Sarcopenia index as a predictor of clinical outcomes in older patients undergoing transcatheter aortic valve replacement.

Background: Sarcopenia is a prevalent condition in elderly patients and has been associated with adverse outcomes following transcatheter aortic valve replacement (TAVR). The present study aimed to determine the predictive value of serum creatinine-cystatin C ratio, that is, "Sarcopenia Index" (SI) as a surrogate marker of sarcopenia, and investigate its association with clinical outcomes after TAVR.

Methods: We conducted a retrospective observational study of patients undergoing TAVR between January, 2016 and December, 2018 at Hospital Italiano de Buenos Aires, Argentina.
