Table 2 Echocardiographic data derived by conventional 2D measurements.

From: Quantitative analysis of left atrial function in asymptomatic patients with b-thalassemia major using real-time three-dimensional echocardiography

End-diastolic diameter of the LV (mm) 44.8 ± 3.4 46.1 ± 2.6 0.1
End-systolic diameter of the LV(mm) 29.4 ± 1.5 28,9 ± 1,2 0.4
Ejection Fraction (%) 59 ± 2.5 60.0 ± 2.1 0.1
Intraventricular septum diameter (mm) 8.2 ± 0.8 8.2 ± 0.9 0.9

  1. Values are expressed as mean and standard deviation. LA = left atrial; LV = left ventricle; RV = right ventricle. In all cases differences were not statistically significant (p = NS).
