Myxomas are the most common primary cardiac tumours. They are usually benign and have variable presentation. Although rare, atrial myxomas are the most important cardiac tumours to diagnose, as they have an excellent prognosis following surgical excision. We report a 56 year old man who presented with features of both right and left heart failure. Ausculation of the heart revealed an apical mid diastolic murmur. Two-dimensional colour flow Doppler echocardiography revealed a pedunculated left atrial myxoma that prolapsed into the mitral valve orifice in diastole producing functional mitral valve stenosis. The patient underwent a successful surgical excision of the tumour. The diagnosis and management of atrial myxomas is reviewed.
黏液瘤是最常见的原发性心脏肿瘤。它们通常为良性，临床表现多样。虽然罕见，但心房黏液瘤是最重要的需诊断的心脏肿瘤，因为手术切除后预后良好。我们报告一名56岁男性，表现为左右心力衰竭的症状。心脏听诊发现心尖部舒张中期杂音。二维彩色多普勒超声心动图显示一个有蒂的左心房黏液瘤，在舒张期脱垂入二尖瓣口，导致功能性二尖瓣狭窄。该患者成功接受了肿瘤手术切除。本文对心房黏液瘤的诊断和治疗进行了综述。
