Abstract

The common ostium of left and right inferior PVs is an extremely rare variant which was only reported in 16 cases undergoing catheter ablation. Thus, electrophysiologists should be careful about such an exremely rare PV variants for the safety and efficacy of ablation. Pre-procedural CTA is a valuable tool to decide on the ablation strategy in patients with such a very rare PV anomaly.
