A four-year-old German shepherd mixed-breed dog was presented with an asymptomatic heart murmur. An atrial septal defect associated with tricuspid and mitral dysplasia (atrioventricular canal defect) was diagnosed. The pulmonary to systemic blood flow ratio was in the range of 2.5:1 (Qp:Qs ratio). Echocardiography and flow pattern across the valves as well as the direction of the shunt allows a better description of the physiopathological consequences of this rare congenital heart disease. Additionally, an Ostium Secundum Type interatrial septum defect was found at necropsy.
一只四岁的德国牧羊犬混血犬被发现有心脏杂音但无症状。诊断为伴有三尖瓣和二尖瓣发育异常的房间隔缺损（房室管缺损）。肺循环与体循环血流量之比在2.5:1范围内（Qp:Qs比值）。超声心动图、瓣膜血流模式以及分流方向有助于更好地描述这种罕见先天性心脏病的生理病理后果。此外，尸检时发现了继发孔型房间隔缺损。
