摘要

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.
