Summary

This study adapted a prospective, multicenter single-group objective performance criteria design. A total of 163 patients with non-valvular atrial fibrillation were enrolled in the clinical trial，follow up were scheduled in 7 days, 45 days, 6 months, 12 months, 2 years, 3 years, 4 years and 5years after procedure.

DEVICE

SeaLA™ left atrial appendage occluder

1. Guided by esophageal ultrasound (TEE) and angiography, the diameter of the left atrial appendage anchoring zone and the longest depth of the left atrial appendage were measured to determine the appropriate size of the left atrial appendage occluder. 2. Maintain Activated Clotting Time (ACT) greater than 250 seconds after atrial septal puncture to the completion of the entire procedure. 3. Before the plugging device is released, confirm whether there is a residual peri-device leak, and if there is a residual peri-device leak, consider retracting the occluder to reposition the release or retract the occluder to choose a larger size occluder to re-occlusion. If ultrasound confirms residual peri-device leak greater than 5 mm, do not release and implant the left atrial appendage occluder. 4. Before and after release, confirm the position and stability of the occluder under ultrasound (TEE), and confirm that the occluder completely occludes the left atrial appendage.
