This study tests whether a 12-week home-based high intensity interval training program can improve exercise capacity in people aged 12 to 45 with a congenital heart defect that required a surgical connection between the right ventricle and pulmonary artery. Participants are rando…

This study tests whether a gentle brain stimulation technique called tACS, used at home for 5 days a week over 4 weeks, can improve memory and thinking in 40 young people aged 14-25 with 22q11.2 deletion syndrome. The stimulation is personalized based on each participant's MRI an…

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…
