Results: Fifty-two newborns presented in acute settings with aortic coarctation and were included in the study, divided into: subgroup 1 (n = 26) - ductal-dependent aortic coarctation; subgroup 2 (n = 2) - non-ductaldependent aortic coarctation; and subgroup 3 (n = 24) - unconfirmed aortic coarctation.

Conclusions: The CSAi and I/D indices are simple and accessible echocardiographic parameters that can provide supplemental information for the pediatric cardiologist in acute cases of newborns with suspicion of aortic coarctation.
