A 67-year-old female patient underwent a left ventricular aneurysmectomy and mitral valve replacement for ischemic cardiomyopathy. The replacement was done through left ventricle rather than left atrium. She had heart failure of NYHA class IV despite aggressive medical therapy. Preoperative examination revealed a left ventricular aneurysm and mitral regurgitation of grade II with markedly reduced ventricular function (LVEF 17%). Mitral valve replacement through left ventricle preserving chorda of the mitral valve is a promising method to eliminate regurgitation and shorten the cardiac ischemic time.
一名67岁女性患者因缺血性心肌病接受了左心室动脉瘤切除术和二尖瓣置换术。置换是通过左心室而非左心房进行的。尽管进行了积极的药物治疗,她仍处于纽约心脏协会(NYHA)IV级心力衰竭。术前检查发现左心室动脉瘤和二尖瓣反流二级,心室功能明显降低(左心室射血分数[LVEF]为17%)。通过保留二尖瓣腱索的左心室途径进行二尖瓣置换是一种有望消除反流并缩短心脏缺血时间的方法。
