This study follows 225 adults who have the Ross procedure, a surgery that replaces a diseased aortic valve with the patient's own pulmonary valve. Researchers will track survival, hospital readmissions, and need for repeat surgeries over 1, 5, and 10 years. The goal is to confirm…

This study tests a special balloon that uses shockwaves to crack calcium buildup in the iliac arteries, making it possible to deliver large aortic stents. About 40 adults with severe aortic disease and hardened arteries will be enrolled. The goal is to see if this approach is saf…

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 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 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 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 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 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…

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 study is a registry that will follow up to 2,700 people who have received or will receive a Medtronic heart valve product during surgery. The goal is to monitor the long-term safety and performance of these devices by identifying any unexpected problems or trends. Participan…
