Insertion of an aortic and pulmonary homograft for simultaneous reconstruction of the left and right ventricular outflow tracts. A case report.
We present the case of the successful reconstruction in a child of a congenital cardiac malformation (tetralogy of Fallot) complicated by acquired aortic regurgitation and aneurysm formation of the left pulmonary artery due to previous endocarditis, by using an aortic homograft for reconstruction of the left ventricular outflow tract and a pulmonary homograft for reconstruction of the right ventricular outflow tract. Regarding the excellent results recently obtained with cryopreserved homografts, the many advantages of these valves compared to mechanical prostheses, we feel that aortic and or pulmonary homografts might constitute ideal biological valves for reconstruction of left and or right ventricular outflow tract in children when the presence of a congenital anomaly of the pulmonary valve renders an autograft impossible.
