Non-valvular Atrial Fibrillation Clinical Trial
Official title:
Observe the Safety and Effectiveness of the WATCHMAN FLX™ Left Atrial Appendage Closure (LAAC) Device for Subjects With Non-valvular Atrial Fibrillation to Reduce the Risk of Stroke in Hong Kong Area
The primary objective of this study is to observe the safety and effectiveness of the WATCHMAN FLX™ Left Atrial Appendage Closure (LAAC) Device for subjects with non-valvular atrial fibrillation to reduce the risk of stroke in Hong Kong area.
This study is a prospective, non-randomized, multi-center observational study. The primary Effectiveness Endpoint is the occurrence of non-effective LAA closure defined as any peri-device flow > 5mm demonstrated by TEE/CT/MRI at First Follow-up.The primary safety endpoint is the occurrence of one of the following events between the time of implant and within 7 days following the procedure or by hospital discharge, whichever is later: all-cause death, ischemic stroke, systemic embolism, or device or procedure related events requiring open cardiac surgery or major endovascular intervention such as pseudoaneurysm repair, AV fistula repair, or other major endovascular repair. Secondary effectiveness endpoint is the occurrence of ischemic stroke or systemic embolism at 12 months from the time of implant. ;
