WebAug 12, 2010 · The modified biplane measurements were calculated as the mean of EDVI, ESVI, and ejection fraction (EF) measured in the right parasternal long-axis view, and the left apical 4-chamber view. First, this older control population was used to calculate optimal cut-off values for EDVI (>95 mL/m 2 ) and ESVI (>55 mL/m 2 ) to detect … WebThe average volume estimated echocardiographically by the Simpson's method was 657.5 ± 276.9 mL (range, 205.7-1193.2 mL). There was strong direct linear correlation between echocardiographic and pericardiocentesis-derived volumes (P < 0.001, r = +0.823).
