Overview
Brief Summary
To evaluate the safety and efficacy of using Microport CardioAdvance Left Atrium Appendage Closure for preventing stroke in Non-valvular atrial fibrillation (NVAF) patients who have contraindications for long-term anti-coagulation. And to support registration approval from National Medical Products Administration (NMPA).
Detailed Description
SAFE-PROTECT trial is composed of Roll-in group, small-size group and RCT group. This trial is planned to conduct in about 20 sites from China. Roll-in group plans to enroll at most 3 subjects each site to implant experimental device for exploration and observation. RCT group plans to enroll no less than 210 subjects who meet the inclusion/exclusion criteria, and 1:1 randomly allocated to experimental arm or comparator arm.
