Abstract：
Double outlet right atrium is a rare congenital cardiac abnormality that has been previously reported in humans and cats, but not in dogs. A double outlet right atrium is typically characterized by the presence of a leftward deviation of the interatrial septum and atrial septal defect. Therefore, the right atrium drains into both ventricles. The unique features consistent with double outlet right atrium were identified by transthoracic echocardiography and computed tomography in a puppy. This case report describes the clinical, echocardiographic, and tomographic findings of a five-month-old Cocker Spaniel diagnosed with this rare congenital abnormality.

双出口右心房是一种罕见的先天性心脏异常，先前已在人类和猫中报道过，但不是在狗。双出口右心房的典型特征是存在向左的房间隔和房间隔缺损。因此,右心房流入两个心室.通过经胸超声心动图和计算机断层扫描在小狗中鉴定出与双出口右心房一致的独特特征。此病例报告描述了临床，超声心动图,5个月大的可卡猎犬被诊断患有这种罕见的先天性异常。
