Value of CT localization of the fossa ovalis prior to transseptal left heart catheterization for left atrial ablation

Abstract

This study demonstrates the feasibility of MDCT to localize the FO and aid TP. For patients undergoing left atrial ablation in whom MDCT imaging is undertaken pre-ablation, tagging the FO can be easily performed and is a novel tool for guiding transseptal catheterization without additional risk.
