Children having corrective heart surgery through a chest incision often need strong pain medicine. This trial compares two ultrasound-guided nerve blocks, a parasternal intercostal plane block and an erector spinae plane block, both using a mix of bupivacaine and lidocaine. All c…

This study tests a methadone-based recovery plan to improve pain control and reduce opioid use in children after heart surgery. About 500 children aged 3 to 18 will be randomly assigned to either the new methadone plan or standard care. The goal is to see if the new approach lowe…

This study tests whether live, group exercise sessions delivered via video chat can improve fitness in teens (ages 12-19) with certain types of congenital heart disease. 74 participants will either join the remote exercise program or receive standard exercise handouts. The main g…

This study tests whether a nerve block called a parasternal plane block can better control pain during heart surgery in children aged 6 months to 7 years. The block is given after anesthesia and uses a numbing medicine (bupivacaine). Researchers will measure pain using a special …

People born with single-ventricle heart disease often have the Fontan operation, which reroutes blood flow but leaves them with reduced exercise capacity. Researchers at Hacettepe University are measuring lung function and breathing muscle strength alongside treadmill exercise te…

This study looks at why some adults who had the Fontan procedure as children develop serious liver scarring. Researchers will use blood tests, imaging, and liver biopsies to track changes and find early markers of disease. The goal is to better understand the process and pave the…

This study tests a new pulse oximeter worn on the abdomen, designed to measure oxygen levels in infants with congenital heart disease. Researchers compare its accuracy against standard fingertip monitors and direct blood measurements. The device also includes features to reduce e…

This registry tracks 2,000 adults with congenital heart disease who are on the waiting list for a heart or heart-lung transplant. The goal is to understand why some patients get worse or die while waiting, while others improve enough to be removed from the list. By collecting dat…

This study follows 450 babies born with serious heart defects to find early signs of developmental delays by 6 months of age. Researchers want to understand why over half of these children face learning, thinking, or behavior challenges later in life. The goal is to identify risk…

This study aims to collect DNA samples and medical information from 2,000 people with heterotaxy (a condition where organs are arranged abnormally) and related heart defects, along with their family members. Researchers hope to identify the genetic causes of these conditions, whi…

This registry is following 5,000 adults in Switzerland who were born with heart defects. The goal is to collect data on their long-term health, including complications and treatments. By tracking these patients over time, researchers hope to better understand the challenges they …

This study uses small pieces of heart tissue removed during necessary surgery in children with congenital heart disease. Researchers want to understand how calcium controls heart cell contraction and how infant heart cells differ from adult ones. They also aim to improve lab-grow…

This study looks at infants having heart surgery, where the thymus gland is often fully removed to access the heart. The thymus helps build the immune system early in life. Researchers want to see if removing only part of the thymus keeps the immune system stronger and reduces in…

This study follows 10,000 children with congenital heart disease who need surgery for non-heart issues. Researchers want to learn what complications occur and how hospitals use resources. The goal is to create better risk predictions and improve care for these patients.

This study uses special MRI scans to look at how the heart and muscles work together during exercise in children with heart disease or those who have had a heart transplant. Researchers want to learn more about what affects fitness in these kids. About 20 children aged 10 to 18 w…

This study examines whether special pacemakers can effectively treat a common type of fast heart rhythm (atrial tachycardia) in people born with heart defects. Researchers will review medical records from up to 300 patients over 10 years to see if the pacemaker reduces the need f…

This study looks at whether a structured physical activity program can improve thinking and learning in children who had heart surgery. Researchers will compare these children to those having other surgeries and healthy kids. The goal is to see if exercise helps with memory, atte…

This study looks at how well the heart works during exercise compared to at rest in people with congenital heart disease. Researchers will use a special test during a routine heart catheterization to measure blood flow and pressures. The goal is to find out if exercise can uncove…
