Single-stage correction, with extensive pulmonary arterial reconstruction, of a pulmonary arterial sling associated with tetralogy of Fallot.

Pulmonary arterial sling, rare in itself, is even rarer when associated with tetralogy of Fallot. Successful single-stage correction of this combination, with extensive pulmonary arterial reconstruction, has been reported only occasionally. We describe our experience with an 18 month-old girl, showing that extensive reconstruction of both the pulmonary arteries and the right ventricular outflow tract can permit single-stage correction in selected patients, resulting in favourable physiology and anatomy.
