Giant right atrium (RA) is a rare finding in adults. We report a case of a 53-year-old female with rheumatic heart disease (RHD) previously submitted to two mitral valve replacements. She presented at the emergency room with signs of heart failure. Image studies revealed gross cardiomegaly. Transthoracic echocardiogram showed torrential tricuspid regurgitation, with right chambers enlargement. At chest tomography, the estimated right atrium volume was 1,200 mL. The patient was treated with intravenous diuretics and multiple paracentesis, as well as referred to heart transplantation. Physicians should be aware of this extreme outcome, which can lead to life-threatening complications such as atrial fibrillation and thromboembolism.
巨大右心房在成人中较为罕见。我们报告一例53岁患有风湿性心脏病（RHD）的女性病例，该患者此前已接受两次二尖瓣置换术。她因心力衰竭症状就诊于急诊室。影像学检查显示心脏明显增大。经胸超声心动图显示严重三尖瓣反流，右心房扩大。胸部断层扫描显示右心房估计容积为1200毫升。该患者接受了静脉利尿剂治疗和多次腹腔穿刺引流，并被转诊进行心脏移植。医生应意识到这种极端情况，它可能导致心房颤动和血栓栓塞等危及生命的并发症。
