, treatments, and long-term outcomes.

Key questions to ask your cardiologist:

• Which type of CHD does my child have? (e.g., VSD, ASD, Tetralogy of Fallot, TGA, HLHS)  
• How severe is it?
• Does it affect oxygen levels, heart function, or blood flow?
• Is this a defect that improves over time, stays stable, or may need intervention?

Understanding the specific anatomy and physiology of the defect helps you make informed decisions and anticipate what’s next.

3. A Multidisciplinary Team Will Guide You — You’re Not Alone

CHD care is not handled by one doctor. After diagnosis, you’ll likely be supported by a team that may include:

• Pediatric cardiologists
• Cardiac surgeons
• Fetal cardiologists (if diagnosed prenatally)
• Neonatologists
• Genetic counselors
• Nurses and nutritionists
• Developmental specialists
• Social workers

This team works together to build a personalized care plan, explain treatment options, and support your family every step of the way.

Parents often find relief knowing that CHD centers follow proven guidelines and have decades of collective experience treating cases like their child’s.

4. Genetic Testing May Help Explain the Diagnosis

Many hospitals now recommend genetic testing after a CHD diagnosis because:

• Some heart defects are linked to chromosomal changes or genetic syndromes.
• Identifying a genetic cause can guide care, especially if other organs may be affected.
• It helps determine if future pregnancies carry any increased risk.

Genetic testing options include:

• Microarray testing
• Targeted gene panels
• Whole exome sequencing (WES) (especially useful in complex cases)

Parents shouldn’t fear genetic testing — it is simply an information-gathering tool that helps create the most complete picture of your child’s health.

5. Early Intervention and Monitoring Are Key to Protecting Your Child’s Health

Whether your child needs surgery or not, ongoing monitoring is essential. CHD care often includes:

• Regular echocardiograms
• Oxygen level checks
• Growth and nutrition monitoring
• Medication adjustments
• Neurodevelopmental evaluations

Early detection of changes — in heart rhythm, valve function, or oxygen levels — allows doctors to intervene quickly.

If your baby struggles with feeding or weight gain (common in CHD), pediatric nutrition support can make a major difference in growth and healing.

6. Surgery or Catheter Procedures Are Common — and Survival Rates Are Better Than Ever

Many CHDs require a procedure at some point. These may include:

• Open-heart surgery
• Catheter-based interventions (less invasive)
• Hybrid procedures combining both methods
• Staged surgeries for complex defects like HLHS

Advances in 2025 mean:

• Smaller incisions
• Less time on bypass
• More child-specific surgical planning using 3D imaging
• Better post-op care and pain management

Most parents are surprised to learn how quickly babies and children bounce back — often feeding, playing, and smiling again within days.

7. Your Child Will Need Long-Term Follow-Up — CHD Is a Lifelong Journey

Even if your child’s defect is repaired, CHD is rarely considered “cured.” Heart repairs may require:

• Monitoring
• Medications
• Occasional re-intervention
• Transition to adult congenital heart disease (ACHD) care

The good news?

Children who receive consistent follow-up typically enjoy better heart function, fewer complications, and a higher quality of life.

Parents should keep all cardiology appointments, even when their child feels perfectly healthy.

8. Neurodevelopmental and Emotional Support Are Just as Important as Medical Care

Children with CHD — especially those who undergo early surgery — may face challenges such as:

• Speech delays
• Motor or feeding difficulties
• Learning differences
• Attention or behavior concerns

This does not mean every child will experience these issues, but early support makes a big difference. Many CHD centers include:

• Occupational therapy
• Physiotherapy
• Speech therapy
• Developmental assessments

As children grow older, therapy, supportive schooling environments, and emotional guidance help them thrive academically and socially.

Parents should also care for their own well-being — stress, anxiety, and guilt are common after a diagnosis, but support groups and counseling can help.

9. Building a Support Network Will Improve Your Family’s Journey

Many families say the most unexpected — and invaluable — part of their CHD experience is the connection with other parents who understand the journey. Support networks provide:

• Emotional reassurance
• Practical tips
• Advocacy resources
• Financial guidance
• Hope

Helpful places to connect include:

• CHD nonprofit organizations
• Local hospital support groups
• Online CHD communities
• Parent mentor programs

Speaking with someone who “gets it” helps parents feel stronger, more prepared, and less alone.

