Cross-sectional and Doppler echocardiographic diagnosis of anomalous origin of the left coronary artery from the pulmonary artery and right coronary artery from posterior aortic sinus.

A six-year-old asymptomatic child on evaluation for a cardiac murmur, was found on cross-sectional and Doppler echocardiography to have an anomalous origin of the left coronary artery from the pulmonary artery and right coronary artery from posterior sinus of aorta. Doppler studies revealed a continuous signal in the pulmonary artery, indicating a left to right flow. The diagnosis was subsequently confirmed at cardiac catheterization and surgery.
