Congenital heart malformation

This trial investigates how the Fontan surgery, which reroutes blood flow in children born with a single heart ventricle, affects the liver and heart. Researchers use MRI scans and blood tests to measure fibrosis (scarring) and lymphatic congestion. They also test whether spirono…

This trial investigates whether cardiac resynchronization therapy (CRT) — a special type of pacing — can improve how far people can walk in six minutes. It includes adults with congenital heart disease where the right ventricle pumps blood to the body (systemic right ventricle). …

This study tests a two-part virtual program for teens aged 13-18 with Fontan physiology, a type of single-ventricle heart disease. The first part is a small-group wellness education session each week for 5 weeks, led by a psychologist. The second part is a personalized home exerc…

This study tested whether a live-video-supervised exercise program could improve fitness in children and teens (ages 8-19) born with a single ventricle, a condition often treated with the Fontan procedure. Participants exercised three times a week for three months, then a mainten…

This study tested whether a low dose (4.5 mg) of naltrexone, a drug already used for alcoholism, can improve physical health and quality of life in people with vasculitis. Sixty participants took either the drug or a placebo daily for six weeks. The goal was to see if the drug le…

This study tested if combining cartoon-watching with nurse interaction could ease pain in children after heart surgery. 70 kids aged 3-7 took part; half got standard pain care, and the other half also watched cartoons with a nurse. The goal was to see if this fun, non-drug approa…

This study looked at whether using a Passy-Muir valve (a small device that helps people with a tracheostomy speak) can also improve how far they can walk. 26 adults with a tracheostomy completed several 6-minute walk tests, alternating between using the valve and leaving the trac…

This study looks at how the heart medication digoxin is processed in infants born with single ventricle heart disease. Researchers will collect blood samples during routine care to measure drug levels. The goal is to better understand dosing, but the study does not change the inf…

This study uses French national health data to compare the risk of major heart problems—like heart attack, stroke, and death—in people with Takayasu arteritis versus similar people without the disease. It also looks at how steroid use may affect these risks. The goal is to better…

This study looked at 200 men and women who had surgery to repair a small ascending aortic aneurysm (5.0-5.5 cm). Researchers wanted to see if gender affects early and long-term outcomes like death, heart attack, or bleeding. The goal is to understand why women might have worse re…

This study looked at how well surgery works for people with an enlarged aorta (aneurysm) in the chest. Researchers compared outcomes in 50 patients who had surgery versus those who did not, tracking deaths and how fast the aorta grew over time. The goal was to better understand w…

This study tested whether a newer type of MRI called 4D flow can more accurately measure leakage in the pulmonary valve and heart chamber size in people born with tetralogy of Fallot who had corrective surgery. Researchers compared 4D flow MRI with standard 2D MRI in 21 patients …

This completed study looked at 44 patients who had lung cancer surgery to understand how the arteries in the lungs can vary from person to person. Using CT scans and 3D models, researchers mapped these variations to help surgeons avoid complications during lobectomy. The goal was…

This completed study reviewed the medical records of 210 people with aortitis (inflammation of the aorta) or retroperitoneal fibrosis (scar tissue in the abdomen). The goal was to find patterns in symptoms, lab tests, and imaging that could help doctors tell different types of th…

This study looked at whether a small device called an implantable loop recorder can be safely placed in newborns who have only one working heart chamber. Ten babies received the monitor during their first heart surgery. The goal was to see if the device could continuously track h…

This study looked at 11 people with a repaired heart condition called tetralogy of Fallot who needed a new pulmonary valve. Researchers used MRI scans to measure heart muscle stiffness (fibrosis) and how well the heart pumped during rest and exercise. The goal was to see if these…
