Takagi H, et al. - In patients undergoing transcatheter aortic valve implantation (TAVI), researchers investigated the predictive value of psoas-muscle area (PMA) on mortality. For this purpose, they analyzed currently available data from studies reporting ≥ 1-year all-cause mortality in PMA-stratified TAVI patients. They used the random-effects model to combine study-specific estimates. They carried out a primary meta-analysis and a subgroup meta-analysis. Findings revealed that high all-cause mortality at midterm follow-up after TAVI was predicted by low PMA, especially “lowest-tertile/quartile” PMA, for both men and women. However, PMA categorization into 50th percentiles may be invalid to predict mortality.
