Sutureless aortic bioprostheses (SAB) provide shorter aortic cross-clamp time and cardiopulmonary bypass duration compared to conventional aortic valve replacement. Similarly to other bioprostheses, reintervention may become necessary in some cases because of long-term structural degeneration of the valve. Valve-in-valve (ViV) transcatheter aortic valve replacement may represent an effective and safe alternative to aortic valve replacement in patients with degenerated bioprostheses who carry a high risk for reintervention. We report the case of a self-expandable transcatheter ViV procedure in a degenerated SAB.
与传统主动脉瓣置换相比，无缝合主动脉生物假体（SAB）可缩短主动脉阻断时间和体外循环持续时间。与其他生物假体类似，由于瓣膜的长期结构退变，某些情况下可能需要再次干预。对于再次干预风险较高的生物假体退变患者，瓣中瓣（ViV）经导管主动脉瓣置换术可能是主动脉瓣置换的一种有效且安全的替代方法。我们报告了1例在退变的SAB中进行的自膨胀式经导管ViV手术病例。
