Mechanical valve failure is a known but rare occurrence in cardiac surgery. A 71-year-old lady underwent surgery for failure of her mechanical aortic valve. It was replaced with another mechanical valve. However, during operative manipulation, both leaflets fractured, resulting in a prolonged operative time. Under these circumstances, a novel approach was adopted and a bioprosthetic valve was implanted on the mechanical valve sewing ring as a final resort. The intervention was successful. This illustrates a case of the need for innovative approaches in cardiac surgery.
机械瓣膜故障在心脏手术中是已知但罕见的情况。一位71岁的女士因机械主动脉瓣故障接受了手术。该瓣膜被另一个机械瓣膜替换。然而，在手术操作过程中，两个瓣叶都发生了断裂，导致手术时间延长。在这种情况下，采用了一种新方法，作为最后手段在机械瓣膜缝合环上植入了一个生物人工瓣膜。干预成功。这说明了心脏手术中需要创新方法的一个案例。
