Several techniques, such as bipolar ablation, irrigated needle ablation catheter, and retrograde coronary venous ethanol ablation have been suggested. Transarterial coronary ethanol ablation (TCEA) can also be effective. We present a case series of TCEA guided with preprocedural imaging to correlated coronary arteries and the intramural substrate.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods and Results<\/jats:title><jats:p>We present three consecutive patients with previous RF of septal VT (100% male; age, 72.6 \u00b1 11.01 years; two patients with hypertrophic cardiomyopathy, one with mechanical aortic valve prosthesis) that underwent TCEA. Cardiac magnetic resonance was performed in two patients and cardiac CT in all patients. Correlation of septal arteries with intramural substrate was analyzed before the procedure so TCEA was attempted according to this analysis. After last TCEA (6.3 \u00b1 2.08 months) the VT burden was reduced in all patients (sum of all implantable cardioverter\u2010defibrillator therapies [antitachycardia pacing and shock] before and after TCEA, 15.8 \u00b1 3.73 vs 0.97 \u00b1 0.63 therapies\/month; <jats:italic>P<\/jats:italic>\u2009=\u20090.02).
