The left atrial appendage (LAA) has been termed "our most lethal human attachment."(1) Excision or exclusion of the LAA is a component of most operations to treat atrial fibrillation (AF) and reduces late thromboemboli in patients with AF undergoing mitral valve surgery.(2) However, surgical technique affects results, and incomplete Suture ligation increases risk of thromboembolism.(2,3) We report our experience with stapled excision and pericardial buttressing of the LAA.
