[Prenatal three-vessel and tracheal view: normal features].

Congenital heart disease (CG) are mostly from a low-risk population. Their screening should be based on reproducible and easy to use methods. Prenatal echocardiographic analysis is based primarily on the analysis of the four chambers and great vessels. The study of general admission pathways generalized since the 1980s is performed on an axial section while that of great vessels is performed in most countries more recently using several views and remains difficult. We review the features, under normal circumstances, of the three-vessel and tracheal view that allows via an axial section of the fetal thorax to assess at the same time the trunk of the main pulmonary artery and its branches, the convergence of the ductus arteriosus and the aortic arches, the superior vena cava, and the trachea. Furthermore, the use of color Doppler mode optimizes the information obtained by this view.
