Left atrial appendage closure with WATCHMAN in Asian patients: 2 year outcomes from the WASP registry.

Background: Left atrial appendage closure is a non-pharmacological alternative for stroke prevention in high-risk non-valvular atrial fibrillation patients, but has not been widely studied in Asian patients. The prospective WASP registry assessed real-world outcomes for patients undergoing WATCHMAN implant in the Asia-Pacific region.

Methods: Data were collected from consecutive patients across 9 centres.
