The LV volume and ejection fraction (EF) were measured with the modified biplane Simpson's method from the apical 4- and 2-chamber views (20). LV mass was calculated according to Devereux formula (21). Left atrial volume was calculated with the biplane area-length method from the apical 4...
normal ejection fraction (EF) was defined as follows: EF of > 50% and (a) E/e’ ratio > 15, or (b) E/e’ ratio of 8–15 and left atrial volume index ≥ 34 mL/m2. Subclinical hypothyroidism was significantly associated with cardiac indices regarding LV diastolic dysfunct...
The radionuclide method was validated in 34 men (14 normals, 20 with coronary artery disease) with biplane right ventriculography (r = 0.82). Using this radionuclide method right ventricular ejection fraction was measured in 26 men (average age 51 years) with an acute transmural myocardial ...

Low-flow, low-gradient (LF-LG) aortic stenosis (AS) may occur with depressed or preserved left ventricular ejection fraction (LVEF), and both situations are among the most challenging encountered in patients with valvular heart disease. In both cases, the decrease in gradient relative to AS ...

In addition to left ventricular ejection fraction (LVEF), Maceira et al. have provided additional functional parameters that may be useful in some settings [10]. These are summarized in Table6. For diastolic function, the derivative of the time/volume filling curve expresses the peak filling rat...
Echocardiographic examination at rest was recorded in order to obtain left ventricular (LV) quantitative analysis. LV end-diastolic and end-systolic volumes were measured by 2-D biplane method (modified Simpson’s rule) and LV ejection fraction (%) derived [...
(LV) quantitative analysis. LV end-diastolic and end-systolic volumes were measured by 2-D biplane method (modified Simpson’s rule) and LV ejection fraction (%) derived [13]. LV mass was calculated according to the recommended ASE formula and indexed for body surface area (g/m2) [13]....
Maximal (Volmax) and minimal (Volmin) left atrial volumes were measured using the biplane method of discs and by three-dimensional echocardiographic reconstruction using the cubic spline interpolation algorithm. The passive filling, conduit, and active emptying volumes were also estimated. Traditional ...
