Successful elimination of recurrent ventricular tachycardia by epicardial ablation over coronary artery supplying postinfarction aneurysm

Intracavitary thrombus: A hidden piece of puzzle that may influence the outcome of ablation for ventricular tachycardia

“…If the critical portion of the arrhythmogenic substrate is inaccessible and protected by thrombus, alternative strategies can be considered. Besides epicardial ablation of the substrate, we described the ablation over the epicardial coronary artery supplying the aneurysm 9 . Alternatively, intramural venous ethanol infusion could be used 10 .…”
