Aortic stenosis

This study tested a new device called the ACURATE neo2, which replaces a narrowed heart valve without open-heart surgery. About 1,900 people with severe aortic stenosis received either the new device or a standard one. The goal was to see if the new device is safe and works as we…

This trial compares two different TAVI devices (Evolut FX and Sapien 3 Ultra Resilia) used to replace a narrowed heart valve in people with aortic stenosis. About 1,346 patients will be randomly assigned to get one device or the other. Researchers will track deaths, strokes, valv…

This early study tests a new device called the DurAVR™ heart valve in 15 people aged 65 and older with severe aortic stenosis, a condition where the heart's aortic valve becomes narrowed. The valve is implanted through a catheter (TAVR) without open-heart surgery. The main goals …

This trial studies nearly 1,000 people with severe aortic stenosis and blocked coronary arteries who need both a valve replacement (TAVI) and artery stenting (PCI). Researchers want to see if doing the stenting before or after the valve replacement leads to fewer deaths, heart at…

This study is testing a new surgical heart valve (Model 400) in over 1,300 people with aortic valve disease. The valve is designed to replace the damaged aortic valve and improve blood flow. Researchers are checking how safe the valve is and how well it works over one year, looki…

This study compares two ways to replace a narrowed heart valve in elderly patients (65+) who have a small valve opening. One method is less invasive (TAVR, through a tube in an artery), the other is open-heart surgery. The goal is to see which approach gives better blood flow and…

This study tests a new, less invasive heart valve (SAPIEN 3) for people with severe aortic stenosis who are at low risk for standard surgery. About 1,000 participants will be randomly assigned to get the new valve or traditional open-heart surgery. The goal is to see if the new v…

This study compares two ways to replace a narrowed heart valve in people with a bicuspid aortic valve (a common birth defect). One method is transcatheter aortic valve replacement (TAVR), a less invasive procedure using a tube inserted through a blood vessel. The other is traditi…

Researchers test whether an AI algorithm called AK-AVS can spot moderate-to-severe aortic stenosis, a narrowing of the heart's aortic valve, in older adults who have not been diagnosed. The study reviews about 4,000 routine electrocardiograms (ECGs) already collected during prima…

This study tests whether artificial intelligence (AI) can spot a serious heart valve condition called aortic stenosis using portable, non-invasive devices. Researchers will enroll 410 adults aged 70 and older during routine primary care visits. The goal is to see if AI-powered an…

This study follows 200 adults in Western Denmark who are having a transcatheter aortic valve implantation, a procedure to replace a narrowed heart valve. Researchers will measure quality of life before the procedure and at follow-up using a standard questionnaire. They will also …

This study will enroll 210 adults aged 65 and older with early aortic stenosis (a heart valve narrowing) to see if an artificial intelligence tool can better predict how fast the disease worsens. Participants will have standard echocardiograms, and researchers will compare the AI…

This study follows 200 people who had a heart valve replacement (TAVI) to see how often they experience heart rhythm problems in the weeks after the procedure. Participants wear a portable ECG monitor for up to 4 weeks after leaving the hospital. The goal is to learn how common t…

This study enrolls 800 people with severe aortic stenosis who are scheduled for a TAVI procedure (a less invasive heart valve replacement). Researchers will compare participants from different countries using CT scans of the heart and blood tests to measure inflammation. The goal…

This study looks at how well two types of replacement heart valves (balloon-expandable vs. self-expanding) work in Asian patients with a naturally small aortic valve opening. Researchers will track 31 people for one year to see which valve type leads to fewer complications and be…
