Anomalous origin of the left coronary artery from the pulmonary artery with proximal hypoplasia of the anomalous coronary artery: diagnostic value of the intercoronary collateral flow detected by color Doppler flow mapping

We describe a case of a child with anomalous origin of the left coronary artery from the pulmonary artery and proximal hypoplasia of the anomalous coronary artery, in whom the diagnosis was suggested only by the intercoronary collateral flow, detected by color Doppler flow mapping.
