Clinical and echocardiographic features of paradoxical low-flow and normal-flow severe aortic stenosis patients with concomitant mitral regurgitation

Mitral regurgitation (MR) coexists in a significant proportion of patients with severe aortic stenosis (AS), and portends inferior therapeutic outcomes. In severe AS, MR is thought to contribute to a low-flow state by decreasing forward stroke volume. We investigated concomitant MR on the clinical a...

Description
Summary:Mitral regurgitation (MR) coexists in a significant proportion of patients with severe aortic stenosis (AS), and portends inferior therapeutic outcomes. In severe AS, MR is thought to contribute to a low-flow state by decreasing forward stroke volume. We investigated concomitant MR on the clinical and echocardiographic features of patients with “paradoxical” low-flow (PLF) and normal-flow (NF) severe AS. Clinical and echocardiographic profiles of 886 consecutive patients with index echocardiographic diagnosis of severe AS (AVA
