Several studies analysed computed tomography (CT)-defined sarcopenia in patients undergoing transcatheter aortic valve implantation (TAVI). However, the criteria for CT-defined sarcopenia are heterogeneous among these studies. Mostly, they primarily evaluated short-term outcomes; research focusing on long-term outcomes, related to lifetime management in patients with aortic stenosis, is rare. We assessed the effects of CT-defined sarcopenia on the short- and long-term outcomes in patients undergoing TAVI using three different sarcopenia criteria, including two traditional criteria and a novel criterion.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>METHODS<\/jats:title>\n                  <jats:p>In this retrospective study, we enrolled 360 patients. Three different sarcopenia criteria (skeletal muscle index [SMI], psoas muscle area [PMA] and psoas muscle volume index [PVI]) were applied to assess safety and early and long-term clinical outcomes.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>RESULTS<\/jats:title>\n                  <jats:p>SMI-, PMA- and PVI-sarcopenia were diagnosed in 244 (67.7%), 246 (68.3%) and 161 (44.7%) patients, respectively. However, PMA-sarcopenia was associated with poor long-term survival after TAVI. Furthermore, PVI-sarcopenia was associated with lower safety at 30\u2009days and poor long-term survival. Using Cox regression hazard models, PVI-sarcopenia tended to be a risk factor for overall survival (hazards ratio: 1.49, P\u2009=\u20090.052).<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>CONCLUSIONS<\/jats:title>\n                  <jats:p>In patients undergoing TAVI, CT-defined sarcopenia using PVI-based criteria was a reliable predictor of poor outcomes.
