Aortic valve calcification

This study looks at whether people with an On-X mechanical aortic heart valve can safely take a lower dose of the blood thinner warfarin. The goal is to reduce bleeding complications while still preventing dangerous blood clots. Researchers will follow 510 adults for up to 5 year…

This study tests a new device called the DurAVR™ THV System, a replacement heart valve placed through a small tube in an artery, for people with severe aortic stenosis (a narrowed heart valve). The trial involves 150 participants and aims to see if the device is safe and works we…

This early study tests a new device called the DurAVR™ heart valve in 15 people aged 65 and older with severe aortic stenosis, a condition where the heart's aortic valve becomes narrowed. The valve is implanted through a catheter (TAVR) without open-heart surgery. The main goals …

This study compares a new, less invasive shockwave device to standard surgery for treating severe calcium buildup in the main leg artery. The shockwave uses sound waves to break up the calcium, while surgery involves physically removing the blockage. Researchers want to see if th…

This early study is testing a new device called the DurAVR™ THV System, which is a replacement heart valve placed through a small tube in the leg (TAVI procedure). The study includes 40 people with severe aortic stenosis or a failed surgical valve. The main goal is to see if the …

This study tests whether a bedside device called Quantra can help doctors decide when to give blood transfusions during complex heart surgery. The device measures how well a patient's blood clots in real time. Researchers hope this will reduce the number of blood products (like r…

This study looks at how safe and effective the Avalus Ultra artificial heart valve is for people with aortic valve disease. About 190 participants will be followed for one year after surgery to check for problems like blood clots or valve failure, and to see how well the valve wo…

This study is testing a small mechanical heart valve (15mm) in 20 children who need their aortic valve replaced due to disease or damage. The valve is designed to last and is monitored for safety and function over 5 years. Children will need lifelong blood-thinning medication to …

This study tests whether evogliptin, a drug originally for diabetes, can slow calcium buildup in the aortic valve of people with mild-to-moderate aortic stenosis. About 580 adults will take either the drug or a placebo daily for two years. The main goal is to see if the drug redu…

This study follows 255 Chinese patients who received the INSPIRIS RESILIA aortic valve to see how safe and well it works over several years. Researchers track problems like valve failure, blood clots, bleeding, and the need for another surgery. The goal is to confirm the valve's …

This phase 3 trial tests whether colchicine, an anti-inflammatory drug, can slow the progression of aortic valve stenosis—a narrowing of the heart's aortic valve that currently has no drug treatment. The study enrolls 150 people with moderate, symptom-free valve disease. Particip…

This study follows 50 people who previously received an INSPIRIS RESILIA aortic valve and now need a valve-in-valve procedure because their original valve is not working well. Researchers will track complications like death, stroke, bleeding, and valve movement, as well as how we…

This registry follows 500 people receiving a specific type of surgical aortic valve replacement (the INSPIRIS RESILIA valve) for up to five years. Researchers are tracking how pre-existing conditions like kidney disease, diabetes, and high blood pressure affect survival and valve…

This study collects tissue samples from 1,000 people having heart valve surgery to find genetic causes of calcific aortic valve disease. Researchers will compare normal and diseased tissue to understand why the disease develops. Participants must be at least 20 years old and have…

This study was designed to see if early mobilization and a simple bottle-based breathing device (Bottle-P.E.P.) could improve breathing and physical function in people recovering from heart valve surgery. The trial was withdrawn before enrolling any participants, so no results ar…

This study looks at how a common heart valve procedure called TAVI changes the gut microbiome in older adults with aortic stenosis. Researchers will collect blood and stool samples before and three months after TAVI to measure bacterial byproducts and diversity. The goal is to se…

This study will enroll 210 adults aged 65 and older with early aortic stenosis (a heart valve narrowing) to see if an artificial intelligence tool can better predict how fast the disease worsens. Participants will have standard echocardiograms, and researchers will compare the AI…

This study tests a new sensor worn on the skin that measures lactate levels without needles. It involves 20 adults recovering from heart bypass or valve surgery. The goal is to see if the sensor works as well as standard blood tests, which could make monitoring more comfortable a…

This study aims to uncover the genetic roots of aortic aneurysms and valve disease by analyzing tissue and blood samples from 3,000 participants. Researchers will look for new disease-causing genes and factors that affect disease severity. The goal is to build a biorepository to …

This study compares two methods for deciding which blocked heart arteries need bypass during valve surgery. The standard method uses angiography (X-ray dye), while the new method uses a computer calculation called QFR. About 792 patients will be randomly assigned to one method, a…
