[Spiral CT scan imaging of the coronary vessels six years after complete repair of a Taussig-Bing malformation].

The Taussig-Bing malformation is a rare form of transposition of the great arteries with a ventricular septal defect. Associated cardiac abnormalities are common: hypoplasia of the aorta and especially coronary anomalies which may complicate surgical repair. The authors report the case of a patient with this malformation diagnosed in utero and who underwent anatomical repair on the 11th day of life. The coronary anatomy described by the surgeon was type E of Yacoub and Radley-Smith's classification. The postoperative course was uncomplicated. At the age of 6, a spiral CT scan was performed routinely under betablocker therapy. The coronary trajectory with a double loop, the patency of the coronary ostia and of the aortic isthmus were accurately demonstrated by this form of imaging.
