[Future Aspects of Bio-Bentall Procedure].

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.