10. You Are Your Child’s Best Advocate — and Knowledge Is Power

Parents play a powerful role in CHD care. Being an advocate means:

• Asking questions
• Seeking second opinions if needed
• Tracking symptoms and growth
• Keeping medical records
• Learning your child’s medications and procedures
• Staying informed about new developments in CHD care

By understanding your child’s condition, you become an essential partner on their healthcare team.

Questions to Ask Your Child’s Cardiologist

• What should I watch for at home?
• How often will my child need follow-up?
• Are there activity restrictions?
• What treatments or surgeries might be needed in the future?
• What signs would require urgent medical attention?

No question is too small — and no parent is expected to know everything right away.

Final Thoughts: You and Your Child Are Stronger Than You Think

A CHD diagnosis brings uncertainty, but it also brings community, expertise, and hope. The medical advances of the last decade — from better surgeries to improved screening and genetic understanding — mean children with CHD are surviving and thriving in record numbers.

Your journey may include hospital visits, procedures, and tough decisions, but it will also include resilience, milestones, and joy. With the right support, information, and care team, your child can grow, learn, play, and live a long, meaningful life.

What’s New in Congenital Heart Defects 2025: From Screening to Surgery

 Congenital heart defects (CHD) remain the most common birth defects worldwide, and 2025 is shaping up to be a year of steady, practice-changing refinement rather than a single blockbuster breakthrough. Progress has continued along several parallel tracks: smarter newborn screening, expanded prenatal/fetal therapies, faster and broader genetic diagnosis, less-invasive catheter options, and improved surgical planning through advanced imaging and 3D modeling. Together these advances are shifting care earlier (sometimes before birth), making procedures less invasive, and giving families clearer prognostic and genetic information. Below I summarize the most important developments clinicians, parents, and health system planners should know in 2025.

1. New clarity in newborn screening — simpler, better algorithms

Newborn pulse oximetry screening for critical CHD has been a public-health success story for years. In 2025 professional bodies updated and simplified screening recommendations and algorithms to improve uptake and reduce false positives. The American Academy of Pediatrics has endorsed a streamlined algorithm that emphasizes repeat, standardized oxygen-saturation checks and clearer action thresholds so babies who need urgent cardiology evaluation are identified faster. These revisions aim to harmonize practice across nurseries and lower the variability that previously produced missed cases or unnecessary transfers. (PubMed)

What this means on the ground: most well-baby nurseries will move toward a more uniform pulse-ox protocol, with earlier second checks when initial values are borderline and clearer triage steps for infants who fail screening. That should reduce delayed diagnoses while avoiding an excess of unneeded echocardiograms.

2. Prenatal detection and fetal cardiac interventions are maturing

Prenatal ultrasound and fetal echocardiography remain central to early CHD detection, but the most attention in 2025 is on when—and whether—to intervene before birth. Fetal cardiac interventions (for selected conditions such as evolving hypoplastic left heart syndrome, critical aortic stenosis, and pulmonary atresia with intact ventricular septum) have expanded in specialized centers. Techniques like fetal aortic or pulmonary valvuloplasty, atrial septoplasty, and stenting are increasingly reported in multicenter reviews and case series, and outcomes data are gradually accumulating to refine selection criteria. These interventions are still high-risk and limited to experienced fetal cardiac teams, but they offer potential to alter the natural history of disease in carefully chosen fetuses. (jucvm.com)

Takeaway: prenatal therapy is no longer purely experimental in a handful of centers; it’s an active, evolving field with clearer indications and outcome tracking — but decisions require multidisciplinary counseling about risks for both fetus and mother.

3. Genetic diagnosis moves from “possible” to “practical”

Genomic technologies—chromosomal microarray, targeted panels, and trio exome sequencing—have become faster, more affordable, and more integrated into CHD evaluation. In 2024–2025 many centers now routinely offer genetic testing for infants and children with CHD, particularly when extracardiac anomalies, developmental differences, or family history are present. Newer studies in diverse cohorts (including large single-country series) are refining which variants are actionable for prognosis, recurrence risk counseling, and referral for syndromic management. Broader availability of trio exome testing is helping identify de novo and inherited variants that inform not only cardiac care but surveillance for other organ-system issues. (Nature)

Clinical impact: faster genetic answers help families with recurrence counseling and permit early screening for associated problems (neurodevelopmental, renal, etc.), improving longitudinal care coordination.

