5 Things I Wish I Knew When My Daughter Was Diagnosed with Complex Congenital Heart Disease

When my daughter was born, my world shifted in a heartbeat. I had no idea that within the first two days of her life, doctors would rush in with grim expressions, telling me something I never expected: my baby girl had been born with Hypoplastic Left Heart Syndrome (HLHS), basically she was born with just half a heart. I would come to learn that hers was the most severe heart defect a person can have, also known as Complex Congenital Heart Disease (CCHD). It was a diagnosis I had never heard of, and the weight of it was more than I could bear. In those first few days, I was lost, overwhelmed, and desperate for answers. Looking back, there are five things I wish I had known, things that could have helped me better navigate the overwhelming emotions and challenges that lay ahead.

1. CCHD Is Rare, But It’s Real

Complex Congenital Heart Disease is not something every parent expects to hear. It’s a term used for a variety of severe heart conditions that are present at birth. According to the Centers for Disease Control and Prevention (CDC), about 1 in 100 babies is born with a congenital heart defect. However, CCHD is rarer, affecting around 1 in 4,000 to 1 in 10,000 births depending on the specific condition. That means that while it’s not common, it’s certainly not unheard of, either. Knowing this would have helped me understand that, while my daughter’s journey was unique, she wasn’t alone.

2. The Emotional Rollercoaster Is Real – and Okay to Feel

In the chaos of those early days, I was flooded with emotions—fear, confusion, and sadness. The term “rollercoaster” doesn’t do justice to what it’s like to go through the highs and lows of CCHD. One day, my daughter would be stable, and we thought maybe we’d go home. The next, I was praying for a miracle during an emergency intervention. It’s a constant state of uncertainty. I wish I had known that it’s okay to feel overwhelmed and that there is no “right” way to grieve or cope. I felt a lot of guilt, as though somehow I had failed my baby by not knowing she had this condition or wondered if it were something I’d done during the pregnancy that caused this horrible condition. What I came to learn, though, is that it’s not my fault. I couldn’t have known and didn’t do anything wrong during the pregnancy; it’s just a thing that can happen, and that’s a hard truth to accept.

3. You Will Find a Community

In those early days, I felt isolated—like no one could truly understand the weight of what I was going through. But as time went on, I found other parents who had been through similar experiences. There are support groups, online communities, and medical professionals who specialize in congenital heart disease. Reaching out and connecting with others who had walked the same path was a game-changer. It gave me hope and reminded me that my daughter’s diagnosis didn’t define her future.

4. The Medical Journey Will Be Long

CCHD is not a condition that gets solved overnight. The medical journey is long and often requires multiple surgeries, heart catheterizations, and follow-ups. As a parent, I didn’t fully understand the complexity of her condition or the level of care she would need. While I knew her doctors were highly skilled, I didn’t realize just how much we would depend on them and the medical community. I also didn’t know how much of her healing would involve small victories: when she grew stronger after surgery, when she started to smile again, or when she could finally breathe without assistance. It’s a journey that demands patience, resilience, and the understanding that each day, however small, is a victory.

5. The Hope Is Real

As difficult as the journey was, I’ve learned that there is real hope for children with CCHD. When I initially learned of my daughter’s condition my first question to doctors was, “can’t she just get a heart transplant”? Doctors informed me that getting a heart transplant was not the “cure” it seemed to be. I learned that heart transplant comes with many complications, medications, poor quality of life and more. The doctors told me that she would have a better quality of life with just half a heart than if she had a transplanted. I had no idea, and I don’t think most people know that. When she was 6 months old, during recovery after her second open heart surgery, I learned of research being conducted by Dr. Doris Taylor.  At that time she was running the regenerative medicine department at Texas Heart Institute. Dr. Taylor was literally building hearts using a patient’s own stem cells, meaning that a heart transplant would not require immunosuppression and a lifetime of sickness. The article I read gave me hope for the first time since she’d been born that maybe she would grow up, maybe she would have kids of her own, maybe she would live to an old age- all things doctors told me were not likely for her. I decided to go meet Dr. Taylor and that is how Building the Cure Foundation was born. I found that taking an action helped me to not only cope with the heartbreak of the situation, but also gave me hope to carry on. While the survival rate for children born with complex heart conditions has improved dramatically over the years, the road for CCHD patients and families is challenging. I wish this research was further along but the encouraging part is that there is light at the end of the tunnel, even when it feels like the darkest of times.

In the years since my daughter’s diagnosis, I’ve learned that parenting a child with CCHD requires a blend of hope, resilience, and acceptance. I still don’t have all the answers, but I do know this: my daughter is a fighter, and so am I. I wish I had known that early on, but I’m grateful to have learned it through this journey. Every single day is a gift, and with the right support, love, and medical care, there is hope for children born with Complex Congenital Heart Disease.
