The clinical, electrocardiographic, radiographic, and two-dimensional, M-mode and Doppler echocardiographic findings of five cases of canine ostium secundum type atrial septal defect (ASD) are described. The atrial septal anomaly was associated with other congenital cardiac abnormalities in two dogs: ventricular septal defect in one case and tricuspid dysplasia in the other. ASD was found in addition to dilated cardiomyopathy and suspected atrial thrombosis in one geriatric dog, but was the only cardiac abnormality detected in the remaining two dogs. Colour Doppler imaging facilitated the diagnosis of ASD in all subjects. The long-term prognosis for dogs with isolated and small-sized ASD is usually good, but can be compromised by the presence of concurrent congenital or acquired cardiac diseases.
描述了5例犬继发孔型房间隔缺损（ASD）的临床、心电图、放射影像学以及二维、M型和多普勒超声心动图检查结果。在2只犬中，房间隔异常与其他先天性心脏异常相关：1例为室间隔缺损，另1例为三尖瓣发育异常。在1只老年犬中，除扩张型心肌病和疑似心房血栓形成外还发现了ASD，但在其余2只犬中ASD是唯一检测到的心脏异常。彩色多普勒成像有助于所有受试对象的ASD诊断。孤立性小尺寸ASD犬的长期预后通常良好，但可能会因并发先天性或后天性心脏病而受到影响。
