A 3-year-old, male neutered, domestic short-haired cat presented for evaluation of respiratory distress. Transthoracic echocardiography revealed a left-to-right shunting ventricular septal defect, a left-to-right shunting patent ductus arteriosus, and a vegetative growth on the aortic valve leaflet consistent with aortic valve endocarditis. Because of poor response to therapy, the owner elected euthanasia, and a necropsy was performed. Gross necropsy examination confirmed the congenital cardiac defects, and aortic valve endocarditis was noted on the echocardiogram. Histopathological examination revealed diffuse interstitial pneumonia and evidence for systemic septic embolism including renal infarcts and brain microabscesses. To the authors' knowledge, this is the first case report of aortic valve endocarditis in a cat in association with congenital cardiac malformations.
一只 3 岁、雄性、已绝育的家短毛猫因呼吸困难就诊。经胸超声心动图显示存在左向右分流的室间隔缺损、左向右分流的未闭动脉导管，以及主动脉瓣叶上的一个赘生物，符合主动脉瓣心内膜炎。由于治疗反应不佳，主人选择对其实施安乐死，并进行了解剖检查。大体剖检检查证实存在先天性心脏缺陷，超声心动图显示主动脉瓣心内膜炎。组织病理学检查显示弥漫性间质性肺炎和全身性脓毒性栓塞的证据，包括肾梗死和脑微脓肿。据作者所知，这是首例与先天性心脏畸形相关的猫主动脉瓣心内膜炎病例报告。
