The Primary Safety Endpoint of LAA Closure

The primary effectiveness end point which is the rate of effective LAA closure at one year was achieved in all patients. The occurrence of any one of these events between the time of implant and within seven days following the procedure occurred in only two patients or 0.5%. Nearly all patients, 96% were able to discontinue their oral anticoagulation at 45 days after the TE showed that there is adequate closure of the left atrial appendage. One percent continued their anticoagulating because of inadequate seal. This is quite comparable if not better to the prior watchman trials in terms of oral anticoAGulation discontinuation rate.
