[Pre- and postoperative study of neonatal transposition of the great vessels by magnetic resonance imaging].

The authors report the case of a 34 weeks premature infant presenting a transpositions of the large vessels, who underwent a Rashkind during the neonatal period, a Senning procedure at three months, and was explored and followed-up by magnetic resonance imaging (MRI). The images obtained are of good quality, permitting a precise diagnosis of transposition of the large vessels and visualization of an inter-ventricular communication (IVC) which were missed on ultrasonography. The MRI shows complete images of the Senning correction and permits a non-invasive post-operative monitoring of this correction. MIR is therefore an interesting second intention examination which may effectively complement ultrasonography and limit the indications of angiography.
