Classic cor triatriatum is rarely found in adults. Preoperative assessment of classic cor triatriatum in a 22 year old man without symptoms by three dimensional echocardiography was more informative than transoesophageal echocardiography or magnetic resonance imaging, which both showed only a small hole in the membrane separating the accessory atrium from the true left atrium. The size of the hole indicated a strong likelihood that symptoms would develop in this patient. Dynamic three dimensional echocardiography, however, showed a long wide hole in the separating membrane. This finding was consistent with the absence of symptoms in this patient. Symptom free patients with moderate obstruction do not need early surgical correction.

典型三房心在成年人中很少见。一名22岁无症状男性的典型三房心经三维超声心动图术前评估，比经食管超声心动图或磁共振成像提供的信息更多，后两者仅显示分隔副心房与真正左心房的隔膜上有一个小孔。该小孔的大小表明该患者很可能会出现症状。然而，动态三维超声心动图显示分隔隔膜上有一个长而宽的孔。这一发现与该患者无症状相符。无症状且梗阻程度中等的患者无需早期手术矫正。
