LV End-Diastolic Volume Index (LVEDVI): Explanation and Clinical Context LV End-Diastolic Volume Index (LVEDVI) represents the volume of blood in the left ventricle at the end of diastole, normalized to body surface area (BSA). It is a fundamental echocardiographic parameter to assess left ventricular size and remodeling. In clinical practice, LVEDVI helps detect dilated cardiomyopathy, monitor heart failure progression, and guide management in patients with valvular heart disease or after myocardial infarction.
Normal ranges differ by sex: men typically 55–105 mL/m² and women 45–95 mL/m². Values above these thresholds suggest left ventricular dilation, which is associated with adverse cardiovascular outcomes. Accurate measurement of LVEDVI is recommended using 2D or 3D echocardiography with Simpson’s biplane method, as described in guideline-referenced publications.
