Heart pouch showdown: which device best prevents strokes?
NCT ID NCT07260474
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study compares two medical devices (Amplatzer Amulet and LAmbre) used to close a small pouch in the heart called the left atrial appendage. The goal is to reduce stroke risk in people with an irregular heartbeat (atrial fibrillation) who are at high risk for bleeding from blood thinners. About 200 participants will be randomly assigned to receive one of the two devices, and researchers will check how well the pouch is sealed and track safety outcomes for 90 days.
