背景--左心室射血分数保留的反常低流量、低梯度主动脉瓣狭窄(LFLG-AS)的临床相关性和处理仍有争议。方法和结果：2000-2010年间，768名左心室射血分数(>；50%)和严重的AS(瓣膜面积)患者接受了研究
Background-The clinical relevance and management of paradoxical low-flow, low-gradient aortic stenosis (LFLG-AS) with preserved left ventricular ejection fraction remain debated. The aim of this study is to determine the features and outcome of LFLG-AS assessed using cardiac catheterization.Methods and Results-Between 2000 and 2010, 768 patients with preserved left ventricular ejection fraction (>50%) and severe AS (valve area