4. Imaging, modelling, and simulation: 3D printing and virtual hearts go mainstream

High-resolution imaging (CT, MRI, advanced echo) paired with 3D printing and virtual reality models has shifted from novel to practical for complex CHD planning. Recent multicenter work and systematic reviews show that patient-specific 3D-printed models and interactive virtual reconstructions improve surgeon and interventionalist understanding of spatial relationships, reduce operative time in some procedures, and enhance family counseling by showing tangible models of the defect. Institutions increasingly use these models for preoperative rehearsal, device sizing, and trainee education. (PMC)

What to expect: large or complex referral centers will offer 3D model–assisted planning as part of standard preop workup for the most anatomically complex lesions; smaller centers may access centralized 3D printing services.

5. Catheter-based therapies keep expanding indications

The trend to treat more congenital lesions percutaneously rather than by open surgery continued in 2025. Advances include refinements in transcatheter pulmonary valve implantation, expanding experience with transcatheter valve therapies in older children and adults with repaired congenital lesions, and developing device options for atrioventricular valve repair in congenital anatomies. Device manufacturers and centers are working on smaller delivery systems and growth-accommodating valve designs — important for pediatric patients who will still grow. The overall direction is towards more staged, hybrid, and percutaneous approaches that reduce surgical morbidity and shorten recovery. (PMC)

Clinical note: while catheter approaches can avoid sternotomy and cardiopulmonary bypass, long-term durability, need for reintervention, and infection risk remain central considerations in device selection and follow-up.

6. Surgical technique: hybrid procedures and minimally invasive steps

On the surgical front, hybrid approaches—combining limited surgical exposure with catheter techniques in the catheterization lab—remain popular for certain neonates and complex anatomies. The goal is to use the least invasive approach to achieve physiological stability and defer larger operations until the child is bigger and stronger. Minimally invasive and robot-assisted techniques are being adopted selectively, mainly in older children and adults with CHD, but require specialized training and infrastructure.

7. Systems of care: multidisciplinary teams, telehealth, and outcomes tracking

2025 sees stronger emphasis on integrated CHD programs: fetal cardiology, genetics, neonatology, cardiac surgery, interventional cardiology, nursing, and neurodevelopmental follow-up working together from diagnosis through transition to adult care. Telehealth—accelerated during the pandemic—remains an important access tool, particularly for counseling after a prenatal diagnosis, postoperative check-ins, and coordination with regional centers. At the same time registries and multicenter collaborations are improving outcome tracking, which helps calibrate which innovations truly change long-term survival and quality of life.

Policy implication: health systems should invest in multidisciplinary pathways and remote-care infrastructure so families outside major centers can access expertise and follow-up.

8. Global equity and access: disparities persist, but pragmatic steps help

Most of the technical and diagnostic advances above are concentrated in high-resource settings. In low- and middle-income regions, barriers include limited access to fetal echo, genetic testing, catheterization labs, and intensive pediatric cardiac surgery. Nevertheless, scalable interventions—like standardized pulse oximetry screening and teleconsultation links with regional centers—represent high-value improvements that can be implemented broadly and save lives. International collaborations that provide training, remote mentoring, and low-cost diagnostic strategies continue to be vital to reduce global disparities.

9. What families should ask in 2025

If you or a loved one is facing a CHD diagnosis in 2025, these are practical questions to raise with the care team:

• Has newborn screening been done with the updated pulse-ox algorithm, and what were the exact saturation measurements and repeat results? (PubMed)

• If CHD was identified prenatally: does this center offer fetal intervention, and what are the realistic benefits and risks for this specific lesion? (jucvm.com)

• Has genetic testing been recommended? If so, which test (microarray, targeted panel, or trio exome), and how quickly will results be available? (MDPI)

• For complex anatomy: can the team show a 3D model or virtual reconstruction to explain the planned operations or interventions? (PMC)

10. The research horizon: what to watch next

Expect incremental but meaningful advances rather than single dramatic breakthroughs: better growth-friendly valve technologies, improved patient-specific devices, more robust fetal-intervention outcome data, and deeper genotype–phenotype maps that help predict neurodevelopmental risk. Implementation science—making sure proven, high-value practices (like standardized newborn screening and genetic testing where indicated) are actually adopted—will be just as important as device innovation for improving public health impact.

