Cardiac morphology at 2 and 10 years after CDH repair: MRI comparison of ECMO and non-ECMO patients

In children after CDH repair, those requiring ECMO had higher RV/LV ratio and eccentricity index at 2-year MRI, suggesting persistent pulmonary hypertension. These normalized by 10 years. ECMO independently predicted elevated EI (OR 7.68, 95% CI 1.93–30.47).

• Retrospective analysis of MRI data from 57 children after CDH repair (31 ECMO-treated, 26 non-ECMO).
• At 2 years, PA/Ao ratio did not differ significantly between groups; at 10 years, no measured cardiac parameters differed.
• Retrospective design limits causal inference.
