Cardiac myxomas are the most common primary cardiac tumor and are predominantly found in the left atrium. They are biologically benign but carry the risk of embolization.
A 46-year-old man had an incidental finding of a giant right atrial mass. Despite being asymptomatic, the cardiac mass measured 8.6 cm × 5.7 cm and masked severe tricuspid regurgitation. Diagnosis was confirmed on transesophageal echocardiography, and surgical removal of the mass with tricuspid valve repair was performed. Pathologic analysis confirmed the mass to be a cardiac myxoma.
Right atrial myxomas can vary in size and can be quite large, with a mean size of about 5 to 6 cm. Larger myxomas typically present with signs and symptoms related to tricuspid valve obstruction.
TAKE-HOME MESSAGE: This case reports a giant right atrial cardiac myxoma, presenting without hemodynamic compromise and demonstrating the importance of recognizing the mass effect on cardiac valves.
心脏黏液瘤是最常见的原发性心脏肿瘤，主要位于左心房。它们在生物学上是良性的，但有栓塞风险。
一名46岁男性偶然发现右心房有一个巨大肿块。尽管无症状，但心脏肿块大小为8.6 cm×5.7 cm，掩盖了严重的三尖瓣反流。经食管超声心动图确诊后，对肿块进行了手术切除并修复三尖瓣。病理分析证实肿块为心脏黏液瘤。
右心房黏液瘤大小不一，可能相当大，平均大小约为5至6 cm。较大的黏液瘤通常表现出与三尖瓣梗阻相关的体征和症状。
本病例报告了一例巨大的右心房心脏黏液瘤，无血流动力学损害，显示了认识肿块对心脏瓣膜影响的重要性。
