Intraoperative electro-anatomical mapping and beating heart ablation of ventricular tachycardia

Ann Thorac Surg. 2006 Sep;82(3):1091-3. doi: 10.1016/j.athoracsur.2005.12.042.

Abstract

In most cases ventricular tachycardia is responsive to antiarrhythmic drug therapy. If antiarrhythmic drugs fail, then percutaneous, endocardial ablation guided by electro-anatomical mapping is usually curative. Occasionally neither of these therapies is successful and surgical ablation is required. Challenges encountered in surgical ablation include application of reliable intraoperative real-time electro-anatomical mapping to identify the focus of ventricular tachycardia and the need for technology that enables ablation on the beating heart. We present a case demonstrating the feasibility of surgical cryoablation of ventricular tachycardia arising from the right ventricle using intraoperative real-time epicardial and endocardial electro-anatomical mapping and argon-based cryoablation.
