Psoas Muscle Area as a Predictor of Outcomes in Trans-Catheter Aortic Valve Implantation

Frailty is a powerful predictor of outcomes after transcatheter aortic valve implantation (TAVI). Sarcopenia as assessed by psoas muscle area (PMA) is a validated tool to assess frailty prior to surgical procedures. We evaluated PMA as a predictor of outcomes after TAVI in 152 consecutive patients who underwent this procedure at our institution between 2011 2014. Preoperative computed tomography scans were used to measure PMA, which then was indexed to body surface area. Outcomes evaluated included: 1) early poor outcome (30 day mortality, stroke, dialysis, and prolonged ventilation), 2) one year mortality and 3) high resource utilization (length of stay>7 days, discharge to rehabilitation, or readmission within 30 days).