In 2025 the field of congenital heart defects is defined by practical integration: screening algorithms are being standardized to catch critical disease early; fetal interventions are evolving into an organized subspecialty with clearer indications; genetic testing is moving into routine clinical practice for many affected children; 3D imaging and modeling are improving surgical planning; and catheter-based therapies are expanding what can be done without open surgery. The cumulative effect is earlier diagnosis, more personalized counseling, and a steady push toward less invasive care—provided systems invest in multidisciplinary teams and equitable access. For families, the message is cautiously optimistic: there are more tools than ever to diagnose, plan, and treat CHD — but choices remain complex and should be made with experienced, coordinated teams.

Understanding Acyanotic Congenital Heart Defects: A Comprehensive Exploration

Congenital heart defects (CHDs) are structural abnormalities present at birth, affecting the normal functioning of the heart. Acyanotic congenital heart defects represent a subset of these conditions, characterized by the absence of bluish discoloration (cyanosis) in the skin, indicating sufficient oxygen levels in the blood. This article delves into the intricate world of acyanotic CHDs, exploring their types, causes, diagnosis, and potential treatment options.

I. Definition and Types of Acyanotic Congenital Heart Defects:

Acyanotic congenital heart defects are characterized by abnormal blood flow patterns that, unlike cyanotic defects, do not lead to low oxygen levels in the bloodstream. The two primary types of acyanotic CHDs are:

A. Left-to-Right Shunts:

1. Atrial Septal Defect (ASD): A hole in the septum (wall) between the two upper chambers (atria) of the heart, allowing oxygenated blood from the left atrium to mix with deoxygenated blood in the right atrium.
2. Ventricular Septal Defect (VSD): Similar to ASD, but the hole is located in the septum between the two lower chambers (ventricles), allowing blood to flow from the left ventricle to the right.

B. Obstructive Lesions:

1. Coarctation of the Aorta: Narrowing of the aorta, the main artery carrying oxygenated blood from the heart, restricting blood flow to the lower part of the body.
2. Aortic Stenosis: Narrowing of the aortic valve, hindering the flow of blood from the left ventricle into the aorta.

Navigating the Complex Landscape of Congenital Heart Defects: Understanding, Challenges, and Hope

Congenital heart defects (CHDs) stand as a multifaceted challenge within the realm of medical conditions, affecting individuals from birth and demanding a nuanced understanding of both their complexity and the hope for effective interventions. In this comprehensive exploration, we delve into the intricate world of congenital heart defects, examining their nature, causes, impact, and the strides made in diagnosis and treatment. As we unravel the layers of this condition, we also shed light on the resilience of those affected and the ongoing efforts to enhance the lives of individuals living with congenital heart defects.

I. Understanding Congenital Heart Defects:

A. Definition and Scope:

Congenital heart defects refer to structural abnormalities in the heart that are present at birth. These defects can affect the heart's walls, valves, arteries, or veins, disrupting the normal flow of blood. CHDs vary widely in severity, from simple defects that may never cause symptoms to complex conditions that require immediate medical intervention.

B. Types of Congenital Heart Defects:

Septal Defects: These involve holes in the heart's walls, leading to abnormal blood flow between its chambers. A common example is atrial septal defect (ASD) or ventricular septal defect (VSD).

Valvular Defects: Conditions like stenosis (narrowing) or regurgitation (leaking) of heart valves can impede blood flow and strain the heart's function.

Cyanotic Defects: These defects cause a shortage of oxygen in the blood, leading to a bluish tint in the skin and lips. Tetralogy of Fallot is a notable example.

Obstructive Defects: Conditions such as coarctation of the aorta or pulmonary stenosis create obstacles to blood flow, requiring the heart to work harder.

C. Causes of Congenital Heart Defects:

While the exact causes of CHDs often remain unknown, a combination of genetic and environmental factors contributes to their development. Genetic mutations, maternal illnesses or medications during pregnancy, and exposure to certain environmental factors may increase the risk of CHDs.

II. Diagnosis and Screening:

A. Prenatal Screening:

Advancements in medical technology have enabled the detection of congenital heart defects during pregnancy. Fetal echocardiography, a specialized ultrasound, allows healthcare professionals to assess the structure and function of the fetal heart, aiding in early diagnosis and intervention.

B. Postnatal Diagnosis:

Some congenital heart defects are diagnosed soon after birth through physical exams and observations of the newborn's color, breathing patterns, and overall health. Further diagnostic tools, such as echocardiography, electrocardiography (ECG or EKG), and imaging studies like magnetic resonance imaging (MRI), help healthcare providers assess the severity and type of CHD.

