BACKGROUND
Mechanical aortic valve dysfunction is a rare but potentially fatal complication. It is usually caused by thrombosis, vegetation, and pannus overgrowth. However, it very rarely occurs immediately after the cardiopulmonary bypass weaning period.
CASE PRESENTATION
We describe a case of stuck leaflet after the implantation of a mechanical aortic valve because of residual suture materials interfering with mechanical aortic valve leaflet closure, which is a very rare cause and has not been reported until now.
CONCLUSION
The residual suture materials for mechanical aortic valve replacement could cause mechanical valve dysfuction indicated as stuck leafet.
背景
机械主动脉瓣功能障碍是一种罕见但可能致命的并发症。它通常由血栓形成、赘生物和血管翳过度生长引起。然而，它在体外循环脱机后极少见立即发生的情况。
病例报告
我们描述了一例机械主动脉瓣植入后瓣叶卡滞的病例，原因是残留缝线材料干扰了机械主动脉瓣叶的关闭，这是一种非常罕见的原因，迄今为止尚未见报道。
结论
机械主动脉瓣置换术中的残留缝线材料可导致以瓣叶卡滞为表现的机械瓣膜功能障碍。
