Popis: OBJECTIVES To assess the impact of low flow with and without preserved left ventricular ejection fraction (LVEF) on outcomes after transcatheter aortic valve replacement (TAVR). BACKGROUND Prior studies have shown that patients with low flow, AVG, and LVEF have worse outcomes after TAVR. It is unclear whether low AVG and LVEF remain prognostic after adjusting for flow, and how the outcomes of patients with low flow with and without preserved LVEF compare after TAVR. The goal of this study was to provide insight into these open questions. METHODS Data from 340 TAVR patients at Brigham and Women's Hospital from 2011 through 2015 were analyzed. Low flow was defined as stroke volume index (SVI) ≤35 mL/m2 , low AVG as mean gradient
