No data are available in the literature regarding the effectiveness and safety of transcatheter aortic valve implantation in patients who underwent previous mitral valve ring repair. Concerns exist related to the possible interference between the percutaneous aortic valve and the mitral annuloplasty ring. We report our experience with percutaneous aortic self-expandable valve implantation in a 76-year-old woman affected by severe aortic stenosis, previously operated on for "undersized" mitral annuloplasty repair of severe functional mitral regurgitation in dilated cardiomyopathy. No deformation of the nitinol tubing of the CoreValve device (CoreValve, Inc, Irvine, CA), neither distortion nor malfunction nor change of the conformation of the mitral ring occurred. No change in mitral function and regurgitation was evident at echocardiography monitoring, which was performed during the implant.
目前尚无文献报道既往行二尖瓣瓣环修复术的患者行经导管主动脉瓣植入术的有效性和安全性。人们担心经皮主动脉瓣和二尖瓣瓣环成形环之间可能存在干扰。我们报告了 1 例 76 岁女性患者的经皮主动脉自膨式瓣膜植入术经验,该患者患有严重的主动脉瓣狭窄,既往因扩张型心肌病严重功能性二尖瓣反流而行“小瓣环”二尖瓣瓣环成形术。CoreValve 装置(CoreValve,Inc,Irvine,CA)的镍钛诺管既没有变形,也没有扭曲、故障或改变二尖瓣环的形态。在植入过程中进行的超声心动图监测显示二尖瓣功能和反流无变化。
