Stentless biological aortic prostheses are used routinely in aortic valve replacement surgery, offering beneficial hemodynamics compared to stented biological valves of similar size. We report here a rare case of early stenotic prosthesis failure of a RootElan stentless porcine aortic valve prosthesis due to swelling at the bottom of the right coronary cusp of the prosthesis.
无支架生物主动脉瓣膜假体在主动脉瓣置换手术中常规使用，与类似尺寸的有支架生物瓣膜相比，具有有利的血流动力学。我们在此报告一例罕见病例，即RootElan无支架猪主动脉瓣膜假体早期出现狭窄性假体功能障碍，原因是假体右冠状动脉瓣叶底部肿胀。
