Popis: OBJECTIVES The aim of this study was to determine the prognostic value of contractile reserve (CR) at baseline in patients with low-flow, low-gradient severe aortic stenosis (AS) undergoing transcatheter aortic valve replacement (TAVR). BACKGROUND Patients with severe AS, left ventricular dysfunction, and low transaortic gradient are at high risk for mortality during surgical aortic valve replacement (SAVR). Furthermore, patients without CR have been shown to have perioperative mortality comparable to that of patients treated medically for severe AS. METHODS We retrospectively analyzed patients who underwent TAVR with a diagnosis of low-gradient severe AS (mean transvalvular aortic gradient
