title: Successful surgical repair of solitus, dextrocardia, atrioventricular discordance, and double outlet right ventricle with l-malposition of the aorta.
abstract: The authors report a rare case of situs solitus of viscera and atria, dextrocardia, atrioventricular discordance, atrial and ventricular septal defects, origin of both great arteries from the morphologic right ventricle, pulmonary valvar and subvalvar stenosis and l-malposition of the aorta which has been correctly diagnosed and succesfully operated on. The repair was accomplished by closing the ventricular septal defect through a ventriculotomy in the systemic venous ventricle (morphologic left), and placing a conduit between this ventricle and the pulmonary artery which had been ligated proximally. The conduit was a fresh segment of homograft valved ascending aorta fixed on a Dacron woven tube. The authors discuss: firstly the reasons for performing this type of repair instead of the intraventricular one recommended by the Mayo Clinic group in the past and secondly the peculiar location of the conducting tissue and the method of avoiding it when approaching the ventricular septal defect.
