Evaluation of LV Systolic Function ESD = LVIDs EDD = LVIDd FS= LVIDd - LVIDs LVIDd
Evaluation of LV Systolic Function EF = LVIDd3 – LVIDs3 LVIDd3
Evaluation of LV Mass This is done by tracing the epicardial to calculate the total ventricular volume and the endocardial border to calculate chamber volume. LV mass = 1.05 (total volume – chamber volume)
Evaluation of LV Mass Total volume= Total area x length Chamber volume = Chamber area x Length Myocardial volume = Total volume – Chamber volume LV mass = Myocardial volume x density LV mass = Myocardial volume x 1.05
Apical-4 Chamber LV Length
Apical – 4 Chamber RA and LA Area
Simpson’s Rule For this method, endocardial borders are traced in apical four-chamber and two-chamber views and are used to define a series of orthogonal diameters (a and b) as follows: V = (p ) S ai bi x (L) 4 20 Using 20 disk for i = 1 to i = 20 This calculation is done by computer software.
