The Medtronic freestyle aortic root bioprosthesis (Medtronic, Inc., Minneapolis, MN, USA) is a stentless valve with an effective orifice area that is larger than that observed on other bioprostheses. However, there have been sporadic reports of structural valve deterioration (SVD), such as aortic root wall rupture, leaflet tearing, and pseudoaneurysm formation. We report five cases of SVD of freestyle aortic root bioprostheses.
美敦力自由式主动脉根部生物假体（美敦力公司，美国明尼阿波利斯）是一种无支架瓣膜，其有效瓣口面积大于其他生物假体。然而，已有零星报道称出现了结构性瓣膜退变（SVD），如主动脉根壁破裂、瓣叶撕裂和假性动脉瘤形成。我们报告了5例自由式主动脉根部生物假体的SVD病例。
