Quantification of aortic valve calcification on contrast-enhanced CT was evaluated in 217 patients with severe aortic valve stenosis prior to TAVI.

Can a formula be developed to accurately quantify aortic valve calcification on contrast-enhanced CT in patients prior to TAVI?
The study aims to develop a formula for quantifying aortic valve calcification directly from contrast-enhanced CT, potentially streamlining pre-TAVI imaging protocols.
AIMS: The aim of the study was to develop a formula enabling the quantification of aortic valve calcification (AVC) on contrast-enhanced CT of patients undergoing transcatheter aortic valve implantation (TAVI). METHODS AND RESULTS: Two hundred and seventeen (217) consecutive patients with severe aortic valve stenosis undergoing non-enhanced electrocardiography-gated CT angiography (NECT) and contrast-enhanced electrocardiography-gated CT angiography (CECT) prior to TAVI were subdivided into a training cohort (n=145) and a validation cohort (n=72). Aortic valve calcification (AVC) was semi-automatically segmented on CECT (AVC.
Eberhard et al. (Sun,) conducted a cohort in Severe aortic valve stenosis (n=217). Contrast-enhanced CT vs. Non-enhanced CT was evaluated on Quantification of aortic valve calcification. Quantification of aortic valve calcification on contrast-enhanced CT was evaluated in 217 patients with severe aortic valve stenosis prior to TAVI.