III. Challenges and Impact:

A. Medical Complexity:

The medical complexity of congenital heart defects can vary widely, with some cases requiring immediate intervention, while others may not surface until later in life. The intricate nature of these conditions demands a multidisciplinary approach, involving pediatric cardiologists, cardiothoracic surgeons, and other specialists.

PDA (Patent Ductus Arteriosus) - A Parents' Guide For Premature Babies

As a parent in the NICU I lost count of how many times I got the PDA demonstration. I think most nurses love to demonstrate their medical knowledge and the PDA is something that they all feel they know something about. Out comes the giant picture of the blue and red heart and then comes the spiel. I heard it enough times that I should know it verbatim. Unfortunately every version was different, so without further research I would have been left confused. I often noticed other couples getting the cot-side impromptu presentation nodding along furiously then looking bemusedly at each other when the nurse disappeared.

PDA stands for Patent Ductus Arteriosus. Patent in this sense means "open", not "shiny" as in patent leather shoes. So, the Ductus Arteriosus is open, it should be closed.

What is the Ductus Arteriosus?

Pre-birth we all live in water, amniotic fluid. There's an argument that even after birth we all live in water, only we carry our ocean around with us. The word "amniotic" comes from the Ancient Greek word for bowl. So, as we live our pre-birth goldfish like existence in our bowl of water, how do we breathe? Well, our mothers do our breathing for us. Oxygenated blood is passed through the placenta from the mother to the fetus, thus leaving the fetus' lungs alone to concentrate on developing. That is why they are the last of the organs to develop before birth. This is also why so many premature babies have breathing difficulties and are constantly monitored for oxygen saturation. It is very difficult for the premature baby to maintain suitable oxygen saturation in her own blood using her own undeveloped lungs. To compensate for this, the baby is given an air supply with more concentrated oxygen levels than normal air (which is around 21% oxygen, the rest being mostly nitrogen).

So, what does the DA do? Well, when it is "patent" (ie "open") it allows the blood to flow through the heart without going through the lungs. There's no point pushing the blood through the lungs when they are immature and fluid-filled, they can not yet oxygenate the blood. In a full-term birth, the duct will close itself off anywhere from a few hours after birth to a few weeks. It does this by becoming more fibrous and eventually sealing itself off.

What does this mean for a Premmie?

In most preterm births the PDA will remain. The amount it is open is normally described in millimeters and can be anything from less than half a millimeter open to a few millimeters open. Normally, a PDA is evident to the doctor listening through a stethoscope as a background murmuring like a motorbike. An echo-cardiogram will almost certainly be performed to measure how open the duct is. This is a simple non-invasive test, just like an ultrasound.

After the test, the doctors will determine a course of action to close the DA if required. Well, that's if you're in a NICU which has a philosophy of closing PDAs. Like many matters in the NICU, there will be a philosophy in that Unit which is unique to that unit. Some will try to close the PDA with gusto, others will decide if the PDA is "hematologically significant" and take action based on that. That means, they will decide if the DA being open is a problem or not.

Treatment will either be pharmaceutical or surgical. The surgery is relatively uncomplicated. They will "ligate" the PDA, ie tie it off. Normally they will opt for a pharmaceutical approach to begin with. Commonly, a course of indomethacin is prescribed. The indomethacin is normally given as a course, the frequency and strength of which again will vary from NICU to NICU. Why this would vary is not clear to me. Surely some consensus of medical best practice has been reached and adopted by all clinicians? Not so, unfortunately. This variability is a recurring theme for most most decisions concerning premature babies. All I can suggest is that you research thoroughly, arm yourself with as much knowledge as you can and not be afraid to ask questions in the NICU. There really is no such thing as a stupid question.

In some countries a more successful drug for closing the PDA has been Ibuprofen, which is commonly taken for headaches. This isn't approved for use in all countries yet though, so may or may not be offered depending on your location.

Hopefully, the first course of drugs will close the PDA or at least reduce it to a size that is no longer significant. If not, another course of indomethacin may be prescribed. From memory, it has around a 30% efficacy so two courses will make it more likely than not that the DA will be closed but it is still reasonably possible that it won't be. There's a limit to how many courses of indomethacin will be administered. Two in our case, but again this will depend on the dosage used, which is variable unit to unit. Hopefully by this point the DA will now be significantly smaller. If not, surgery will probably be necessary. This surgery is a lot less invasive than it used to be.

