Incremental prognostic value of intensity-weighted regional calcification scoring using contrast CT imaging in TAVR.

ABSTRACT:

Aims

Aortic valve calcification scoring plays an important role in predicting outcomes of transcatheter aortic valve replacement (TAVR). However, the impact of relative calcific density and its causal effect on peri-procedural complications due to sub-optimal valve expansion remains limited. This study aims to investigate the prognostic power of quantifying regional calcification in the device landing zone in the context of peri-procedural events and post-procedural complications based on pre-operative contrast computed tomography angiography (CCTA) images. Assess the effect of calcification on post-procedural device expansion and final configuration.

Methods and results

We introduce a novel patient invariant topographic scheme for quantifying the location and relative densi
