What Is Congenital Heart Disease
Congenital heart disease, often called CHD, is a structural abnormality of the heart that is present from birth. The word congenital simply means present at birth. It does not mean caused by something you did or did not do during pregnancy. It does not mean your child is fragile. It means their heart developed differently, and that difference requires attention, care, and in many cases, intervention.
CHD is the most common birth defect in the world. In the United States alone, approximately one in every one hundred babies is born with some form of congenital heart disease. That is more than forty thousand children every year. More than all childhood cancers combined.
You are not alone in this. The community of families who understand exactly what you are going through right now is larger than most people know. And it is one of the most connected, resilient, and generous communities in the world.

Your child's diagnosis is serious. It is also survivable in ways that would have been unimaginable a generation ago. Modern pediatric cardiology has transformed what CHD means for children and their futures. Your child is living in the best possible era of care for this condition.
02
The First Days After Diagnosis
The first days after a CHD diagnosis are among the hardest any parent will ever face. The information comes fast. The decisions feel enormous. The fear is total. And underneath all of it is a love so fierce it has nowhere to go, pressing against the walls of everything you thought you knew about your life.
This is normal. Everything you are feeling is normal. The shock. The grief. The desperate search for information at hours when the rest of the world is asleep. The way your mind keeps returning to the moment you heard the words, playing it back, looking for something you missed, something that would make it make sense.
There is nothing you missed. This was not caused by something you did. CHD occurs during the earliest weeks of fetal heart development, often before most people even know they are pregnant. It is not a failure of love or care or attention. It is a variation in development that medicine has learned, over decades of extraordinary work, to address with increasing skill and success.
In the first days, your only job is to be present. To ask questions. To let the medical team do what they have spent years training to do. And to hold your child with everything you have.
Here is what the first days do not require of you. They do not require you to have all the answers. They do not require you to be strong in front of everyone, all the time. They do not require you to understand everything immediately. Medicine is complex. Cardiology is a subspecialty that cardiologists spend years mastering. You are not expected to become fluent in it overnight.
What the first days do require is that you show up. Ask questions even when you feel embarrassed by them. Write things down because shock affects memory. Bring someone with you to appointments when you can. And give yourself permission to fall apart in private, because that is not weakness. That is the honest response to something genuinely hard.

Common Types of CHD Explained
There are more than forty recognized types of congenital heart defects, ranging from simple conditions that may require no intervention to complex ones that require multiple surgeries over a lifetime. Here are some of the most commonly diagnosed, explained in plain language.
Ventricular Septal Defect (VSD)
A hole in the wall between the lower two chambers of the heart. It is the most common CHD diagnosis. Small VSDs often close on their own. Larger ones may require surgical repair or catheter-based intervention.
Atrial Septal Defect (ASD)
A hole in the wall between the upper two chambers of the heart. Like VSDs, small ASDs may resolve without treatment. Larger ones are typically repaired through catheterization or open-heart surgery.
Tetralogy of Fallot (TOF)
A combination of four heart defects present at birth. It is the most common cyanotic heart defect, meaning it causes reduced oxygen levels in the blood. Surgical repair is typically performed in infancy and outcomes have improved dramatically in recent decades.
Hypoplastic Left Heart Syndrome (HLHS)
A condition in which the left side of the heart is severely underdeveloped. It is one of the most complex CHD diagnoses and requires a series of three surgeries in the first years of life. Survival rates have improved significantly with advances in surgical technique and postoperative care.
Transposition of the Great Arteries (TGA)
A condition in which the two main arteries leaving the heart are switched. Without surgical correction, TGA is life-threatening. With the arterial switch operation, performed in the first weeks of life, outcomes are generally excellent.
Pulmonary Stenosis
A narrowing of the pulmonary valve that restricts blood flow from the heart to the lungs. Mild cases may require no treatment. More significant narrowing is treated through balloon valvuloplasty or surgery.
Coarctation of the Aorta
A narrowing of the aorta, the main artery carrying blood from the heart to the body. It is typically repaired surgically or through catheter-based intervention and outcomes are generally very good with timely treatment.
Patent Ductus Arteriosus (PDA)
A persistent opening between the aorta and the pulmonary artery that normally closes shortly after birth. Small PDAs may close on their own. Larger ones are treated with medication, catheter-based closure, or surgery.
Your child's specific diagnosis may not be on this list. There are more than forty recognized forms of CHD, and many children are diagnosed with combinations of defects. Your pediatric cardiologist is the right person to explain exactly what your child's heart looks like and what it means for their care.
04
Understanding Your Medical Team
One of the most disorienting aspects of a CHD diagnosis is the sudden appearance of a large, specialized medical team. Names and titles multiply. Different people say different things. It can feel like everyone knows something you do not, which is because they do, and that asymmetry of knowledge is genuinely frightening when it is your child at the center of it.
Understanding who these people are and what role they play can help you feel less like a bystander and more like a member of the team making decisions for your child.
