Abstract

Low cardiac output syndrome (LCOS) after surgical aortic valve replacement (SAVR) is related to increased mortality and treatment related costs. We aimed to evaluate whether echocardiography-derived left ventricular global longitudinal strain (LV-GLS) relates to the occurrence of postoperative LCOS in patients undergoing SAVR. We prospectively enrolled 75 patients with symptomatic severe aortic stenosis, left ventricular ejection fraction (LVEF) >40%, NYHA Class
