van Mourik MS, et al. - Researchers evaluated if the psoas muscle area (PMA) measurement has any predictive value for mortality in the transcatheter aortic valve implantation (TAVI) population. They reviewed multi-slice computed tomography scans (between 2010 and 2016) of 583 consecutive TAVI patients who were categorized into equal sex-specific tertiles (low, mid, and high) according to an indexed PMA. For cardiac and all-cause mortality following TAVI, the hazard ratios and their confidence intervals were calculated. Findings revealed an independent association of low iPMA with a higher all-cause and cardiac mortality. This was seen especially in females. An improved predictive value for 1-year mortality was seen in females when iPMA was added to surgical risk scores.
