Abstract excerpt
BACKGROUND: In patients undergoing transcatheter aortic valve implantation (TAVI), low flow, low-gradient (LF-LG) often reflects reduced left ventricular ejection fraction (LVEF). However, characteristics and causes of worse outcomes in patients with paradoxical LF-LG and preserved ejection fraction (pEF) remains poorly understood. OBJECTIVES: To phenotype LF-LG pEF patients using unsupervised echocardiographic...
