Coronary Venous Mapping and Ablation for Ventricular Tachycardia.

Coronary venous mapping and ablation can be an effective strategy in targeting ventricular arrhythmias that arise from intramural or epicardial sites of origin. We discuss the case of a patient with ischemic cardiomyopathy referred to our center for index ventricular tachycardia ablation after receiving multiple shocks from his implantable cardioverter-defibrillator who underwent coronary venous mapping and ablation as an adjunct to endocardial ventricular tachycardia ablation.
