May aid neonatal echo interpretation with updated weight-based norms differing from prior reports; leaves open prospective validation.
What are the normal values for cardiac and great arterial dimensions in premature and full-term infants measured by cross-sectional echocardiography?
This study establishes normal reference values for cardiac and great arterial dimensions in premature and full-term infants, demonstrating a linear correlation with body weight.
Imai et al. (1995) studied this question.
