Validation of left ventricular early inflow-outflow index: A novel echocardiographic method for quantification of mitral regurgitation in an Indian population with special focus on rheumatic etiology

摘要

Quantification of mitral regurgitation (MR) has always required an “integrated approach” as there is no single gold-standard method. We investigated a new Doppler-derived parameter “left ventricular early inflow-outflow index (LVEIO)” for the quantification of MR and its likelihood to predict severe MR in correlation with already established parameters in an Indian population including a large subset of patients with rheumatic etiology.
