Purpose/ Objective

With CMR, the left ventricular systolic volume is measured as the volume contained within the LV cavity between the apex and the mitral annular plane. In the presence of a significant mitral valve prolapse, the blood volume contained within the prolapsing leaflets is not measured as a part of the LV systolic volume. A correction of the LV end-systolic volume consisting in adding the blood volume contained between the mitral annular plane and the prolapsing mitral leaflets is proposed, in order to better assess mitral regurgitation severity by a more accurate quantification the mitral regurgitant volume. Following this activity, learners will be better prepared to recognize the usual method of disks is inaccurate for the measurement of the LV endsystolic volume in the presence of a significant mitral valve prolapse, that results in an inaccurate calculation of the LV stroke volume and, as a consequence, in an overestimation of the grade of mitral regurgitation severity, and the use of a simple correction method may improve the accuracy of LV endsystolic volume measurement and mitral regurgitation assessment with CMR.
