We describe an unusual sequela of mitral valve replacement in a 50-year-old woman who had undergone a closed mitral commissurotomy in 1975. She was admitted to our hospital because of mitral restenosis in November 1993, at which time her mitral valve was replaced with a mechanical prosthesis. On the 8th postoperative day, the patient developed symptoms of heart failure; transesophageal echocardiography revealed dissection and rupture of the left atrial wall. At prompt reoperation, we found an interlayer dissection and rupture of the atrial wall into the left atrium. We repaired the ruptured atrial wall with a prosthetic patch. The postoperative course was uneventful, and postoperative transesophageal echocardiography showed normal prosthetic valve function and no dissection.
我们描述了一名50岁女性二尖瓣置换术后出现的罕见后遗症，该女性于1975年接受了闭式二尖瓣交界切开术。1993年11月，她因二尖瓣再狭窄入住我院，当时其二尖瓣被置换为机械瓣膜。术后第8天，患者出现心力衰竭症状；经食管超声心动图显示左心房壁夹层和破裂。在紧急再次手术中，我们发现心房壁夹层并破入左心房。我们用人工补片修复了破裂的心房壁。术后过程顺利，术后经食管超声心动图显示人工瓣膜功能正常，无夹层。
