Computed tomography-based coronary lumen volume to myocardial mass ratio in patients undergoing transcatheter aortic valve replacement: a novel method for risk assessment.

ABSTRACT:

Background

The coronary lumen volume to myocardial mass (V/M) ratio has been suggested as a quantitative metric of potential imbalance between coronary blood supply and myocardial oxygen demand. This study was designed to assess the prognostic value of the V/M ratio for predicting major adverse cardiovascular events (MACE) in patients undergoing transcatheter aortic valve replacement (TAVR).

Methods

This study enrolled patients who received a standard planning computed tomography (CT) scan before TAVR and dichotomized at the median of 33.31 mm³/g of V/M ratio into groups with low V/M ratio and high V/M ratio. The V/M ratio was calculated by coronary computed tomography angiography (CTA). The endpoint was a composite of all-cause mortality, stroke, and hospitalization for hea
