VALVULAR HEART DISEASE

This study compares two stomach-acid-lowering drugs—tegoprazan and rabeprazole—in about 3,300 heart disease patients who take blood thinners and are at high risk for stomach bleeding. The goal is to see if tegoprazan works as well as rabeprazole at preventing serious gut problems…

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. The goal is to confirm the devices work wel…

This study tests a home-based cardiac rehabilitation program delivered through a custom app for people who have had a heart valve procedure. Participants who choose not to attend center-based rehab are randomly assigned to usual care, the app with self-guided content, or the app …

This study tests whether a special method to expand a new 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 optimized expansion meth…

This large trial tests whether the sedative dexmedetomidine can prevent long-term memory and thinking problems that often follow heart surgery. Researchers will give the drug to 2,400 adults aged 60 and older during and after their operation, then track their cognitive function f…

This study tests a program called Transition to Cardiac Rehabilitation (T2CR) for Veterans with heart disease who also have other health problems or frailty. The program starts in the hospital and continues at home, helping patients build skills and motivation to do cardiac rehab…

This study tests whether a cardiometabolic clinic can help obese adults with heart disease lose weight and improve health. Sixty participants will receive care from the clinic and be followed for 12 months. Researchers will measure weight loss, body mass index, and fat distributi…

This study tests an artificial intelligence program that analyzes heart rhythm data from a small, wearable patch to estimate how well the heart pumps blood. Researchers will compare the AI's results to standard ultrasound in 2,000 adults. If accurate, this could offer a simpler, …

This study is testing a special vest called HALD that records heart and lung sounds. Researchers want to see if the recordings are as accurate as what a doctor hears with a stethoscope. About 200 adults with or without heart or lung conditions will wear the vest during a clinic v…

This study is testing whether a simple, non-invasive sensor called photoplethysmography (PPG) — already found in many smartwatches — can accurately predict how well the heart pumps blood (ejection fraction) and other heart health measures. Researchers will have 500 adults wear a …

This trial is testing a digital stethoscope that uses artificial intelligence to detect clinically significant heart murmurs in emergency department patients. Researchers will enroll 300 adults with symptoms like chest pain or shortness of breath. The device records heart sounds …

This study tests whether giving fish oil through a vein during heart surgery can prevent a common complication called atrial fibrillation (irregular heartbeat) and help patients recover faster. About 550 high-risk adults having elective heart surgery will receive either fish oil …

This study at Mayo Clinic looks at how changes in the blood vessels of the lungs affect people with heart valve disease. Researchers will use echocardiograms during routine heart catheterization to measure these changes in 600 adults scheduled for valve procedures. The goal is to…

This study is observing 1,000 adults with multiple or mixed heart valve disease to learn more about how the condition progresses and how it is best managed. Researchers will use heart imaging and blood tests to find markers that predict outcomes. The goal is to create better guid…

This study looks at 82 people with severe aortic stenosis who need open-heart surgery to replace their aortic valve. Before surgery, each person gets a CT scan to measure the valve. During surgery, doctors also measure the valve with special tools. The goal is to see which method…

This study will use a new type of cardiac MRI to look at the heart's microscopic structure in 1,000 people—both healthy volunteers and those with various heart conditions. The goal is to see if this advanced imaging can detect early signs of heart damage better than standard test…

This study tests whether artificial intelligence (AI) can help cardiologists read echocardiograms (heart ultrasounds) more quickly and consistently. Researchers will give AI analysis to doctors in real time as they review heart images from 50 participants with valve disease. The …

This registry will follow 2,500 people who receive Abbott heart devices, such as implants for holes in the heart or replacement heart valves. The goal is to check how safe and effective these devices are when used in everyday hospital practice. Data will be collected from standar…

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

This study is following 4,000 people with heart valve disease to look for new substances in the body (called metabolites) that might be linked to the disease. Researchers hope to find better ways to predict who will get worse and understand why. No new treatments are being tested…
