Valved and nonvalved right ventricular-pulmonary arterial extracardiac conduits

Long-term follow-up of patients with extracardiac valved conduits.

Seventeen patients having extracardiac valved conduits placed between the right ventricle and pulmonary artery were followed for 7 to 87 months postoperatively (mean, 42 months), at the Heart Institute, Kenritsu Amagasaki Hospital, Japan. There were no late deaths in the study group. Three conduits have been replaced, all because of conduit stenosis. In two-dimensional echocardiographic examina...

Composite valved apico-aortic conduits for left ventricular outflow obstruction.

Problems related to the left ventricular outflow tract are not always amenable to conven— tional surgical metiuxis. and in some cases may be solved with the creation of a double ouclet left ventricle, using a composite rigid pyrolitc lcÍt ventricular apex outlet prosthcsis and a fabric valve-containing conduit. The prilnary indicacion for apico—aortic conduirs is severe left ventricular outlet ...

Late results of right ventricular outflow tract reconstruction with Björk-Shiley valved conduits.

Between 1971 and December 1976, 27 children with congenital heart disease underwent right ventricular outflow tract reconstruction with conduits incorporating a Björk-Shiley valve. The conditions corrected were pulmonary atresia with ventricular septal defect (14 patients), truncus arteriosus (6 patients), and complex disease (7 patients). At operation the children were aged from 12 days to 16 ...
