Eccentricity Index Is Associated With Pulmonary Arterial Hypertension in Children After Repair of Complete Atrioventricular Septal Defects

After AVSD repair, EIs and EIm are elevated compared to those of otherwise healthy children. However, significant elevation (Eis > 1.28) may still be useful to differentiate those with and without PAH. A multiparametric approach may be needed for borderline EIs (1.09-1.28). These findings support EI as a non-invasive screening tool to identify PAH in children after AVSD repair.
