Congenital left atrial appendage aneurysm: Atypical presentation

Mehdi Bamous et al. Ann Pediatr Cardiol. 2017 Sep-Dec.

Abstract

Congenital left atrial appendage aneurysm is a rare condition caused by dysplasia of the atrial muscles. We report a case of a 14-year-old boy, with a 5-month history of cough and in sinus rhythm. Transthoracic echocardiography and computerized tomographic angiography confirmed the aneurysm of the left atrial appendage which was resected through median sternotomy on cardiopulmonary bypass. This case is presented not only for its rarity but also for its atypical clinical presentation.

Keywords: Aneurysmectomy; congenital heart disease; left atrial appendage aneurysm.
