摘　　要：目的探讨人工机械瓣功能障碍早期诊断及治疗，提高对人工机械瓣膜置换术后机械瓣膜功能障碍的认识。方法回顾性分析27例手术治疗人工机械主动脉瓣、二尖瓣功能障碍患者的临床资料，并复习相关文献资料。结果27例患者确诊为人工机械瓣膜功能障碍，其中二尖瓣置换术后11例、主动脉瓣置换术后12例、双瓣置换术后4例。通过急诊或限期行人工瓣膜再次置换手术治疗，死亡2例（7.4％），其余恢复良好，术后心功能状况改善明显。结论对于人工机械瓣置换术后的患者远期出现类似于瓣膜狭窄的病理生理改变及相关的临床症状时，应高度怀疑人工机械瓣膜功能障碍可能，其合并出现急性功能障碍时常表现危重，应争取时间尽快再手术，这是挽救患者生命的重要手段。Objective To investigate the early diagnosis and treatment of mechanical prosthetic valve dysfunction and to improve the understanding of mechanical valve dysfunction after prosthetic valve replacement. Methods The clinical data of 27 patients with aortic valve or mitral valve dysfunction were reviewed and summarized, and the relevant literature was reviewed. Results 27 patients were diagnosed with prosthetic mechanical valve dysfunction, among them, 11 cases underwent mitral valve replacement, postoperative aortic valve replacement in 12 patients, after mitral valve combined aortic valve replacement in 4 patients. Surgical treatment of emergency prosthetic valve replacement with emergency or limited time, 2 cases of patients died, the mortality rate was 7.4%. The rest recovered well, and the postoperative cardiac function improved obviously. Conclusion For patients with prosthetic valve replacement with long-term pathophysiological changes similar to valvular stenosis and related clinical symptoms, should be highly suspected highly suspected prosthetic valve dysfunction. When combined with acute dysfunction, it often shows serious illness, and should be reoperated as soon as possible, which is an important means to save the patient＇s life.
