A 44-year-old male presented to our hospital with exertional dyspnea. Transthoracic echocardiography revealed a large cystic mass in the left atrium obstructing the mitral valve orifice. Transesophageal echocardiography during emergency operation showed a large cystic mass along with a solid part near the stalk. The mass was resected en bloc including the margin of the left atrium around the stalk. His hemodynamics improved immediately after the operation and the patient was discharged shortly with uneventful postoperative course. While intra cardiac cystic mass has some possible pathologies including malignancy, pathological examination of this tumor revealed a myxoma with large hematoma which had probably grown up rapidly. This tumor was successfully eradicated under the guide of both transthoracic and transesophageal echocardiography.
一名44岁男性因劳力性呼吸困难前来我院就诊。经胸超声心动图显示左心房有一个大的囊性肿块，阻塞二尖瓣口。急诊手术期间的经食管超声心动图显示一个大的囊性肿块以及靠近蒂部的实性部分。连同蒂部周围左心房边缘将肿块整块切除。术后患者血流动力学立即改善，术后恢复顺利，不久后出院。虽然心脏内囊性肿块有一些可能的病理情况，包括恶性肿瘤，但该肿瘤的病理检查显示为伴有大血肿的黏液瘤，血肿可能生长迅速。在经胸和经食管超声心动图的引导下，该肿瘤被成功切除。
