Transcatheter aortic valve replacement in patients with preoperative ascending aortic diameter ≥45 mm.

ABSTRACT:

Background

Current indication for concomitant replacement of ascending aorta (AA) in patients undergoing surgical aortic valve replacement is that AA diameter exceeds 45 mm. However, the impact of AA dilation (≥45 mm) in patients undergoing transcatheter aortic valve replacement (TAVR) remains unclear.

Methods

We retrospectively evaluated 467 consecutive patients who underwent transfemoral TAVR from January 2016 to April 2021. Cox proportional hazards regression was performed to identify risk factors for all-cause mortality. The primary endpoint was the all-cause mortality, and the secondary endpoints were the occurrence of the aortic dissection and/or rupture.

Results

One hundred patients (21.4%) presented preoperative AA ≥45 mm. The median age was 73 years for patie
