ABSTRACT
Coronary artery injury is a rare complication of catheter ablation in
the right ventricular outflow tract (RVOT). Furthermore, acute
myocardial ischemia usually causes polymorphic ventricular tachycardia
(VT) or ventricular fibrillation. We herein describe a case in which
catheter ablation for VT originating from the RVOT provoked
ischemia-related VTs due to acute occlusion of the left anterior
descending artery.
