AORTIC VALVE STENOSIS

This study tested whether a common heart valve replacement procedure could be done safely without first stretching the valve with a balloon. Researchers compared the standard method (with balloon stretching) against a simpler method (direct valve placement) in 250 patients with s…

This study tested the Evolut PRO system, a replacement heart valve, in 638 patients with severe aortic valve stenosis who were at high or intermediate risk for open-heart surgery. The goal was to see how safe and effective the valve is in real-world hospital settings over five ye…

This study tested a program designed to reduce the waiting time for a critical heart valve procedure called TAVI. It combined online patient education tools with changes to hospital coordination. The goal was to see if this approach could get more patients their needed treatment …

This study tested whether automated alerts sent to doctors could help identify and treat patients with severe aortic stenosis or mitral regurgitation—two serious heart valve conditions. Over 2,100 patients were involved to see if these alerts led to more timely specialist visits …

This study tested a specific numbing injection, called a TAP block, to see if it could better control pain for patients undergoing a minimally invasive heart valve replacement (TAVI). Researchers compared the pain levels and medication needs of 50 patients who received the nerve …

This study tested whether a targeted nerve block, guided by ultrasound, could help manage pain in patients undergoing a minimally invasive heart valve replacement (TAVI). Researchers compared pain levels and the need for strong painkillers in 40 patients who either received the n…

This completed study aimed to understand how well standard heart ultrasound (echocardiography) can detect heart muscle scarring (fibrosis) in patients with severe aortic valve narrowing. Researchers analyzed existing data from 22 patients who had both ultrasound scans and small t…

This study tested whether two advanced heart scan techniques could better predict how patients do after a TAVI procedure to replace a narrowed aortic valve. Researchers followed 100 patients with severe aortic stenosis to see if these scans could more accurately forecast risks li…

This study looked at whether replacing a severely narrowed heart valve (aortic stenosis) could reduce scarring in the heart muscle. Researchers followed 86 patients, using special heart MRI scans before and one year after their valve replacement surgery. The goal was to see if th…

This study aimed to understand how aortic valve stenosis affects heart muscle stiffness. Researchers measured stiffness directly on the heart during surgery in 98 patients—some having valve replacement and others having bypass surgery. They used a special ultrasound technique to …
