AORTIC STENOSIS

This study tested a device called ShortCut that splits the leaflets of a failing artificial heart valve before placing a new valve inside it. The goal was to prevent the old leaflets from blocking the coronary arteries, which can cause a heart attack. Eight people at risk for thi…

This study tested whether blood thinners (DOACs) work better than aspirin to prevent valve damage and serious heart problems after a less invasive aortic valve replacement (TAVI). 360 patients aged 65-80 were randomly assigned to take either a DOAC or aspirin daily. The main goal…

This study tested whether a new way of processing tissue for Edwards heart valves is safe and works well. 777 adults who needed a new aortic or mitral valve took part. Researchers checked for valve problems like wear or calcification over about a year, and will follow patients fo…

This pilot study tested whether colchicine, an anti-inflammatory drug, can slow the buildup of calcium in the aortic valve. 24 adults with mild-to-moderate aortic stenosis were randomly assigned to take colchicine or a placebo for 6 months. The study measured changes in valve cal…

This study compared two different artificial heart valves (Sapien and Myval) used in a procedure called TAVI to replace a narrowed aortic valve. Over 1,000 patients were randomly assigned to receive one of the two valves. The goal was to see which valve led to fewer major heart p…

This study tested two new heart valves (Portico and Navitor) in 30 Indian patients with severe aortic stenosis, a condition where the heart's main valve narrows. The goal was to see if the valves are safe and work well. Researchers tracked complications and heart function for up …

This study tested a new tool called TELLTALE designed to safely cut a heart tissue flap during a valve replacement procedure (TAVR). In some cases, this flap can block blood flow to the heart, which is often fatal. The trial involved 90 adults at high risk of this complication. R…

This study tested a procedure called left atrial appendage occlusion (LAAO) against standard blood-thinning medications in 81 people with atrial fibrillation who were also getting a new heart valve (TAVI). The goal was to see if LAAO could prevent strokes and bleeding better than…

This study tested a new heart valve, the SAPIEN 3, in 58 Chinese patients with severe aortic stenosis who were at high risk for traditional open-heart surgery. The valve was implanted using a thin tube through a blood vessel, avoiding the need for open surgery. The main goal was …

This study looked at 15 patients with a rare heart condition called wild-type transthyretin amyloid cardiomyopathy (ATTRwt) who also had signs of aortic stenosis. Researchers used dobutamine stress echocardiography—a test that uses a drug to make the heart pump harder while imagi…

This study tested a new device called VIVHEART EasyCross™ in 20 people undergoing transcatheter aortic valve replacement (TAVR). The device uses a basket-like tip to center itself in the artery, making it easier and quicker to guide a wire through the heart valve. The goal was to…

This study looked at whether having a nurse talk with patients before and after a heart valve procedure could improve care. About 194 people took part. The nurses helped prepare patients and checked on them afterward, either by phone or in person. The goal was to see if this extr…

This study tested two different methods of closing the main leg artery after a minimally invasive heart valve replacement (TAVR). One method used two small stitch-like devices, the other used one stitch device plus a plug. The goal was to see which approach caused fewer bleeding …

This study looked at how certain heart devices change a blood-clotting protein called von Willebrand factor. Researchers studied 500 adults with heart failure or aortic stenosis who received a mechanical heart pump or a valve replacement. The goal was to understand when these pro…

This study looked at 81 people with mild memory problems who were getting a heart valve replacement (TAVR). Researchers tested their thinking and memory with a 5-minute quiz before the procedure and again 30 days and 6 months after. The goal was to see if fixing the heart valve c…

This study collected blood and tissue samples from 91 adults with aortic valve disease to look for genetic differences that might explain why some develop aortic aneurysms. Researchers compared gene activity in people with bicuspid valves, tricuspid valves, and healthy controls. …

This study watched 258 people getting a new heart valve (TAVR) to see how a device called MANTA closes the large hole in the leg artery. The goal was to check for bleeding problems and how fast the artery seals. No new treatments were tested; researchers just collected real-world…

This study looked at 116 patients with severe aortic stenosis and moderate coronary artery disease who were scheduled for valve replacement. Researchers measured blood flow in the heart arteries before, right after, and 6 months after valve replacement to see how the procedure af…
