Real time 2D-Doppler, ALCAPA
A real-time two-dimensional Doppler flow imaging and a pulsed Doppler were used for blood flow analysis in a 6 months old infant with anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA). Following findings were obtained. 1) Turbulent flow patterns were seen in the pulmonary trunk near the left coronary artery orifice. 2) Blood flow from the left coronary artery to the pulmonary trunk was observed on two-dimensional Doppler imaging. In conclusion, a real-time two-dimensional Doppler flow imaging is useful method for the diagnosis of ALCAPA and the judgement on the direction of the coronary artery flow.
