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