Abstract:
The left atrial appendage occlusion (LAAO) by endocardial suture is sometimes inadequate and thrombogenic with uncertain electrical competence. Moreover, epicardial LAAO clip placement through the transverse sinus can be technically challenging during minimally invasive atrioventricular valve surgery. Here, we describe our new endoscopic technique via an anterior access pathway in 5 patients with concomitant atrial fibrillation using an epicardial clip device (AtriClip Pro 1 or AtriClip Pro 2, AtriCure, Mason, OH, USA) for LAAO. The LAAO was successful in all patients without residual perfusion and surgical complications. Epicardial LAAO by clip via the anterior access pathway represents a novel and feasible endoscopic technique for minimally invasive atrioventricular valve surgery.
