A vascular communication between the left coronary artery and the main pulmonary artery (coronary fistula) was incidentally diagnosed in a 3-year-old female Tatran hound during a pre-anesthetic evaluation using echocardiography. Trauma and endocarditis were not suspected given the patient's history, clinical examination, and diagnostic imaging, which could have contributed to the development of this condition. Transthoracic echocardiography revealed dilation of the left coronary ostium, and continuous shunting on color and spectral Doppler was observed and this led to the diagnosis of coronary artery fistula. This diagnosis was confirmed through computed tomography. Coronary artery fistulas are infrequent findings in both humans and animals. According to the authors, this is the first reported clinical case of a congenital fistula between the left coronary artery and the main pulmonary artery in a dog.
在对一只3岁雌性塔特拉猎犬进行麻醉前评估时，通过超声心动图偶然诊断出左冠状动脉与主肺动脉之间存在血管交通（冠状动脉瘘）。根据患者的病史、临床检查和诊断成像，未怀疑有创伤和心内膜炎，而这些情况可能导致了该病症的发生。经胸超声心动图显示左冠状动脉口扩张，彩色和频谱多普勒观察到持续分流，这导致了冠状动脉瘘的诊断。该诊断通过计算机断层扫描得到证实。冠状动脉瘘在人类和动物中均为罕见发现。据作者称，这是首例报道的犬类左冠状动脉与主肺动脉之间先天性瘘的临床病例。
