The Bentall procedures using biological valved conduit is expanding owing to the increasing incidence of aortic valve disease in the aging population and usage for young generation. The long-term durability of the biological valve including the risks of structural valve deterioration(SVD) is the major concern of the bio-Bentall procedure. Bio-Bentall in our hospital are reviewed and literature review are added. Our surgical results of long-term survival in bio-Bentall patients is acceptable compare to other study and freedom from SVD and reoperation is better than other results. There was no experience of SVD complication so far. Modification using double sewing ring technique is useful to put larger valve, keep better hemostasis, easy to do reoperation for further SVD and expect for future valve in valve situation.
由于老年人群中主动脉瓣疾病发病率的上升以及年轻一代对其的使用，采用生物带瓣管道的Bentall手术正在增加。生物瓣膜的长期耐久性，包括结构性瓣膜退变（SVD）的风险，是生物Bentall手术的主要关注点。我们回顾了我院的生物Bentall手术情况，并增加了文献综述。与其他研究相比，我们生物Bentall患者的长期生存手术结果是可以接受的，并且无SVD和再次手术的情况优于其他结果。到目前为止，尚无SVD并发症的经验。采用双缝环技术进行改良有助于植入更大的瓣膜、保持更好的止血效果、便于因进一步的SVD进行再次手术以及预期未来的瓣中瓣情况。
