Skeletal Muscle Characteristics May Inform Preprocedural Risk Stratification in Transcatheter Aortic Valve Replacement Patients

Low psoas muscle mass previously has been associated with mortality after transcatheter aortic valve replacement (TAVR). Evidence from other clinical disciplines suggests that psoas density (PD) may be a better predictor than psoas muscle cross-sectional area indexed to body surface area (PI). The authors hypothesized that PD would be more strongly correlated with patient discharge disposition and survival after TAVR than PI.The authors...
