Why the study?
Left anterior descending coronary arterial injury is an underappreciated and rare consequence of ablation in the right ventricular outflow tract.
RVOT ablation carries a rare but important risk of LAD coronary arterial injury, highlighting the need for caution during ablation of intramural septal ventricular arrhythmias.

Potential LAD injury after RVOT ablation warrants clinical vigilance; case series leaves open questions on incidence and prevention.
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.
