We report the observation of a female patient with a corrected transposition of the great arteries, ventricular septal defect and complete atrio-ventricular block. This complex cardiac disease originated heart failure and was discovered at the age of 4 months. This baby has been operated at the age of 7 months, in April 1998. She had a complete repair by the double switch, closure of the ventricular septal defect and implantation of a permanent pace-maker. Short term results are favorable. Total repair of the corrected transposition of the great arteries is currently possible thanks to the recent technique of the double switch. It remains a difficult operation but with satisfactory short term results.
