Resection of a Giant Left Atrial Appendage Aneurysm via Limited Thoracotomy

A left atrial appendage aneurysm is a rare cause of atrial arrhythmia in a young adult. Resection of the aneurysm is uniformly recommended in order to prevent thromboembolism and stroke. In patients without evidence of clot within the aneurysm, operative resection via a limited thoracotomy provides a safe and effective alternative to median sternotomy with cardiopulmonary bypass.
