Key result
The right ventricle to left ventricle inflow angle was the dominant echocardiographic variable differentiating right dominant unbalanced from balanced AVSD (partial R²=0.86).

What echocardiographic features differentiate right dominant unbalanced atrioventricular septal defect from balanced AVSD?
Effect estimate: partial R²=0.86
The angle of right ventricle to left ventricle inflow is a key echocardiographic measure for defining right dominant unbalanced atrioventricular septal defect.
Cohen et al. (2013) conducted an observational in Atrioventricular septal defect (AVSD) (n=112). Echocardiographic features (right ventricle:LV inflow angle) vs. Balanced AVSD was evaluated on Differentiating echocardiographic variables between cluster groups (partial R²=0.86). The right ventricle to left ventricle inflow angle was the dominant echocardiographic variable differentiating right dominant unbalanced from balanced AVSD (partial R²=0.86).
