The Utility of Psoas Muscle Assessment in Predicting Frailty in Patients Undergoing Transcatheter Aortic Valve Replacement

<div>Cross-sectional psoas and vertebral body areas derived from an axial CT image at the level of L4, using a freehand region-of-interest tool (green outlines). In this patient, the PLVI was mean psoas area (mm<sup>2</sup>)/vertebral body area (mm<sup>2</sup>) ((695 + 708)/2)/1110 = 0.63.</div>
