What are the normal echocardiographic diameters and ratios of the pulmonary trunk and aortic root in infants and children?
The ratio of the pulmonary trunk to aortic root is remarkably constant at ~1.06 throughout childhood after the first week of life, providing a useful reference for assessing congenital heart disease.
Ichida et al. (1987) studied this question.
