A 14-month-old, female mini rex was referred for a detailed examination because of exercise intolerance with associated dyspnea. The thoracic radiograph demonstrated severe cardiac enlargement and elevation of the trachea. The echocardiography revealed dilatations of the right-side heart and pulmonary artery, and the color flow Doppler echocardiography demonstrated an atrial septum defect with left to right shunt, resulting in a disturbed flow. The rabbit died 19 days after the initial presentation, and a necropsy was performed. At the necropsy, a defect, 5 mm in diameter, was detected in the atrial septum. Based on the location of the defect, an ostium secundum type atrial septal defect was diagnosed. This is the first clinical report of atrial septal defect in rabbits.
一只14个月大的雌性迷你雷克斯兔因运动不耐受伴呼吸困难而被转诊进行详细检查。胸部X光片显示严重的心脏扩大和气管抬高。超声心动图显示右侧心脏和肺动脉扩张，彩色多普勒超声心动图显示房间隔缺损并伴有从左向右分流，导致血流紊乱。这只兔子在首次就诊后19天死亡，并进行了尸检。尸检时，在房间隔发现一个直径5毫米的缺损。根据缺损的位置，诊断为继发孔型房间隔缺损。这是兔子房间隔缺损的首例临床报告。
