Stroke prevention in nonvalvular atrial fibrillation: Thoracoscopic left atrial appendage closure with or without surgical ablation.

ABSTRACT:

Objectives

Totally thoracoscopic left atrial appendage closure (TT-LAAC) with or without the MAZE procedure is an LAA management technique that prevents cardioembolic events by closing the LAA in patients with atrial fibrillation (AF). Additionally, it facilitates rhythm control with a concurrent a mini-maze procedure. Here we present TT-LAAC outcomes without the MAZE procedure (TT-LAAC) and with the maze procedure (TT-MAZE).

Methods

LAAC and/or bilateral pulmonary vein isolation were performed under complete thoracoscopy, with ablation performed using a radiofrequency device. Patients undergoing both LAAC and ablation were classified as TT-MAZE, whereas those undergoing only closure were classified as TT-LAAC. Successful closure was defined as a stump <10 mm as assessed via
