Heart device study shows promise for stroke prevention in southeast asia
NCT ID NCT05687591
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested a device called Amplatzer Amulet that closes a small pouch in the heart (left atrial appendage) in people with atrial fibrillation. The goal was to see if it safely reduces stroke risk without long-term blood thinners. 104 adults at high stroke risk took part across multiple centers in Southeast Asia. Researchers checked for device problems, leaks, strokes, and bleeding over one year.
