Successful modified Senning operation for the repair of Taussig-Bing malformation

Surgical correction was carried out successfully in a severely cyanotic 3-year-old boy with Taussig-Bing malformation. The cardiac anomaly was associated with semilunar valves side by side, and at the same height, a bilateral conus without pulmonary-mitral continuity and subpulmonary ventricular septal defect, on which pulmonary valve overode. The surgical correction consisted of the closure of the VSD by a right atrial approach and modified Senning procedure under profound hypothermic cardiac arrest with surface cooling and limited cardiopulmonary bypass. The patient survived operation and was doing well 10 months after surgery. To our knowledge, no other identical case with Taussig-Bing malformation has been corrected successfully by this procedure nor has previously been reported.
