van Mourik MS, et al. - Among 583 consecutive transcatheter aortic valve implantation (TAVI) patients, whether the psoas muscle area (PMA) measurement can predict mortality was evaluated by reviewing multi-slice computed tomography scans (between 2010 and 2016) of these patients. Based on an indexed PMA (iPMA), researchers categorized patients into equal sex-specific tertiles (low, mid, and high). To determine cardiac and all-cause mortality post-TAVI, hazard ratios (HR) and their confidence intervals (CI) were estimated. Findings revealed an independent correlation of low iPMA with higher all-cause and cardiac mortality, especially in females. The predictive value for 1-year mortality was improved in females by adding iPMA to surgical risk scores.
