Some babies are born with serious heart problems that require surgery very early in life. One of the most complex conditions is called single‑ventricle heart disease. In a healthy heart, there are two pumping chambers that move blood through the lungs and the rest of the body.
Children with single‑ventricle heart disease are born with only one functioning pumping chamber. Because the heart cannot work normally, these children must go through several major surgeries during infancy and early childhood just to survive.
Medical advances over the past few decades have greatly improved survival for these children. Many now live far longer than doctors once expected. However, a new long‑term study suggests that survival is only one part of the story. Many children with this condition continue to face serious health and developmental challenges as they grow into adolescence.
Researchers from Duke Health and the Pediatric Heart Network followed hundreds of children with single‑ventricle heart disease for more than 16 years.
Their goal was to understand how these children do over the long term and what factors may influence their health. The study included 549 children who were born with the condition and underwent early heart surgery.
The results showed that life with this heart condition often remains difficult even after successful surgeries. Over the course of the study, 87 percent of the children either died or developed a major health problem by adolescence.
Only about 12 percent reached their teenage years without a serious complication. The findings were published in the Journal of the American College of Cardiology.
Doctors have long known that children with single‑ventricle heart disease require multiple operations. The most common treatment is a series of staged surgeries that gradually change the way blood flows through the heart and lungs.
These procedures allow the single working chamber to pump blood more effectively. Although the surgeries can save lives, they do not fully repair the heart. The heart still works differently from a normal one, which can create long‑term health concerns.
To better understand the overall well‑being of these children, the research team created a new way of measuring long‑term outcomes. They developed what is called a global rank score.
This system looks at more than just survival. It also considers factors that families say are important, such as how well a child can function in daily life, how strong their heart remains, and how good their overall quality of life is.
The researchers found that many children gradually developed challenges as they grew older. Some had delays in adaptive behavior, meaning they struggled with everyday skills such as communication, learning, and independence.
Others experienced reduced heart function or difficulty keeping up with normal physical activities. In many cases, these issues did not appear immediately after surgery but developed slowly over time.
One group of children faced particularly difficult outcomes. Babies who were born prematurely had a much higher risk of complications.
More than 60 percent of premature infants in the study died during the follow‑up period, and only about 3 percent reached adolescence without major problems. These results suggest that preventing premature birth and supporting healthy pregnancies could help improve survival for children with this heart condition.
The study also revealed important information that may help doctors make better treatment decisions in the future. During the first surgery in infancy, surgeons often use one of two types of shunts to help blood flow through the heart. Overall, both shunt types showed similar long‑term results.
However, the researchers noticed that babies who already had moderate or severe leakage in the tricuspid heart valve tended to have worse outcomes when a right‑ventricle shunt was used. This finding may help doctors choose the best surgical approach for certain patients.
Another surprising discovery was that outcomes varied between hospitals. Some medical centers achieved lower death rates during the early surgical period.
Others were more successful in providing long‑term follow‑up care and rehabilitation services. These differences suggest that hospitals could improve results by sharing knowledge and adopting the most effective treatment strategies.
Dr. Kevin D. Hill, chief of pediatric cardiology at Duke University School of Medicine and the study’s corresponding author, explained that families often believe surgery will completely fix the problem.
In reality, these children usually need specialized medical care for the rest of their lives. Ongoing monitoring, therapy, and support services are essential to help them grow and succeed.
Children with single‑ventricle heart disease may require help in many areas beyond heart care. Some benefit from physical therapy to strengthen their bodies and improve endurance.
Others need learning support at school or mental health care to help manage emotional challenges. Regular medical visits remain important to watch for changes in heart function.
The findings of this long‑term study provide valuable information for families and doctors. By understanding the typical health paths of these children, medical teams can prepare families for what may happen over time and offer earlier support when problems begin to appear.
At the same time, the research highlights opportunities for improving care. Better pregnancy health, improved surgical decisions, stronger follow‑up programs, and better sharing of hospital practices could all help children with this condition live healthier lives.
Overall, the study provides a clearer and more realistic picture of life with single‑ventricle heart disease. It reminds both families and doctors that survival after surgery is only the first step, and that long‑term care, developmental support, and coordinated medical services are essential for helping these children reach their full potential.
The research findings were published in the Journal of the American College of Cardiology.
The results of this study are important because they show that treating single‑ventricle heart disease is not just about performing successful surgery. The condition affects many parts of a child’s life over many years. The use of a broader measure such as the global rank score helps doctors look beyond survival and focus on quality of life.
The research also shows that early health factors, such as premature birth or valve problems, may influence long‑term outcomes.
While the findings may seem concerning, they also provide a roadmap for improving care. With better monitoring, targeted therapies, and stronger long‑term support systems, future patients may achieve better outcomes and a higher quality of life.