General Information About Congenital Anomalies

Congenital anomaly is a mental or physical abnormality that is present at, and usually before, birth. Some anomalies may be medically insignificant and may not appear for some time. In other cases, the anomaly may pose a direct threat to life and requires immediate attention. There are, however, some anomalies that cannot be treated.

Question: What are examples of congenital anomalies?

Congenital anomalies include bone disorders, cataract, cleft palate, cretinism, Down's syndrome, congenital heart disease, hemophilia, joint disorders, pyloric stenosis, and spina bifida. Blindness, deafness, hydrocephalus, and jaundice are also often due to congenital anomalies, although in other cases they are the result of event that occurred after birth.

Limbs or organs may be malformed, duplicated, or entirely absent. Organs may fail to move to the correct place, as in cryptorchidism; fail to open correctly as in imperforate anus; or fail to close at the correct time, as in patent ductus arteriosus. Congenital anomalies often occur together. For example, 33 percent of babies born with Down's syndrome also have heart disease.

Question: What may cause the development of congenital anomalies?

They arise from the faulty development of a fetus, caused either by genetic disorders or other factors. Some anomalies arise from a combination of factors, and the underlying cause is far from clear in all cases.

Question: How are genetic disorders responsible for congenital anomalies?

Inherited congenital anomalies generally result from the presence of abnormal genes or chromosomes. Heredity is determined by corresponding pairs of genes, called alleles. One of these paired genes is dominant and the other recessive, and it is the dominant gene that governs the transmitted trait or characteristic. Thus, if the abnormal gene of a pair is dominant, the abnormal or anomalous trait will be conveyed to the embryo. If the abnormal gene is recessive, then both genes in the pair have to be abnormal for a congenital anomaly to occur.

Some congenital anomalies, such as hemophilia, are linked to a defect of one of the sex chromosomes. Many genetic disorders, however, are neither wholly dominant, recessive, nor sex-linked, but may be caused by more than one abnormal pair of genes.

Question: What other factors may cause congenital anomalies?

Infection in the mother is a common cause of abnormality in a baby. For example, an attack of rubella during the first three months of pregnanacy may cause her child to be born deaf or have cataracts, heart disease, jaundice, or other anomalies. Cytomegalovirus (CMV) and toxoplasmosis also cause congenital anomalies.

Certain drugs taken by a woman during pregnancy are often responsible for abnormalities in the child. For example, large doses of corticosteroids can cause a variety of congenital defects, as can some anticonvulsants given to control epilepsy. Other drugs include anticancer drugs; narcotics and sedatives; tranquilizers and antidepressants; antibacterials, especially tetracycline; anticoagulants; drugs prescribed to treat cardiac conditions and hypertension; oral hypoglycemic used to treat diabetes in the mother; and, of course, heavy consumption of alcohol. Other drugs may cause gross abnormalities, such as the defects arising from thalidomide. A pregnant woman should, thus, avoid taking any medication without first consulting with her physician.

Injury to a pregnant woman or to a fetus is another cause of congenital anomalies. For example, limbs may be malformed if an intrauterine device (IUD) is not removed early in the pregnancy. Smoking during pregnancy is implicated as one factor in the incidence of abnormally low birth weight in babies, and malnutrition seems to be related to a high incidence of congenital anomalies. The age of the woman at the time she conceives can also be a factor. For example, Down's syndrome occurs more frequently when conception occurs after the age of about 35.

Congenital anomalies have also been attributed to the effects of X-ray examination made early in a pregnancy.

Question: Is it possible to diagnose congenital anomalies in a fetus?

Yes. The most reliable method of diagnosis is to examine a sample of fluid from the amniotic sac, sometime between the fifteenth and eighteenth week of pregnancy. The sample is obtained by amniocentesis. Microscopic examination of the cells in the fluid then reveals possible abnormalities in the chromosomes. Congenital anomalies that can be diagnosed in this way include Down's syndrome, spina bifida, and anencephaly. Sometimes, the diagnostic use of ultrasound can detect abnormalities of the skull or spine.

Question: Can congenital anomalies be treated?

Treatment depends entirely on the nature and severity of the condition. Many anomalies can be treated, but for some there is no treatment.

Question: In what circumstances might abortion be considered?

Abortion might be considered if serious fetal disorders are found early in a pregnancy. The decision to abort rests with the parents and is made after considering the advice of the physician and specialists on the nature of the disorder and the consequences of abortion.

