Brovman EY, et al. - In a contemporary cohort of patients undergoing either transcatheter aortic valve replacement (TAVR) or surgical aortic valve replacement (SAVR), patient acuity and perioperative outcomes were examined. Patients undergoing TAVR and those undergoing SAVR were similar in terms of mortality, length of stay, and risk for postoperative complications. However, blood transfusion was less frequently required for patients undergoing TAVR. TAVR was noted in association with age greater than 65 years, patients with dyspnea with moderate exertion or dependence in activities of daily living, high American Society of Anesthesiologists physical status classification, and history of chronic obstructive pulmonary disease. However, SAVR was observed in association with body mass index greater than 25.
