Late results of double-valve replacement with biologic or mechanical prostheses.
The Annals of Thoracic Surgery(2001)
摘要
Background. We previously showed that the risk of reoperation for structural degeneration of bioprostheses was higher in cases involving patients older than 65 years (p = 0.003) and double-valve replacement (p = 0.02). The purpose of this study was to compare late outcome of mitral-aortic valve replacement using bioprostheses or mechanical valves.
