Tetralogy of Fallot [S,D,I]: successful repair without a conduit.

Tetralogy of Fallot [S,D,I] is a recently discovered form of tetralogy with solitus atria (S) and D-loop ventricles (D), but with inverted normally related great arteries (I). Because of infundibuloarterial inversion, the right coronary artery must traverse the stenotic pulmonary outflow tract, increasing the risk of surgical trauma to the right coronary artery. Here we report a case of successful surgical repair of tetralogy of Fallot [S,D,I] without the use of an extracardiac conduit.
