Evaluation of lv systolic function l.jpg
Evaluation of LV Systolic Function

ESD = LVIDs

EDD = LVIDd

FS= LVIDd - LVIDs

LVIDd


Evaluation of lv systolic function34 l.jpg
Evaluation of LV Systolic Function

EF = LVIDd3 – LVIDs3

LVIDd3









Evaluation of lv mass l.jpg
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 mass43 l.jpg
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

RA and LA Area


Simpson s rule l.jpg
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.
