Surgical experience with anatomically corrected malposition of the great arteries without subpulmonary conus.

ABSTRACT

A three-year-old boy was operated on with the diagnosis of anatomically corrected malposition of the great arteries (S,D,L), ventricular septal defect, and mitral regurgitation. During the operation, it was found that the subpulmonary conus was absent. Ventricular septal defect was patch-closed, and the mitral valve was repaired. The patient was well after the surgery. This is the first case report to our knowledge of the successful surgical repair in anatomically corrected malposition of the great arteries without subpulmonary conus. Anatomically corrected malposition of the great arteries does not always have bilateral conus as once proposed, and the importance of the differentiation from the corrected transposition of the great arteries is emphasized.
