Left Atrial Appendage Closure as Secondary Prevention of Atrial Fibrillation-related Embolic Events

A Prospective, Multicenter Clinical Study of Percutaneous Left Atrial Appendage Closure as Secondary Prevention of Atrial Fibrillation-related Embolic Events in Patients With Atrial Fibrillation


Sponsor

Lifetech Scientific (Shenzhen) Co., Ltd.

Enrollment

579 participants

Start Date

Nov 12, 2020

Study Type

OBSERVATIONAL

Conditions

Summary

This clinical study is a prospective, multi-center, non-interventional study designed to investigate the safety and effectiveness of percutaneous LAA appendage closure by using LAmbre™ Left Atrial Appendage Occluder System. 579 patients with valvular AF complicated with previous AF-related embolic events (including ischemic stroke, TIA and systemic embolism) were enrolled at about 20 study sites nationwide. The baseline data, operation process and relevant follow-up information of subjects were recorded at 7 months after operation or before discharge and at 1, 3, 6, 12 and 24 months after operation.
