Prognostic Implications of Psoas Muscle Area in Patients Undergoing Transcatheter Aortic Valve Implantation

Kofler and colleagues evaluated prospectively-measured psoas muscle area in more than 1,000 patients who underwent transcatheter aortic valve replacement at two centers. Indexed psoas area was independently associated with 30-day and follow-up mortality. The authors suggest adding indexed psoas area to The Society of Thoracic Surgeons (STS) score to improve the STS score prognostic value.
