Abstract

Crossed pulmonary arteries are rare anomalies of the pulmonary trunk and its branches. In this anomaly, the ostium of the left pulmonary artery originates superiorly and to the right of the right pulmonary artery. This anomaly is usually associated with other congenital cardiac and extracardiac diseases. We report three neonates with congenital cardiac diseases who had this anomaly, which was detected first by echocardiography and then confirmed by cardiac three-dimensional computed tomography.

Movie 1 High left parasternal short-axis echocardiographic video. By giving anterior angulation to the probe, the left pulmonary artery is shown to be lying superiorly from right to the left and by posterior angulation and the right pulmonary artery is shown to be lying inferiorly from left to the right (crossing each other) (WMV 857 kb)

Movie 2 Color Doppler echocardiograpic video of crossed pulmonary arteries from high left parasternal short axis. Color Doppler also shows turbulent flow, which diagnoses valvulary pulmonary stenosis (WMV 1872 kb)

Movie 3 A 3D multislice computed tomographic video of crossed pulmonary arteries. The left pulmonary artery coursing superiorly from right to the left and right pulmonary artery lying inferiorly from left to the right (WMV 474 kb)
