The impact of transcatheter aortic valve replacement on changes of coronary computed tomography-derived fractional flow reserve.

ABSTRACT:

Background

The effect of transcatheter aortic valve replacement (TAVR) on changes of computed tomography-derived fractional flow reserve (CT-FFR) values was controversial. Thus, we aimed to identify the impact of TAVR on changes of CT-FFR values, plaque characteristics, and the associated clinical impact.

Methods

This single-center observational study included 39 consecutive patients with severe aortic valve disease undergone TAVR between August 2019 and April 2023, whom were performed with preoperative and postoperative coronary CT angiography (CCTA). The computation of CT-FFR and plaque characteristics was performed by an independent central core laboratory.

Results

Each patient underwent CCTA and CT-FFR assessment without encountering any complications. Notably, bo
