Brief Summary:
Percutaneous left atrial appendage closure (LAAC) is an effective strategy for stroke prevention in patients with non-valvular atrial fibrillation (NVAF). Standard procedure requires general anesthesia, transesophageal echocardiography (TEE) guidance. With the experience accumulation, LAAC can be successfully completed in many centers under local anesthesia, the guidance of X-ray and transthoracic echocardiography (TTE), also known as minimalist procedure. Our center was one of the earliest to carry out minimalist procedure worldwide. At present, expert consensus suggests that minimalist procedure is feasible in experienced centers, but the relevant evidence is insufficient. Some single-arm studies have shown that minimalist procedure is safe and effective. However, there is currently a lack of direct evidence to compare the strengths and weaknesses of these two LAAC procedures. The goal of the study was to compare the effectiveness and safety of minimalist procedure and standard procedure for LAAC in patients with NVAF.
Detailed Description:
This is a prospective, randomized, controlled, multi-center clinical study designed to compare the safety and efficacy of minimalism transcatheter LAAC versus standard transcatheter LAAC in NVAF patients. The study aims to enroll approximately 200 NVAF patients requiring transcatheter LAAC at 20 to 30 research centers in China. All eligible patients who sign the informed consent form will be randomly assigned to either the minimalism transcatheter LAAC group or the standard transcatheter LAAC group in a 1:1 ratio. The study will record preoperative baseline information and follow-up data at 7 days post-Procedure or discharge, and at 2, 6, and 12 months post-Procedure, to explore the incidence of procedure-related complications and peridevice leak ≤5mm between the two groups.
