This study at Mayo Clinic is testing whether artificial intelligence can help standard electrocardiograms (ECGs) detect two common heart valve problems: aortic stenosis and diastolic dysfunction. Researchers will enroll 2000 adults aged 60 and older who are already scheduled for …

This study compares two heart imaging methods—echocardiography (ultrasound) and cardiac MRI—to see which measures heart valve disease more accurately. Researchers will enroll 200 adults with suspected moderate or severe valve problems. The goal is to improve how doctors assess va…

This study tests an artificial intelligence (AI) tool to help doctors accurately diagnose severe low-gradient aortic stenosis, a heart valve condition that can be hard to identify. About 300 adults with suspected disease will have their standard echocardiograms analyzed by the AI…

This study tests whether applying mild electrical stimulation to specific acupoints before anesthesia can help maintain stable blood pressure during TAVR heart valve surgery. Researchers will compare two different stimulation frequencies in 150 adults aged 60 and older. The goal …

This study tests whether using shockwave therapy on the leg artery before a TAVR heart valve procedure can reduce bleeding and other complications. It involves 100 adults with severe aortic stenosis and heavily calcified arteries. The goal is to make the procedure safer by prepar…

This study investigates why some people with moderate aortic valve stenosis get worse while others remain stable. Researchers will analyze immune system markers and detailed heart images from about 938 participants to find patterns that predict disease progression. The goal is to…

This study will follow 300 people with aortic stenosis who are scheduled for a TAVI procedure to replace their heart valve. Researchers will use heart scans, blood tests, and checkups to measure how the heart's condition changes over time. The goal is to better understand short- …

This study is collecting blood samples and quality-of-life questionnaires from 125 people with aortic stenosis, a heart valve condition. Researchers want to find biological markers (biomarkers) that could signal inflammation or scarring in the heart before symptoms appear. The go…
