Why the study?
Left anterior descending coronary arterial injury is an underappreciated and rare consequence of ablation in the right ventricular outflow tract.
Right ventricular outflow tract ablation, particularly for intramural septal ventricular arrhythmias, carries a rare but important risk of left anterior descending coronary arterial injury.
Warrants vigilance for LAD injury during RVOT ablation; leaves open incidence, predictors, and prevention strategies.
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 This article is protected by copyright. All rights reserved.
