Key result
RVOT ablation linked to ischemia-related VT driven by acute LAD occlusion.
Why the study?
Coronary artery injury is a rare complication of catheter ablation in the right ventricular outflow tract and acute myocardial ischemia usually causes polymorphic VT or ventricular fibrillation.
Case Report (n=1)
Highlights a rare but severe complication of RVOT catheter ablation, where acute LAD occlusion can provoke ischemia-related ventricular tachycardia.
RVOT ablation warrants vigilance for acute coronary injury; this case report leaves open optimal preventive strategies.
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.

Nakatani et al. (2020) conducted a case report in Ventricular tachycardia originating from the right ventricular outflow tract (n=1). Catheter ablation was evaluated on Acute coronary artery occlusion and ischemia-related ventricular tachycardia. Catheter ablation for ventricular tachycardia originating from the right ventricular outflow tract provoked ischemia-related ventricular tachycardias due to acute occlusion of the left anterior descending artery.