Pediatric Cardiologist
A physician who specializes in diagnosing and managing heart conditions in children. This person will be the central figure in your child's ongoing cardiac care. They interpret echocardiograms, manage medications, and coordinate your child's overall cardiac treatment plan.
Pediatric Cardiac Surgeon
A surgeon who specializes in operating on children's hearts. If your child requires surgery, this person will perform it. Do not hesitate to ask about their experience specifically with your child's diagnosis. Volume matters in complex cardiac surgery.
Cardiac Intensivist
A physician who manages care in the cardiac intensive care unit (CICU) after surgery. They specialize in the complex post-operative period when your child's heart is recovering.
Cardiac Nurse Practitioner or PA
Advanced practice providers who work closely with your cardiologist. They are often your most accessible point of contact for questions between appointments and are invaluable navigators of the system.
Cardiac Social Worker
A specialist who helps families navigate the emotional, financial, and logistical challenges of a CHD diagnosis. If your hospital has one, use them. They know things about available resources that no one else will think to tell you.
Pediatric Cardiac Anesthesiologist
A physician who specializes in administering anesthesia to children during cardiac procedures. Their expertise is one of the most critical components of a successful cardiac surgery.
You are allowed to ask any question you have, no matter how basic it feels. You are allowed to ask for things to be explained again, in different words. You are allowed to disagree, to seek a second opinion, and to advocate for your child with every tool available to you. That is not being difficult. That is being a parent.
05
Questions to Ask Your Cardiologist
Walking into a cardiology appointment without a list of questions is like walking into a foreign country without a map. You will be overwhelmed, and you will leave with things unsaid that mattered. Write these down before your next appointment. Bring someone with you to help you remember what was said.
- Can you explain my child's specific diagnosis in plain language, and draw or show me what their heart looks like compared to a typical heart?
- What is the short-term plan for my child's care, and what are the possible paths their treatment could take over the next year?
- Does my child need surgery? If so, when, and what type? What are the risks and the expected outcomes?
- How many children with this specific diagnosis has your team treated? What are your outcomes for this procedure?
- What symptoms should send us to the emergency room immediately, and what symptoms can wait for a regular appointment?
- Are there any activity restrictions? What can my child do, and what should they avoid?
- What medications will my child need, and what are the side effects I should watch for?
- Will my child need additional surgeries or interventions in the future? What is the long-term trajectory of their condition?
- What does lifelong cardiac follow-up look like for my child?
- Are there any clinical trials or new treatments that might be relevant to my child's diagnosis?
- Can you connect us with a cardiac social worker, a family support coordinator, or a CHD family community?
- Who do I call after hours if I have concerns, and how quickly can I expect a response?
There is no such thing as a question too small to ask when it is your child's heart. Write every question down as it occurs to you. The ones that come at two in the morning are often the most important ones.
06
If Your Child Needs Surgery
Learning that your child needs heart surgery is one of the most frightening sentences a parent can hear. It is also, in many cases, the sentence that stands between your child and a longer, healthier life. Modern pediatric cardiac surgery is one of medicine's most profound achievements, and the teams performing it have dedicated their careers to exactly this work.
Here is what it helps to know before surgery day.
- Ask your surgeon specifically how many times they have performed this procedure on children with your child's exact diagnosis. Experience and volume are directly correlated with outcomes in complex cardiac surgery.
- Ask about the hospital's cardiac ICU. The quality of post-operative care is just as important as the surgery itself. A strong CICU team makes an enormous difference in recovery.
- Ask what the recovery timeline looks like, both in hospital and at home, so you can plan and prepare your family accordingly.
- Arrange for someone to be with you on surgery day. You should not be alone in that waiting room. If you have no one who can come, ask the hospital's social worker to connect you with a volunteer or chaplain service.
- Bring something to hold in the waiting room. A book, a journal, something for your hands. The waiting is long and the mind will go to frightening places without something to anchor it.
- Ask the surgical team what they will tell you during surgery, how often, and through what channel. Knowing when to expect updates is the difference between manageable waiting and unbearable silence.
- Prepare your other children and family members in age-appropriate ways before surgery day. Children handle things better when they are told the truth in language they can understand.
- Give yourself permission to cry in the car before you walk in. The composure you show in front of your child does not have to be the whole truth of what you are carrying.
The moment they take your child back is the hardest moment. And then the surgery begins, and the team that has spent years training for exactly this takes over. Trust that training. It is extraordinary. And your child is in the hands of people who chose this work because they believe in what it makes possible.
07
The Emotional Reality for Families
The emotional experience of a CHD diagnosis is rarely talked about with the same seriousness as the medical one. This guide will not make that mistake.
What CHD families experience, in the days and months and years following a diagnosis, is a form of trauma. Not a metaphor for trauma. Actual trauma, with all of the physiological and psychological weight that word carries. Research consistently shows that parents of children with CHD report rates of anxiety, depression, and post-traumatic stress significantly higher than the general population.
This is not weakness. It is a biological and psychological response to genuinely threatening circumstances. Your nervous system is doing exactly what it is designed to do when someone you love is in danger.
