VALVULAR HEART DISEASE

This study follows 550 people who receive Abbott annuloplasty rings or bands during surgery to fix leaky mitral or tricuspid heart valves. Researchers will track survival, need for repeat surgery, and symptom improvement for five years after the implant. The goal is to confirm th…

This study tests a home-based exercise program using a mobile app for people who had heart valve procedures. Many patients skip traditional center-based rehab, so this offers a convenient alternative. About 240 participants will be randomly assigned to usual care or the app progr…

This study tests whether a special method of expanding a replacement heart valve during TAVI can reduce harmful thickening of the valve leaflets. About 620 people with severe aortic stenosis who do not have atrial fibrillation will be randomly assigned to either the new expansion…

This study tests a hospital-wide treatment plan for people with heart failure and a leaky mitral valve (secondary mitral regurgitation). The goal is to see if the plan helps doctors identify who will benefit most from a minimally invasive valve repair procedure called MitraClip. …

This study is a registry that collects information from routine hospital care to confirm that Abbott's heart devices are safe and work as intended. About 2,500 people who receive these devices as part of their normal treatment will be followed. The goal is to meet regulatory requ…

This study is following 4,000 adults with heart valve disease to discover new risk factors and understand how certain natural chemicals (metabolites) in the body affect the disease. Researchers will track participants over time and test tissue samples. The goal is to learn more a…

This study is testing whether a special smartwatch can detect heart problems by analyzing pulse signals. Researchers will compare the watch's readings with standard heart tests in 500 adults. If successful, this could lead to easier, non-invasive heart disease screening.

This study looks at 82 adults with severe aortic stenosis who need open-heart surgery to replace their aortic valve. Researchers want to see if a CT scan taken before surgery gives the same valve size measurement as the tools used during the operation. The goal is to find out whi…

This study looks at whether artificial intelligence (AI) can help heart doctors read echocardiograms (heart ultrasounds) more quickly and consistently. Researchers will give AI analysis to cardiologists in real time as they review scans for valve problems like aortic stenosis and…

This study aims to improve how we detect and understand heart disease using a new type of MRI that looks at the heart's microscopic structure. Researchers will compare these advanced scans with standard tests and blood work in 1,000 adults, both healthy volunteers and those with …
