Ventricular reconstruction with vascular prosthesis after aneurysmectomy: Ability to defibrillate and utilize the internal cardioverter defibrillator

Abstract

Adjunct surgical procedures for patients with malignant ventricular tachyarrhythmias who require the automatic internal cardioverter defibrillator include aortocoronary artery bypass graft surgery, valvular repair or replacement, subendocardial resection, and aneurysmectomy. Ventricular reconstruction and its compatibility with the AICD are described in a 64-year-old man who required treatment of refractory ventricular tachycardia as well as resection of a large anteroapical aneurysm. Reconstruction using a dacron patch preserved left ventricular geometry but did not adversely affect the ability to defibrillate and allowed successful utilization of the automatic defibrillator.
