Abstract:

Coronary angiography is the best method for the diagnosis of coronary artery fistula. Treatment of asymptomatic coronary-pulmonary fistulas varies according to fistula size, patient age, presence of symptoms, and the profit/loss balance of the interventional procedure. These patients, who are usually asymptomatic, are diagnosed incidentally during coronary computed tomographic angiography or invasive coronary angiography. In the case report, it was aimed to show the rare association of Vieussens ring and pulmonary fistula. In this case report, an 82-year-old female patient with exertional dyspnea, hypertension, atrial fibrillation and type 2 diabetes mellitus was included in the study. In the physical examination of the patient, a 3/6 systolic murmur was detected on cardiac auscultation. In the electrocardiography of the patient, atrial fibrillation rhythm was observed at an average heart rate of 80/min. In the coronary angiography of the patient, the main coronary distal plaque, left anterior proximal plaque, normal circumflex and normal right coronary artery were observed. It was observed that developed collaterals originating from the diagonal artery and optus marginal artery extending to the pulmonary artery and collaterals originating from the right coronary artery conus branch anastomose (Vissuens arterial ring) with collaterals extending to the pulmonary arteries.
