Coronary arterial injury during right ventricular outflow tract ablation: Know your neighbors

Left anterior descending (LAD) coronary arterial injury is an underappreciated and rare consequence of ablation in the right ventricular outflow tract (RVOT). The authors present five cases of acute or subacute LAD injury after RVOT ablation. Most patients had fairly extensive ablation and two had coincident cardiac perforation. The patients reported also had a strikingly similar ECG morphology of their spontaneous ventricular arrhythmias. The authors’ report serves an important cautionary tale regarding ablation of intramural septal VAs.
