LVEDD
Also written as: LVEDD — Left Ventricular End-Diastolic Dimension
Left ventricular end-diastolic dimension. Measurement of left ventricle size at maximum filling, important marker of ventricular remodeling.
Full Definition
Left ventricular end-diastolic dimension (LVEDD) is the internal diameter of the left ventricle measured at end-diastole, typically obtained from parasternal long-axis echocardiographic views or cardiac MRI. Normal LVEDD ranges from 42-59mm in men and 39-53mm in women, with values indexed to body surface area for more accurate assessment. Increased LVEDD indicates ventricular dilation and is associated with volume overload, cardiomyopathy, or chronic valvular disease. Serial LVEDD measurements help monitor disease progression and treatment response in conditions like aortic regurgitation or dilated cardiomyopathy.
Usage
Usage note: Report in centimeters or millimeters consistently; consider indexing to BSA for accurate assessment.
