Mitral and Aortic valve rings were enlarged in a 70-year-old female with tiny mitral annulus after mitral annuloplasty before. She had undergone aortic valve replacement with No. 21 SJM valve and Kay's annuloplasty 10 years previously. The reoperation was needed because of mitral stenosis and tricuspid regurgitation. We applied the Manouguian technique for the enlargement of the mitral annulus because it was too small to implant a prosthetic valve, even though the Aortic prosthetic valve was functioning well. As too tight a mitral annuloplasty may make the possibility of mitral stenosis real, we should make the annulus remain wide enough.
一名70岁女性，之前二尖瓣环成形术后二尖瓣环仍小，二尖瓣和主动脉瓣环均增大。她10年前接受了21号圣犹达医疗公司（SJM）瓣膜的主动脉瓣置换术及凯氏瓣环成形术。因二尖瓣狭窄和三尖瓣反流需要再次手术。由于二尖瓣环过小，即使主动脉人工瓣膜功能良好也无法植入人工瓣膜，所以我们采用马努吉安技术扩大二尖瓣环。由于二尖瓣环成形术过紧可能导致二尖瓣狭窄成为现实，我们应使瓣环保持足够宽。
