A novel technique of repair of congenital left atrial appendage aneurysm using bovine pericardial patch: A video presentation

Abstract

Because of its rarity and association with life threatening complications like supraventricular arrhythmias, systemic embolization, congestive cardiac failure, prompt recognition of congenital left atrial appendage aneurysm is important in patients with an enlarged cardiac silhouette and a prominent convex bulge of the left upper cardiac border without carinal widening. We report here-in a new technique of resection of the congenital left atrial appendage aneurysm and anatomical reconstruction using a bovine pericardial patch under cardiopulmonary bypass, permitting us to avoid undersizing and deformation of the left atrium.
