Abstract

Cardiac myxoma is the commonest primary cardiac tumor, however, the incidence of right atrial myxoma is very rare. We reported a 71-year-old man with a right atrial myxoma, whose main complaint was fever of unknown origin. Definite diagnosis was confirmed by echocardiography and cineangiocardiography. Venacavogram revealed huge mass which occupied greater part of right atrial cavity. Coronary angiogram revealed the feeding artery arising from left coronary circumflex artery and the sign of hypervascularity. Open heart surgery was performed, and a 4.9 x 4.0 x 3.8 cm tumor was found in the right atrial cavity. Pathological examination showed the findings of myxoma. Postoperative clinical course was uneventful.

摘要

心脏黏液瘤是最常见的原发性心脏肿瘤，然而，右心房黏液瘤的发病率非常低。我们报道了一名71岁患有右心房黏液瘤的男性患者，其主要症状为不明原因发热。经超声心动图和心血管造影确诊。腔静脉造影显示巨大肿块占据右心房腔的大部分。冠状动脉造影显示供血动脉起源于左回旋支动脉且有血管增多的迹象。进行了心脏直视手术，在右心房腔内发现一个4.9×4.0×3.8厘米的肿瘤。病理检查显示为黏液瘤表现。术后临床过程平稳。
