Abstract

Introduction: Evidence for the effectiveness of surgical electrophysiological therapy for malignant ventricular tachycardia (VT) after myocardial infarction is lacking. Methods and Results: We report a case of a 50-year-old man with VT caused by left ventricular aneurysm (LVA). Unipolar radiofrequency ablation (RFCA) failed to treat VT. Nonetheless, bipolar RFCA forcep guided by CARTO mapping was used to ablate the LVA and peripheral myocardium during traditional surgery. There were no postoperative complications, and 1-year follow-up showed no malignant VT occurred in 24-hours. Conclusion: Bipolar RFCA assisted by CARTO mapping was an effective surgical electrophysiological therapy for refractory VT caused by LVA.
