BACKGROUND: Successful treatment of destructive @entity886 with annular @entity733 formation requires extensive surgical debridement and reconstruction of the left ventricular outflow tract and aortic root. Homograft aortic roots are the conduits of choice, but because they are not available in all cases, alternative conduits are needed. METHODS: Owing to its features, which are comparable to those of homografts, the Freestyle aortic root xenograft was used in 10 consecutive @entity1 aged between 32 and 77 years. All @entity1 had extensive @entity733 formation, 5 presented with @entity340 , 2 had additional mitral @entity340 requiring partial leaflet resection and reconstruction, 1 @entity1 had an additional @entity292 into the right atrium, and 1 required coronary bypass. One @entity1 developed a septic @entity1757 and @entity292 into the right atrium with @entity1145 . RESULTS: None of the @entity1 required reoperation for @entity548 . Two (20%) @entity1 died in the postoperative period, 1 due to @entity177 , and 1 due to preexisting invasive @entity57 . At autopsy, neither had evidence of intrapericardial @entity1410 or suture dehiscence. One @entity1 died 13 months postoperatively without clinical signs of @entity340 or recurrent @entity884 . All other @entity1 are well at 12 to 42 months after surgery. Clinical examination and echocardiography at the most recent follow-up showed no signs of @entity340 , recurrent fistulation, or @entity884 . CONCLUSIONS: The Freestyle aortic root appears to be an acceptable alternative to homografts in the treatment of severe @entity884 . Long-term valve durability in younger @entity1 , however, remains to be determined.
