Head-to-head Comparison of Single Versus Dual Antiplatelet Treatment Strategy After Percutaneous Left Atrial Appendage Closure: a Multicenter, Randomized Study

Summary

The study will perform a randomized, head-to-head comparison between SAPT (aspirin) and DAPT (aspirin plus clopidogrel) after percutaneous LAA closure with implantation of the Amulet device (AbbottTM, Abbott Park, Illinois, US) in patients with AF. Primary outcome measure will be a net composite endpoint at 6 months including all-cause death, DRT, clinically relevant bleeding complications and ischemic events. The SAPT arm will receive aspirin alone up to 6 months, while the DAPT arm will receive DAPT for 3 months and then aspirin alone. Thus, between 3- and 6-month follow-up both groups will be given aspirin alone.
