Abstract
Failure of a bioprosthetic valve within a composite graft presents a challenging surgical problem. A solution to this, as described here, involves leaving a remnant of the failed valve intact within the graft. This forms the annulus to which the new valve is sewn, thus simplifying the operation.
摘要
复合移植物内生物假体瓣膜的失效是一个具有挑战性的外科问题。此处所述的解决方法是在移植物内保留失效瓣膜的残余部分并使其保持完整。这就形成了用于缝合新瓣膜的瓣环，从而简化了手术。
