Trial Compares Two Devices Used For Percutaneous Left Atrial Appendage Closure
Cardiovascular Research Foundation (CRF)SWISS-APERO is the first randomized clinical trial comparing Amulet with the new generation Watchman FLX device in terms of residual left atrial appendage (LAA) patency after percutaneous LAA closure (LAAC) as evaluated by 45-day cardiac computed tomography angiography (CCTA). The study showed that the two devices achieve a similar rate of LAA occlusion at 45 days but through different mechanism. Furthermore, Amulet as compared with Watchman FLX was associated with higher procedural complications but similar clinical outcomes at 45-days.
