[Contribution of magnetic resonance imaging in the neonatal diagnosis of congenital cardiopathies. Apropos of 10 cases].

The aim of this study was to evaluate potential indications of Magnetic Resonance Imaging (MRI) in the diagnostic workup of congenital heart disease in the newborn in comparison with two other means of investigation: Doppler-echocardiography and angiography. The imaging permitted to make the diagnosis in the 10 cases. MRI was superior than echocardiography in one newborn with a double aortic arch. MRI detected small muscular ventricular septum defects in two newborns with transposition of the great vessels. There was good agreement between MRI and angiographic images. Neither age nor prematurity proved to pose a limit on the diagnosis of MRI. MRI proved to be a good investigative tool which should be used after echocardiography, eventually making it possible to avoid angiography.
