Anatomic correction of dextrotransposition of the great arteries in a 36-year-old patient

During the 1960s, the Mustard or Senning operation was the conventional palliative therapy for patients with transposition of the great arteries. Many of these patients are now adults, and the durability of the morphologic right ventricle to function as the systemic ventricle is being questioned. Surgical options for such adult patients have traditionally been limited to cardiac transplantation. More recently, an arterial switch operation with take-down of the Mustard or Senning baffles has been reported. Herein we describe the clinical course of a 36-year-old woman who underwent a successful single-stage Mustard take-down, atrial reconstruction, and arterial switch operation.
