Ventricular tachycardia ablation in the post‐surgical patients is complicated by difficult epicardial access. Endocardial‐only ablation may lead to failure which can be prevented by mapping and ablating inside the coronary venous system. Radiofrequency ablation inside the coronary venous system is dependent on anatomical and biophysical factors. Herein we report a ventricular tachycardia case necessitating bipolar ablation between the middle cardiac vein and the left ventricular endocardium. [ABSTRACT FROM AUTHOR]
