TRANSCATHETER STENT IMPLANTATION FOR RECURRENT PULMONARY VENOUS PATHWAY OBSTRUCTION AFTER THE MUSTARD PROCEDURE

A 5 year old boy presented with obstruction of the pulmonary venous pa thway four years after the Mustard procedure. A successful balloon dil atation of the pulmonary venous pathway was performed but the benefit was transient. Placement of a 10 mm balloon expandable intravascular s tent 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.
