Impact of left ventricular outflow tract ellipticity on the grading of aortic stenosis in patients with normal ejection fraction

The pathophysiology of paradoxical low-gradient (LG) severe aortic stenosis (SAS) remains controversial. As low transvalvular flow has been implicated, we sought to investigate the impact of left ventricular o...
