Abstract

A 5 year old boy presented with obstruction of the pulmonary venous pathway four years after the Mustard procedure. A successful balloon dilatation of the pulmonary venous pathway was performed but the benefit was transient. Placement of a 10 mm balloon expandable intravascular stent across the recurrent stenosis resulted in complete relief of the obstruction with prompt resolution of the clinical signs. The delivery system was modified to facilitate stent delivery.
