“…3,4 According to previous studies, CAF arises from the RCA in 50% of patients, from the LCA in 42% of patients and from both RCA and LCA in 5% of patients; the most common drainage site is the right ventricle. [6][7][8] In contrast to previous findings, we observed that most CAFs originated from either LCA or both LCA and RCA, and that the most common drainage site was the main pulmonary artery.…”

Conclusion: Coronary-pulmonary artery fistula in adults was found more often than in previous studies. CAF commonly originates from LCA or both LCA and RCA in adults. DSCT is a robust tool for investigating the origin, course and drainage site of CAF and coexistent abnormalities. Advances in knowledge: A large adult patient cohort who underwent DSCT angiography was reviewed to assess CAFs. Coronary-pulmonary artery fistula in adults was found more often than in previous studies. CAF was observed to originate from the LCA or both coronary arteries in adults. DSCT could clearly depict the fistula origin, course, drainage site and coexisting abnormalities. Conventional angiography results, treatments and followup DSCT images were analysed.Coronary artery fistulas (CAFs) are anomalous connections of the coronary arteries. The phenomenon was first described in 1865 by Krause. 1 CAF is considered as a major coronary anomaly by Ogden's classification.2 Most CAFs are congenital. CAFs have an estimated prevalence of 0.002% in the general population; however, they are present in 0.05-0.25% of patients who undergo coronary angiography.3-5 The traditional diagnosis tool for CAFs is conventional angiography. With the advent of 64-slice multidetector CT in chest and cardiac imaging, the number of incidentally found CAFs has been increasing. The advanced electrocardiogram (ECG)-gated technique of dual-source CT (DSCT) could provide high diagnostic accuracy for the assessment of coronary artery disease.According to prior studies, CAF arises from the right coronary artery (RCA) in approximately 50% of patients. [6][7][8] In particular, 70% of the CAFs in children (mean age, 2.9 years) originated from the RCA. 9 In this study, we focused on adult patients. A large cohort of adult patients who underwent DSCT angiography was reviewed to assess CAFs. The CAFs and coexisting abnormalities were analysed. METHODS AND MATERIALS PatientsA total of 17,548 patients who were suspected of having coronary artery disease underwent contrast-enhanced CT angiography (CCTA) from January 2008 to October 2013 in Peking Union Medical College Hospital, Beijing, China. The CCTA reports and images were retrospectively reviewed. Four experienced radiologists reviewed the axial, maximum intensity projection and volume rendering technique images of all 17,548 patients through the picture archiving and communication system. All the images were reviewed only once because of the large amount of work.

“…Most of the times, literature alludes fistula arising from RCA to be dominant. However, certain studies had also demonstrated both from RCA and LCA to be equal [8] [36] [37]. Majority of cases are incidental findings on the course of investigation secondary to other disease, hence, the clinical …”

Coronary artery fistula (CAF) is known be a rare defect of coronary artery. When there is an abnormal pre-capillary communication between single or multiple branches of the coronary artery and any of the cardiac chambers or great vessels, it is designated as CAF. It can be found in both congenital and acquired form. Congenital origin of fistula occupies higher percentage compared to the acquired one. A wide variety of imaging modalities have been lunched to provide the best possible way to access and treat the defect. With regard to the assessment of the coronary artery fistula, trans-thoracic Doppler echocardiography and multi-slice CT (MSCT) angiography have commendable role, however, MSCTA comes in the leading position.

“…Coronary artery fistula (CAF) is considered an embryologic persistence of primitive intratrabecular spaces which allows the developing coronary artery to communicate with the other cardiac chambers or vascular structures (1). It is observed in 0.05% to 0.25% of coronary angiographic studies (2), most of which drain into a right heart chamber or into the pulmonary artery (3,4), while a congential right coronary artery (RCA) into a left heart chamber is less frequent (5).…”

A coronary artery fistula between a coronary artery and a cardiac chamber is a rare condition. We reported a case of right coronary artery fistula to the left ventricle in a 57-year-old man who had 2-year history of chest pain and exercise dyspnea without significant coronary atherosclerosis with abnormal left ventricular size and function. It was important to recognize this anomaly and our experience showed that transcatheter occlusion of coronary artery fistula was a safe and effective procedure in the presence of symptoms of congestive heart failure, significant left-to-right shunt or refractory to medical treatment.
