We compared different conduits for the right ventricular outflow tract reconstruction (RVOT) in adults during the Ross procedure. Between 1998 and 2012, 586 consecutive adult patients underwent the Ross procedures. Mean age was 45,514,2 years. The RVOT was reconstructed with a diepoxy-treated xenografts in 372 and with glutaraldehyde-treated in 88 patients. A pulmonary homograft was used in 125 patients. Hospital mortality was 4,9%. Mean follow up was 43,216,9 months. At discharge systolic gradient was 8,1 3,7 mm.Hg for the pulmonary homograft, 11,44,7 mm.Hg for the diepoxytreated and 14,96,1 mm.Hg for the glutaraldehyde-treated xenopericardial conduits. Twenty eight patients underwent reoperation. The 3-year actuarial freedom from conduit explantation for pulmonary homograft was 100%, for diepoxy- and glutaraldehyde-treated xenopericardial conduits 99,20,7% and 84,74,7% respectively. Multivariable analysis identified the type of xenograft and age as independent factors for xenograft dysfunction. Results from this study show that the pulmonary homograft is the most preferred conduit for the RVOT reconstruction during the Ross procedure. The diepoxy-treated xenopericardial conduits are acceptable alternative to the homograft in patients older 45 years.

Abstract Isolated sub-pulmonary membrane is a rare condition, the origin of which has been debatable. Transcatheter treatment of pulmonary valve atresia with intact interventricular septum by radiofrequency perforation and balloon dilatation to restore biventricular circulation is gaining more popularity, with improving results over time. We report in our experience of 79 cases in 10 years the development of a sub-pulmonary membrane in 4 cases: causing significant obstruction requiring surgical excision in one case that revealed a fibrous membrane on pathology; causing mild right ventricular outflow tract obstruction in another and not yet causing obstruction in 2. On cardiac MRI, the right ventricular outflow tract and the right ventricular outflow tract/pulmonary atresia angle showed no morphological abnormalities.
