Primary cardiac tumors are rare, and approximately 90% of them are benign. Myxoma is the most common type of these tumors occurring in the left atrium in 75-85% of cases. The tumor can cause the left atrio-ventricular valve obstruction and embolization phenomenon. Case presentation We reported a case of 54-year-old man with complaints of dyspenea and amnesia. In our patient, transthoracic echocardiography revealed a mass of 28*63 mm attached to the upper intra-atrial septum, which was prolapsing through the mitral valve into the left ventricle during diastole, being indicative of the left atrial myxoma. On examination, he was alert and conversant, and no pathological abnormality was observed in the examination of cardiovascular, gastrointestinal, respiratory, hepatic, renal and nervous systems. After myxoma diagnosis, the tumor was removed under cardiac surgery and discharged under good conditions. In the telephone follow-up after discharge, the patient recovered and did not report the disease and surgery complications.
Patients with cardiac myxoma are usually asymptomatic, but they may have manifestations related to the embolism phenomenon or intracardiac obstruction. Therefore, myxoma may represent an emergency. Surgery should be performed as soon as possible. If surgery is delayed, the patient may suffer from serious and irreversible complications, such as stroke and cardiac arrest.
原发性心脏肿瘤较为罕见，其中约 90%为良性。黏液瘤是这些肿瘤中最常见的类型，约 75-85%发生于左心房。肿瘤可导致左房室瓣阻塞和栓塞现象。
我们报告了 1 例 54 岁男性，主诉呼吸困难和健忘。在我们的患者中，经胸超声心动图显示一个 28*63mm 的肿块附着在上腔房间隔，在舒张期通过二尖瓣脱垂进入左心室，提示左心房黏液瘤。检查时，患者神志清醒，交谈自如，心血管、胃肠道、呼吸、肝、肾和神经系统检查未见病理性异常。黏液瘤诊断后，在心脏手术下切除肿瘤，并在良好的情况下出院。出院后的电话随访中，患者恢复良好，未报告疾病和手术并发症。
心脏黏液瘤患者通常无症状，但可能有与栓塞现象或心内阻塞相关的表现。因此，黏液瘤可能代表一种急症。应尽快进行手术。如果手术延迟，患者可能会遭受严重且不可逆转的并发症，如中风和心脏骤停。
