An 83-year-old man with acute inferior wall myocardial infarction underwent successful percutaneous coronary intervention for right coronary artery. Subsequent echocardiography 3 days later showed an incidental huge cardiac chamber compressing left atrium. The chamber was found to have a narrow neck connecting with left ventricle, suggestive of a pseudoaneurysm. Real-time 3-dimensional echocardiography could clearly demonstrate the spatial relationship between pseudoaneurysm and corresponding cardiac chambers, and its precise location and the orifice of pseudoaneurysm. A myocardial break-out point resembling a bird beak with a flap could also be clearly seen and quantified by real-time 3-dimensional echocardiography. This patient underwent surgical resection and the serial follow-up remained uneventful.
一名83岁患有急性下壁心肌梗死的男性接受了右冠状动脉的成功经皮冠状动脉介入治疗。3天后的后续超声心动图显示意外发现一个巨大的心腔压迫左心房。发现该心腔有一个与左心室相连的狭窄颈部，提示为假性动脉瘤。实时三维超声心动图能够清晰地显示假性动脉瘤与相应心腔之间的空间关系、其精确位置以及假性动脉瘤的开口。实时三维超声心动图还能清晰地看到并量化一个类似带有瓣叶的鸟嘴状心肌破裂点。该患者接受了手术切除，系列随访情况良好。
