Key result
RVOT catheter ablation triggers ischemia-related VT via 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)
Catheter ablation in the RVOT can rarely cause acute LAD occlusion leading to ischemia-related ventricular tachycardia.
Alerts to rare LAD occlusion risk in RVOT ablation; single case leaves open incidence and 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 in the right ventricular outflow tract was evaluated on Acute occlusion of the left anterior descending artery provoking ischemia-related VTs. Catheter ablation for ventricular tachycardia originating from the right ventricular outflow tract provoked ischemia-related VTs due to acute occlusion of the left anterior descending artery.
