A 6-year-old female neutered Turkish Angora cat was referred due to tachypnoea. The patient was diagnosed with cardiomegaly at a local hospital during a health screening two years ago. Tachypnoea occurred one year ago. On physical examination, the patient presented with a respiratory rate of 72 breaths per minute and a systolic blood pressure of 70 mmHg. Thoracic radiographs revealed severe cardiomegaly, left atrium (LA) enlargement, right atrium (RA) enlargement, right ventricular enlargement, and dilation of pulmonary arteries and veins. An alveolar pattern was identified in the right and left cranial lung lobes. Echocardiography revealed a membrane that divided the LA into two chambers, a defect in the lower atrial septum, and elongation of anterior or posterior tricuspid valves (TV). However, septal TV was not observed. During systole, blood flow from LA to RA was confirmed through a defect in the atrial septum. During diastole, blood flow from LA to left ventricular was confirmed. These findings suggest cor triatriatum sinister (CTS) with partial atrioventricular septal defect (AVSD). This report describes echocardiographic diagnosis of CTS with partial AVSD in a cat.
一只6岁已绝育的土耳其安哥拉母猫因呼吸急促前来就诊。该患者两年前在当地医院进行健康筛查时被诊断为心脏肥大。呼吸急促于一年前出现。体格检查时，患者呼吸频率为每分钟72次，收缩压为70毫米汞柱。胸部X光片显示严重心脏肥大、左心房（LA）扩大、右心房（RA）扩大、右心室扩大以及肺动脉和肺静脉扩张。在左右肺叶的颅侧发现肺泡样病变。超声心动图显示有一个膜将左心房分为两个腔室，房间隔下部有缺损，三尖瓣（TV）前叶或后叶延长。然而，未观察到间隔三尖瓣。在收缩期，通过房间隔缺损证实有血液从左心房流向右心房。在舒张期，证实有血液从左心房流向左心室。这些发现提示为左三房心（CTS）合并部分房室间隔缺损（AVSD）。本报告描述了一只猫的左三房心合并部分房室间隔缺损的超声心动图诊断。
