A six-year-old child was suffering from pulmonary atresia with ventricular septal defect after a total correction at 1 year of age using a bovine pericardial monocusp valve in the reconstruction of the right ventricle outflow tract. The infant evolved with significant pulmonary valve regurgitation (PVR) and right ventricle dysfunction. On reoperation, a cryopreserved pulmonary homograft (CPH) was implanted with annuloplasty utilizing a Delrin ring with the aim of avoiding geometric distortion of the vessel. After two years, an echocardiogram proved a similar state to the immediate postoperative period with slight pulmonary valve regurgitation and normal right ventricular function suggesting that this maneuver may be used as coadjuvant treatment to optimize the result of CPH implantation.
