Transmitral approach to monopolar radiofrequency ablation of inferior papillary muscle for refractory ischemic ventricular tachycardia.
Despite the proven effectiveness of antiarrhythmic drugs and automated implantable cardioverter-defibrillators for ischemic ventricular arrhythmias, ablative procedures still play a major role. Herein, we report the cases of 2 patients who had malignant ventricular arrhythmias secondary to ischemic heart disease. The arrhythmias were treated intraoperatively by means of surgical ablation through a transmitral approach.
