Blood thinner comparison after left atrial appendage closure
Part of Heart & circulation clinical trials.
This study compares two approaches after a left atrial appendage closure (LAAC) procedure: taking no blood thinner versus taking just one antiplatelet medication. It aims to see which option is safer for people with atrial fibrillation who are at risk for bleeding.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You have atrial fibrillation that is not caused by a heart valve problem.
- You have a CHA2DS2-VA score of 2 or higher (a measure of stroke risk).
- You have already had a successful left atrial appendage closure with the Watchman FLX Pro device.
- You are not already on blood thinners for reasons other than atrial fibrillation.
- You have not had a stroke, heart attack, or major surgery within the last 30 days.
- You are not pregnant, breastfeeding, or planning to become pregnant.

This trial tests whether patients who receive a special device to close a hole in the heart (to prevent stroke from irregular heartbeat) can safely take fewer blood-thinning medications afterward. The study compares taking a standard blood thinner for 3 months versus taking aspirin only, to see which approach works best with fewer bleeding risks.
This study is for people who had a stroke despite taking blood thinners for atrial fibrillation. It tests if adding a procedure to close the left atrial appendage (a small pouch in the heart) to your blood thinner is better than just taking the blood thinner alone to prevent another stroke.
This trial compares a procedure that blocks a heart blood-choke point (the left atrial appendage) versus taking blood thinners by mouth. It is for people with atrial fibrillation who have had a brain bleed and may be safer avoiding long-term blood thinners.
This study looks at whether a lower-dose blood thinner works as well as the usual recommended anti-clot treatment after a procedure that closes off the heart’s left atrial appendage. It may help reduce bleeding risk while still preventing dangerous blood clots.
This study compares two ways of closing a small pouch in the heart (the left atrial appendage) to help prevent strokes in people with atrial fibrillation (an irregular heartbeat). One method is less invasive, and the study aims to see if it is as safe and effective as the standard approach.
This study tests whether it is safe and effective to use just one blood thinner (aspirin or clopidogrel) for a short time after getting a LAmbre device implanted to close off a heart pouch that can cause strokes. It is for people with atrial fibrillation who cannot take standard blood thinners long-term.
