Transmitral flow = … Webatrial pressure, and LVEDP is very close to mean left ventricular diastolic pressure (LVDP).t.2 Acute increases of LVEDP by hypervolemia result in a proportionate increase of mean left atrial pressure." However, LVEDP exceeds LV diastolic pressure prior to atrial contraction (LVDP pre "a") by an average of 1.6 mm Hg.2 Thus, in normal subjects,
