It is well known that mobile or large left atrial myxoma may lead to valve obstruction and insufficiency, and affect transmitral valve flow. A 50-year-old woman with a huge left atrial myxoma occluding the mitral valve was reported. The tumor was diagnosed by preoperative echocardiogram and mitral regurgitation was minimum. During the operation and after the myxoma resection, a severe mitral regurgitation, which was not observed during the preoperative echocardiogram, was noticed. Mitral valve defect was corrected by an annuloplasty ring, and the patient had an uneventful recovery. Our case suggests that careful evaluation of mitral valve during a myxoma resection operation is recommended.
众所周知，活动的或巨大的左心房黏液瘤可能导致瓣膜梗阻和关闭不全，并影响二尖瓣血流。本文报道了一名50岁女性，患有巨大的左心房黏液瘤阻塞二尖瓣。该肿瘤通过术前超声心动图诊断，二尖瓣反流轻微。在手术过程中及黏液瘤切除术后，发现了术前超声心动图未观察到的严重二尖瓣反流。通过瓣环成形环纠正二尖瓣缺损，患者恢复顺利。我们的病例提示，在黏液瘤切除手术中建议仔细评估二尖瓣。
