Abstract

Highlights: We reviewed 185 PVC catheter ablation cases and identified 17 in which PVCs were successfully ablated in the aortic cusps. The MDI measured 0.53 ± 0.10 (median 0.50, IQR 0.47–0.60). In all (100%) cases MDI was > 0.40 and in 7 (41%) cases it was > 0.55. Pseudo-delta wave was absent in all but one PVC PVC origin in the aortic cusps should be considered along with the epicardium when MDI is in the vicinity of 0.55.
