Patients and Methods
The institutional review board approved this follow-up study and waived the requirement for patient consent and authorization (CER-08-043R).
Mortality
There was no hospital mortality in the homograft group, whereas 2 patients died of graft-unrelated causes in the Contegra graft group (second and eighth postoperative days). The deaths were attributed to complications of pulmonary hypertension. One patient had as an additional procedure a banding of neo-pulmonary artery that necessitated a debanding on the second postoperative day, after which procedure the patient succumbed. The second mortality was attributable to RV failure on the eighth
Comment
Cryopreserved homografts have been used as a conduit between the RV and the pulmonary arteries for reconstruction of the RVOT since the late 1960s [19]. A pulmonary homograft is the preferred conduit but is often quite difficult to obtain [20]. Aortic homografts have therefore been commonly used in the pulmonary position for RVOT reconstruction. Excellent patient survival after RVOT reconstruction using homografts has been reported [19, 21, 22], which also was demonstrated in the present
