[Aortopulmonary fistula with interventricular defect and pulmonary valve stenosis in a 15-year-old girl. Surgical correction].

A young girl of 15 with an aorto-pulmonary fistula was treated surgically, with a successful outcome. The clinical diagnosis could only be established at right-sided catheterisation, and especially at retrograde per-arterial aortography. The small size of the fistula explains the low level of the pulmonary arterial hypertension, and the way in which the condition was well-tolerated for some time. The association of this lesion with ventricular septal defect and pulmonary stenosis is extremely rare.
