This study tests a new surgical technique called the 'Y incision' for people with a small aortic annulus (the ring where the heart valve sits) who need aortic valve replacement. The standard methods often limit how large a replacement valve can be placed, which can lead to poor b…

This study tests an artificial intelligence (AI) model that can screen for heart valve disease using standard chest CT scans that people already get for other reasons. The goal is to see how well the AI catches moderate-to-severe cases without needing extra tests or contrast dye.…

This study investigates whether a blood test measuring clotting and clot-busting markers can predict complications in patients undergoing aortic valve replacement. Researchers will follow 750 adults with aortic stenosis who receive either surgical or catheter-based valve replacem…

This study tests whether artificial intelligence can analyze standard ultrasound images of the heart to measure calcium buildup on the aortic valve. If accurate, this could help doctors diagnose severe aortic stenosis without the extra cost and radiation of a CT scan. The study w…

This study tests whether a portable electronic stethoscope, combined with machine learning, can accurately detect valvular heart disease. About 125 people with and without the condition will use the device and also receive standard heart tests. Researchers will compare the device…

This study explores whether kinocardiography (KCG), a portable device that measures chest vibrations from heartbeats, can diagnose aortic valve disease and thoracic aortic aneurysm. Researchers will compare KCG readings with standard imaging in 180 adults, including those with an…

This study is testing whether a small implantable heart monitor (Reveal LINQ) can detect serious heart block in people who develop a new electrical problem (left bundle branch block) after having their aortic valve replaced (TAVI). About 80 participants will get the monitor and b…

This study is testing whether having a dental checkup before heart valve surgery can prevent serious complications like infection of the heart lining, repeat surgery, or death. About 1,300 adults scheduled for valve surgery will be randomly assigned to either get a dental screeni…

This study is reviewing medical records from 5,000 heart and blood vessel surgery patients to find factors that influence recovery and survival. Researchers are looking at data from 2001 to 2013 to identify what leads to complications or death after surgery. The goal is to improv…

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 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 is tracking 500 people who receive the INSPIRIS RESILIA aortic valve during surgery. Researchers will measure how well the valve works by checking blood flow and leakage over time. The goal is to see how the valve performs in everyday medical practice.

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 tracks 300 adults with aortic disease to measure how their condition impacts quality of life, fatigue, mental health, and ability to work. Researchers will use questionnaires over 12 months to gather data. The goal is to better understand these challenges and help desi…

This study is creating a large biobank of blood, DNA, plasma, and tissue samples from 15,000 people with and without heart and aortic diseases. Researchers will use this information to better understand conditions like aortic aneurysm, heart failure, and bicuspid aortic valve. Th…
