Coronary artery abnormalities in children.

Although coronary artery abnormalities are somewhat rare in children, they constitute a population at significant risk for morbidity and/or mortality. The expeditious and accurate diagnosis of these lesions is imperative for optimum management. The ability of two-dimensional and Doppler echocardiography to accurately evaluate coronary artery abnormalities in children will be discussed under three headings: (1) major congenital coronary artery anomalies, (2) coronary artery anomalies associated with specific congenital heart lesions, and (3) acquired coronary artery abnormalities.