What it means practically is that you need support too. Not just your child. You. Your partner, if you have one. Your other children. Your whole family is living inside this diagnosis, and all of you deserve care.
For You as a Parent
Ask your child's hospital for a referral to a therapist who has experience with families of medically complex children. This is not a sign that you cannot handle things. It is a sign that you understand what you are carrying and are taking it seriously.
For Your Partnership
CHD puts enormous strain on relationships. Partners often grieve differently, communicate differently, and cope differently. These differences can pull people apart if they go unaddressed. Name them. Talk about them. Seek couples support if you need it.
For Your Other Children
Siblings of children with CHD often struggle silently. They may feel invisible, guilty, or frightened in ways they do not have words for. Age-appropriate honesty and deliberate one-on-one time with each sibling makes a meaningful difference.
For Yourself in the Long Run
The acute crisis phase of a CHD diagnosis eventually gives way to a new kind of normal. Many parents find that the anxiety does not disappear after the surgery. It shifts into a vigilance that lives in the body for years. This is worth addressing with a professional, not carrying alone.
You cannot pour from an empty vessel. Taking care of yourself is not selfish. It is the most practical thing you can do for your child, because they need you whole, over the long haul, not just today.
08
Practical Steps to Take Now
When everything feels overwhelming, a concrete list of actions can be a lifeline. Here are the practical steps that matter most in the early weeks after a CHD diagnosis.
- Request a complete copy of all medical records, test results, and imaging related to your child's diagnosis. Keep these organized in a binder or digital folder. You will need them more than once.
- Contact your insurance company to understand your coverage for pediatric cardiology, cardiac surgery, and cardiac ICU care. Ask specifically about out-of-network coverage if the best care for your child's diagnosis is not in your network.
- Ask the hospital about financial assistance programs. Most major pediatric cardiac centers have financial counselors and access to charitable funds for families facing extraordinary medical costs. Ask before you assume you do not qualify.
- Notify your employer about what you are going through. The Family and Medical Leave Act provides protections for parents of seriously ill children. Know your rights before you need them.
- If your child will require surgery at a hospital far from home, ask about family housing options. Most major children's hospitals have partnerships with Ronald McDonald Houses or similar programs that provide subsidized housing for families.
- Build your support network deliberately. Identify specific people who can help with specific things: someone to take your other children to school, someone to bring meals, someone to sit with you in waiting rooms. People want to help. Let them.
- Begin a journal or log of your child's symptoms, medications, and appointments. This record becomes invaluable as your child's care becomes more complex over time.
- Connect with a CHD family organization. Heartbeat Forward, Mended Little Hearts, the Adult Congenital Heart Association, and the Congenital Heart Public Health Consortium all offer resources, community, and support specifically for CHD families.

Life After Diagnosis: The Long View
In the acute early days of a CHD diagnosis, the long view feels inaccessible. You cannot think about ten years from now when you are trying to get through this afternoon. That is completely understandable, and you do not need the long view right now.
But when you are ready for it, here is what it looks like.
Most children diagnosed with CHD today will grow up. They will go to school, make friends, fall in love, build careers, and live lives that are meaningful and rich and full. The medical complexity of their condition will be a thread running through those lives, requiring attention and management, but it will not be the whole of who they are. It will be one part of a complete person.
CHD is a lifelong condition. Most forms of CHD, even when surgically repaired, require ongoing cardiac monitoring throughout life. As your child grows, they will need age-appropriate education about their own heart, their own medical history, and how to advocate for themselves within the healthcare system. That education starts now, with the conversations you have at home, and it grows alongside them.
The transition from pediatric to adult cardiac care, typically around age eighteen, is one of the most important passages in a CHD survivor's life. It requires planning, preparation, and intentional support. You do not need to think about it today. But when the time comes, it deserves serious attention.
Your child's future is not written by their diagnosis. It is written by the care they receive, the love that surrounds them, and their own extraordinary capacity to grow into something the world did not expect. Trust that capacity. It is real.
A Word From Adrian
I wrote this guide because I believe that information delivered with compassion is one of the most powerful forms of advocacy there is.
I am not a cardiologist. I am not speaking to you as a medical authority. I am speaking to you as someone who has spent years immersed in the CHD community, listening to families, reading the research, and building an organization dedicated to the belief that visibility and support change outcomes.
I founded Heartbeat Forward because I looked at what CHD families face, the diagnosis, the surgeries, the financial strain, the emotional weight, the isolation, and I could not find a reason to look away. So I did not. And I will not.
If this guide helped you in any way, if it gave you one question to ask, one thing to feel less alone about, one moment of clarity in what has probably been a very dark few days, then it has done its job.
You are not alone in this. Your child is not alone in this. And the work we are doing at Heartbeat Forward, the advocacy, the awareness, the care packages for children in cardiac units, the push for funded surgeries, all of it is for families exactly like yours.
We see you. We are with you. And we are not going anywhere.
