Left Ventricular Dimensions
The Left Ventricular
Each echocardiogram is an evaluation of the LV dimensions, wall thicknesses and described function.
Good and measurements are essential and may have implications for therapy. The LV dimensions must be measured as the end-diastolic and end-systolic valves (MV and AoV) are closed. Plax in The measurement is located in the basal portion of the LV by the chordae.
