Usefulness of the Mitral Regurgitation Severity Index to Assess the Severity of Chronic Mitral Regurgitation

Abstract Existing metrics for grading mitral regurgitation (MR) are limited in terms of high inter-observer variability. We developed and evaluated a Doppler-based, semi-quantitative novel index (Mitral Regurgitation Severity Index, MRSI) of MR severity. In a total of 125 patients (70 in the derivat...
