Fistulous pseudoaneurysm complicating surgical accessory pathway interruption for Wolff-Parkinson-White syndrome.

Abstract

Pseudoaneurysms of the left ventricle are unusual operative complications that have commonly been associated with replacement of the mitral valve. In this report, we describe a 31-year-old man who was referred to our institution because of atypical chest pain. He had previously undergone three operations for ablation of an accessory pathway because of Wolff-Parkinson-White syndrome. A pseudoaneurysm of the left ventricle was noted on transesophageal echocardiography, biplanar left ventriculography, and ultrafast cine computed tomography of the heart. Elective surgical repair was successful. Although rare, this case demonstrates an unusual but potentially serious complication of surgical treatment of Wolff-Parkinson-White syndrome.
