A 2-year-old boy with an incidental finding of massive cardiomegaly on a chest X-ray was diagnosed with a giant right atrial aneurysm upon further investigation with echocardiography. The patient underwent successful surgical reduction of the right atrium and closure of the patent foramen ovale to prevent thromboembolic complications and to lower the risk of atrial arrhythmias. The resected atrium had paper-thin walls and pathological features of interstitial fibrosis with endocardial thickening.
一名2岁男孩在胸部X光检查时意外发现心脏肿大，经超声心动图进一步检查后被诊断为巨大右心房动脉瘤。该患者成功接受了右心房缩小手术及卵圆孔未闭封堵术，以预防血栓栓塞并发症并降低房性心律失常的风险。切除的心房壁薄如纸，具有间质纤维化和心内膜增厚的病理特征。
