Cryoablation of incessant ventricular tachycardia - Case report and long-term follow-up

We report the case of a 52-year-old man who had incessant ventricular tachy cardia despite treatment with antiarrhythmic agents. Placement of an implan table cardioverter/ defibrillator, radiofrequency ablation, and antitachyca rdia pacing were ineffective. He underwent intraoperative arrhythmia mappin g and cryoablation at our institution. Eighteen months later, he remained f ree of arrhythmia. He was in New York Heart Association functional class II with an ejection fraction of 30%.
