Doppler evaluation of homograft valved conduits in children.
To assess the flow characteristics of homograft valved conduits in the immediate postoperative period, 69 children with 71 homograft conduits underwent 2-dimensional and Doppler echocardiographic examination at 1 to 40 days (mean 8) after surgery. Of the 71 conduits studied, 19 were aortic and 52 were pulmonary homograft valved conduits. Two aortic homograft valved conduits were inserted in the...
متن کاملReconstruction of right ventricular outflow with a valved homograft conduit.
Wheadey, D. J., Prusty, S., and Ross, D. N. (1974). Thorax, 29, 617-623. Reconstruction of right ventricular outflow with a valved homograft conduit. Since 1966 a conduit of homograft ascending aorta with its valve has been used for reconstruction of the right ventricular outflow. This technique has been applied to 123 operations for pulmonary autograft replacement of the aortic valve, 48 opera...
متن کاملOversizing pulmonary homograft conduits does not significantly decrease allograft failure in children.
OBJECTIVE Placement of oversized pulmonary ventricle-pulmonary artery conduits is routinely performed to decrease conduit failure in children. However, this practice has recently been challenged as somatic outgrowth may not be the main determinant of allograft failure in children. Our objective was to determine whether placement of oversized homografts for extracardiac pulmonary ventricle (PV) ...
متن کاملComposite 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 ...
متن کاملLong-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...
