Key result
Epicardial ablation successfully abolished exercise-induced ventricular tachycardia in 3 treated patients with normal coronary arteriograms and left ventricular aneurysms.

Does epicardial ablation prevent VT recurrence in patients with normal coronary arteriograms and left ventricular aneurysm presenting with exercise-induced VT?
Exercise-induced VT with RBBB morphology in patients with normal coronaries and LV aneurysm may have a subepicardial substrate amenable to epicardial ablation.
Ouyang et al. (2003) conducted a case report in Ventricular tachycardia (n=4). Epicardial ablation was evaluated on Abolition of ventricular tachycardia. Epicardial ablation successfully abolished exercise-induced ventricular tachycardia in 3 treated patients with normal coronary arteriograms and left ventricular aneurysms.
