Catheter-based radiofrequency (RF) ablation is an effective, well-established therapy for ventricular tachycardia (VT). However, a large number of patients still have recurrences, particularly those with substrates arising from intramural locations that are inaccessible through endo- or epicardial catheter approaches. Several unconventional ablation techniques have been proposed to treat RF-refractory VT, including transarterial coronary ethanol ablation and retrograde coronary venous ethanol ablation. We review the evidence regarding the mechanisms, procedural aspects, and alcohol ablation outcomes for ventricular arrhythmias.
