Impact of left ventricular outflow tract calcification in patients undergoing transfemoral transcatheter aortic valve implantation.

ABSTRACT:

Background

Left ventricular outflow tract (LVOT) calcification is known to be associated with adverse outcomes after transcatheter aortic valve implantation (TAVI) in patients receiving first-generation transcatheter heart valves (THV).

Aims

The aim of the present study was to assess the prevalence of LVOT calcification as well as its impact on outcomes in a contemporary TAVI patient cohort.

Methods

This retrospective single-centre analysis includes 1,207 patients who underwent transfemoral TAVI between 2012 and 2018 and in whom adequate contrast-enhanced multislice computed tomgraphy (MSCT) imaging for quantification of LVOT calcification was available.

Results

Significant LVOT calcification, defined as >10 mm³, was present in 37.4% (n=451) of the p
