This article is a presentation of direct surgery for ventricular tachycardia in patients undergoing surgical ventricular restoration. The procedure includes a non-electrophysiologically guided subtotal endocardiectomy and cryoablation in addition to endoventricular patch plasty of the left ventricle. Coronary artery bypass surgery and mitral valve repair are performed concomitantly as needed. In our experience, this procedure yielded a 90% success rate in terms of freedom from spontaneous ventricular tachycardia, with an early mortality rate of 3.8%. Perioperative considerations and a short overview of the literature are presented.
