[Fetal cardiac biometry. Evaluation of the growth of the right and left ventricles using bidimensional echocardiography in normal pregnancies].

Two-dimensional echography makes it possible to study the fetal heart in a routine obstetrical setting. It is easy to see the four cavities of the heart from the long axis. The speed of growth of the internal diameters of the right and left ventricles have been studied at different stages of normal pregnancy. In this way it has been possible to show the morphometric equilibrium between the right and the left side at different stages of the pregnancy by cardiac ventricular biometry. These measurement are the first step in screening for intra-uterine cardiac abnormalities.
