The primary effectiveness endpoint is the rate of effective LAA closure.
The rate of effective LAA closure defined as peri-device flow ≤ 5mm as demonstrated by TEE at the 45-day visit
45 days
The primary safety endpoint is the occurrence of pre-specified events between the time of implant and 7 days following the procedure or by hospital discharge, whichever is later.
Occurrence of one of the following events between the time of implant and 7 days following the procedure or by hospital discharge, whichever is later * All-cause death * Ischemic stroke * Systemic embolism * 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. Note: Percutaneous catheter drainage of pericardial effusions, snaring of an embolized device, thrombin injection to treat femoral pseudoaneurysm and minor nonsurgical treatments of access site complications are excluded from this endpoint
By hospital discharge or 7 days post-procedure (whichever is later)
