Tetralogy of Fallot and coarctation of the aorta: successful repair in an infant.

A 4 1/2-month-old infant was referred to our center with the rare combination of tetralogy of Fallot and coarctation of the aorta. Despite the presence of severe right ventricular outflow obstruction, the infant was virtually acyanotic because of the systemic afterload associated with the coarctation. She had marked systemic hypertension. The embryological and therapeutic implications of this child's defects are discussed.
