This study tests a new device called the PULSTA valve, which is placed inside the heart through a tube in a blood vessel, avoiding open-heart surgery. It is for 58 people with a leaky or narrowed pulmonary valve, often due to a birth defect. The goal is to see if the valve is saf…

This large study is testing whether a lower blood pressure target can reduce major heart problems like heart attacks, strokes, and heart failure in people with type 2 diabetes. About 9,500 participants with high blood pressure and high cardiovascular risk are being randomly assig…

This study follows 300 people with blocked leg arteries who received a treatment using a balloon coated with paclitaxel and vitamin E. The goal is to see if the balloon keeps the artery open and prevents the need for repeat procedures over one year. Participants are adults with m…

This study is tracking 200 people with blocked leg arteries who are receiving a special balloon coated with the drug paclitaxel (GENOSS PCB). The balloon is inflated inside the artery to open it and release the drug, which helps prevent the artery from narrowing again. Researcher…

This study compares two solutions, Custodiol and Custodiol-N, used to protect the heart during surgery for children with congenital heart defects. About 100 children will receive one of the two solutions while on a heart-lung machine. The goal is to see which one is safer and bet…

This study is testing a new device called the GORE PV1 to replace the pulmonary valve and rebuild the right ventricular outflow tract in people with congenital heart defects. The device is designed to improve blood flow from the heart to the lungs. The study includes 15 participa…

This study tests whether giving patients capsules containing gut bacteria (called Probacine) before and after heart surgery can reduce gut injury and organ failure. Researchers will enroll 500 adults undergoing cardiovascular surgery. The goal is to see if changing the gut microb…

This study looks at a new device to fix leaky pulmonary valves in people born with heart defects. About 150 people will get the Edwards SAPIEN 3 valve placed inside a special stent. The goal is to see if the valve works well and stays in place without major problems.

This study tests a new device (Alterra Prestent) used with a replacement heart valve (SAPIEN 3) to fix a leaky pulmonary valve in people born with heart defects. About 86 participants with moderate or severe leakage will get the device through a tube in a blood vessel, avoiding o…

This study is testing a new type of heart valve called the Harmony TPV, which is placed using a thin tube (catheter) instead of open-heart surgery. It is for people with congenital heart disease who have a leaky pulmonary valve. The study will check if the valve works well and is…

This study explores whether a simple, non-invasive leg movement test can measure blood vessel health in older adults. Researchers will use ultrasound to track blood flow changes after a passive leg movement, comparing young healthy people and older patients undergoing heart tests…

This large study tested whether taking daily vitamin D3 and omega-3 (fish oil) supplements can lower the risk of developing cancer, heart disease, or stroke. Over 25,000 healthy older adults (men 50+, women 55+) took the supplements or placebos for about 5 years. The goal is to s…

This study tests a nurse-led education program designed to help women in cardiac rehab address sexual concerns after a heart event. Sixty-six women will be randomly assigned to either the program or usual care. The goal is to see if the program improves sexual function, mood, and…

This study tests whether a web-based decision aid app can reduce stress and improve decision-making for parents whose baby is diagnosed with a life-threatening congenital heart defect. 135 parents are randomly assigned to use the app alone or with an added values clarification ex…

This study was designed to compare electrical and mechanical activation of the right ventricle in adults who had surgery for Tetralogy of Fallot, a congenital heart condition. Researchers planned to use 3D mapping and imaging to see if electrical signals match the heart's physica…

This study tracks 120 adults with heart disease and at least two other long-term illnesses to see how often dangerous drug interactions happen. Researchers check medications, including over-the-counter and herbal products, and follow participants for a year. The goal is to unders…

This study tracks over 1,700 heart patients who had hip or knee replacement surgery. Researchers want to see how often bleeding or blood clots happen in the months after surgery. The goal is to find better ways to prevent these complications.

This study looks at 224 adults who had surgery as children for a heart defect called tetralogy of Fallot. Researchers are using MRI scans and blood tests to measure scarring in the heart muscle. They want to see if this scarring is linked to serious heart problems like arrhythmia…

This study will observe 200,000 Chinese adults with heart disease to see how their heart and lung function changes over 5 years. Participants will take a special exercise test to measure their fitness. Researchers hope to find better ways to predict future heart problems like hea…

This study follows 2000 people with dilated cardiomyopathy (a weakened, enlarged heart) over several years to learn how genetics and heart scarring affect the disease. Participants give blood for genetic testing and have heart MRI scans. The goal is to improve diagnosis and pave …

This study looks at how being in a hospital intensive care unit (ICU) after heart surgery affects your body's natural sleep-wake cycle. Researchers will track sleep patterns and thinking ability in 15 adults to see if disrupted rhythms slow down recovery. The goal is to understan…

This study aimed to see if using a special pad along with a standard closure device could help patients get out of bed sooner after a heart catheterization. It was planned for adults having the procedure through the groin. However, the study was withdrawn before any participants …

This study follows 347 heart surgery patients to understand why some develop swallowing problems (dysphagia). Researchers will use special camera tests to watch how patients swallow and look for risk factors. The goal is to create simple tools that doctors can use at the bedside …
