An 11-month-old, 3 kg, female domestic shorthair cat was referred to evaluate cardiac structure and function. Echocardiography revealed the membrane dividing the left atrium into two chambers, a large defect in the lower part of the atrial septum, and turbulent blood flow from the distal left atrium into the right atrium. These findings suggested cor triatriatum sinister (CTS) with incomplete atrioventricular septal defect (AVSD). The cat was treated with medications for management of congestive heart failure. In the end, she died from right-sided heart failure 17 months after the initial presentation. At necropsy, a fibromuscular membrane with a round orifice in the left atrium and an ostium primum defect were confirmed, and the definitive diagnosis of CTS with incomplete AVSD was made. To our knowledge, this study presents the first case report of CTS with incomplete AVSD in a cat.
一只11个月大、体重3千克的雌性家养短毛猫被转诊来评估心脏结构和功能。超声心动图显示有一个将左心房分为两个腔室的隔膜、房间隔下部的一个大缺损以及从左心房远端到右心房的湍流。这些发现提示为左三房心（CTS）合并不完全房室间隔缺损（AVSD）。这只猫接受了治疗充血性心力衰竭的药物治疗。最终，它在初次就诊17个月后死于右心衰竭。尸检时，证实左心房有一个带有圆形孔口的纤维肌性隔膜和一个原发孔缺损，并做出了CTS合并不完全AVSD的明确诊断。据我们所知，本研究呈现了猫CTS合并不完全AVSD的首例病例报告。