Question: Are congenital anomalies more likely to occur in first-born babies?

No. Statistics disprove this commonly held belief.

Question: Does a congenital anomaly in a baby indicate that subsequent babies will be similarly affected?

Genetic counseling deals with such questions. In many cases it is possible to state risks numerically. For example, a baby with congenital heart disease is likely to be followed by a similarly affected child in 2 percent of pregnancies instead of the ordinary risk of one percent. Spina bifida occurs in about 1 child in every 1,500, but if a previous child was born with the condition, there is about a 1-in-20 to 1-in-50 chance that it will occur in a later child.

Heart Diseases Part IX - Congenital Heart Disease

Congenital heart diseases affect any part of the heart such as heart muscle, valves, and blood vessels. Congenital heart disease refers to a problem with the heart's structure and function due to abnormal heart development before birth. Every year over 30,000 babies are born with some type of congenital heart defect in US alone.

Congenital heart disease is responsible for more deaths in the first year of life than any other birth defects. Some congenital heart diseases can be treated with medication alone, while others require one or more surgeries. The causes of congenital heart diseases of newborns at birth may be in result from poorly controlled blood sugar levels in women having diabetes during pregnancy, some hereditary factors that play a role in congenital heart disease, excessive intake of alcohol and side affects of some drugs during pregnancy. Congenital heart disease is often divided into two types: cyanotic which is caused by a lack of oxygen and non-cyanotic.

1. Cyanotic 

Cyanosis is a blue coloration of the skin due to a lack of oxygen generated in blood vessels near the skin surface. It occurs when the oxygen level in the arterial blood falls below 85-90%. The below lists are the most common of cyanotic congenital heart diseases:

a)Tetralogy of fallot - Tetralogy of fallot is a condition of several congenital defects that occur when the heart does not develop normally. It is the most common cynaotic heart defect and a common cause of blue baby syndrome.

b)Transportation of the great vessels - Transportation of the great vessels is the most common cyanotic congenital heart disease. Transposition of the great vessels is a congenital heart defect in which the 2 major vessels that carry blood away from the aorta and the pulmonary artery of the heart are switched. Symptoms of transportation of the great vessels include blueness of the skin, shortness of breath and poor feeding.

c)Tricuspid atresia - In tricuspid atresia there is no tricuspid valve so no blood can flow from the right atrium to the right ventricle. Symptoms of tricuspid atresia include blue tinge to the skin and lips, shortness of breath, slow growth and poor feeding.

d)Total anomalous pulmonary venous return - Total anomalous pulmonary venous return (TAPVR) is a rare congenital heart defect that causes cyanosis or blueness. Symptoms of total anomalous pulmonary venous return include poor feeding, poor growth, respiratory infections and blue skin.

e)Truncus arteriosus - Truncus arteriosus is characterized by a large ventricular septal defect over which a large, single great vessel arises. Symptoms of truncus arteriosus include blue coloring of the skin, poor feeding, poor growth and shortness of breath. There are many more types of cyanotic such as ebstein's anomaly, hypoplastic right heart, and hypoplastic left heart. If you need more information please consult with your doctor.

2. Non-cyanotic 

Non-cyanotic heart defects are more common because of higher survival rates. The below lists are the most common of non-cyanotic congenital heart diseases:

a)Ventricular septal defect - Ventricular septal defect is a hole in the wall between the right and left ventricles of the heart causing right and left ventricles to work harder, pumping a greater volume of blood than they normally would in result of failure of the left ventricle. Symptoms of ventricular septal defect include very fast heartbeats, sweating, poor feeding, poor weight gain and pallor.

b)Atrial septal defect - Atrial septal defect is a hole in the wall between the two upper chambers of your heart causing freshly oxygenated blood to flow from the left upper chamber of the heart into the right upper chamber of the heart. Symptoms of atrial septal defect include shortness of breath, fatigue and heart palpitations or skipped beats.

c)Coarctation of aorta - Coarctation of aorta is a narrowing of the aorta between the upper-body artery branches and the branches to the lower body causing your heart to pump harder to force blood through the narrow part of your aorta. Symptoms of coarctation of aorta include pale skin, shortness of breath and heavy sweating.

There are many more types of non-cyanotic such as pulmonic stenosis, patent ductus arteriorus, and atrioventricular cana. These problems may occur alone or together. Most congenital heart diseases occur as an isolated defect and is not associated with other diseases.
