We report a case of a left atrial mass in a 62-year-old patient with no relevant past history. He presented with dyspnea of 1 year duration. Clinical examination revealed a blood pressure of 130/82mmHg, a heart rate of 80 beats per minute. The heart sounds S1 and S2 were normal with no added sounds. Electrocardiogram showed a normal sinus rhythm at 78 beats per minute with premature ventricular contractions. Two dimensional echocardiography revealed a large mobile mass attached to the interatrial septum occupying the most of the left atrium and prolapsing into the left ventricle during diastole. There was dilatation of the right atrium and right ventricle with elevated pulmonary artery systolic pressure (85mmHg). The mean transmitral pressure gradient was 5.5mmHg. The mass was compatible with a myxoma. The patient was sent for surgical resection of the mass but this could not be performed due to financial constraints.
我们报告了一例 62 岁患者的左心房肿块，该患者无相关既往病史。他以 1 年呼吸困难为主要表现。临床检查发现血压为 130/82mmHg，心率为 80 次/分钟。第一心音和第二心音正常，无附加音。心电图显示正常窦性节律，心率为 78 次/分钟，有室性期前收缩。二维超声心动图显示，一个大的活动肿块附着于房间隔，占据了左心房的大部分，并在舒张期时突入左心室。右心房和右心室扩张，肺动脉收缩压升高（85mmHg）。平均二尖瓣跨瓣压力梯度为 5.5mmHg。该肿块符合黏液瘤。患者被转介行肿块切除术，但由于经济限制未能进行。
