[Reoperation cases long after Rastelli operation: right ventricular outflow tract reconstruction by means of a...

Two cases who underwent the new procedure of treatment for extracardiac conduit stenosis after Rastelli operation are reported. They had undergone Rastelli operation 11 and 12 years ago. Because of stenotic Hancock valve of the conduit, they were reoperated. A longitudinal incision was made anteriorly over the conduit and the conduit was dissected free. The sides and posterior half of the conduit bed were preserved. The roof of the new right ventricular outflow tract was formed using a xenograft pericardium patch. Their postoperative courses were smooth.
