Pulmonary valve stenosis

This trial tests whether a cutting balloon, a catheter with tiny blades that score the vessel wall before expanding, can safely widen branch pulmonary arteries that resist standard low-pressure balloon dilation. Researchers will compare the cutting balloon to high-pressure balloo…

This study looked at the SAPIEN XT heart valve, which is placed through a thin tube (catheter) to fix a failed valve in the heart's right ventricle. Researchers wanted to confirm it is safe and works well. They enrolled 57 people with a narrowed or leaky heart valve conduit. The …

This study tested a new valve called the Pulsta® Transcatheter Pulmonary Valve in 15 people with congenital heart disease and a faulty pulmonary valve. The valve is implanted through a catheter, avoiding open-heart surgery. Researchers checked if the valve improved blood flow and…

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…
