Results of an autologous tissue reconstruction for replacement of obstructed extracardiac conduits

Between May 1983 and March 1, 1995, 50 patients had replacement of an obstructed pulmonary ventricle-pulmonary artery conduit with an autologous tissue reconstruction in which a prosthetic roof was placed over the fibrous tissue bed of the explanted conduit. The roof was constructed with xenograft pericardium (most recently) (n = 42), homograft dura mater (n = 5), or Dacron fabric (n = 3). Patient ages ranged from 5 to 34 years (median 16...
