Fenestrated arterial switch operation: surgical approach to an unusual transposition of the great arteries complex.

Transposition of the great arteries with intact ventricular septum and aortopulmonary window is an extremely rare anatomic combination, having been reported just twice previously. Other authors performed a physiologic repair, because the combination was considered unsuitable for an anatomic repair. We describe the case of a 26-day-old baby with such anatomy who was successfully treated with an arterial switch operation. A 4 mm fenestration at atrial level was made for a smoother postoperative course.
