“…This discrepancy with cardiac catheterization could have resulted from the difference in the modality used. In our study, 67% of CPAFs originated from both the right and left coronary arteries, which is in accordance with previous studies using CT (53-59%) (16)(17)(18)(19). The remaining 33% of CPAFs in our study originated from a single coronary artery; 25% of CPAFs originated from the LCA and 8% of CPAFs originated from the RCA.…”

Purpose: To evaluate multi-detector CT (MDCT) coronary angiographic findings of coronary-to-pulmonary artery fistula (CPAF). Materials and Methods:We retrospectively reviewed images of patients with CPAF from the coronary CT angiography (CCTA) database obtained with a 64-channel MDCT between January 2008 and March 2011. We analyzed the CCTA findings for feeding arteries, fistula, association with peripulmonary arterial aneurysms, and the presence of communication between the CPAF and bronchial arteries. Results: Fifty-five of the 15042 (0.37%) patients were diagnosed with CPAFs. The feeding artery was single (n = 18) or multiple (n = 37). The fistula had a single drainage site (n = 54) or multiple drainage sites (n = 1). The mean diameter of the fistulous opening was 2.7 ± 1.4 mm. A peripulmonary arterial aneurysm was present in 24 (44%) patients. Communication between CPAF and bronchial arteries was present in eight (14.5%) patients. Conclusion: MDCT coronary angiography can provide comprehensive morphologic details on CPAF and may help in presurgical or preinterventional planning.

“…During coronary angiography, CAFs are usually discovered as a coincidental finding, with a prevalence of 0.002% in the general population [3,11,14,21,22,23,24,25]. Among patients undergoing coronary angiography, the prevalence of CAFs is approximately 0.05-0.25% [3,14,15,23,26]. In patients undergoing coronary computed tomography angiography, the prevalence of CAFs ranges from 0.4-0.9% [14,15].…”

“…The majority of these fistulas arise from the right coronary artery (RCA) (33-55%) or the left anterior descending artery (35-49%). The circumflex coronary artery is rarely involved (17-18%) [10,11,14,23,27,28,29]. A single origin is the most common form of CAF, ranging from 74 to 90% of cases [3,11,17].…”

“…A single origin is the most common form of CAF, ranging from 74 to 90% of cases [3,11,17]. The left and right coronary systems are simultaneously involved in approximately 4-18% of reported cases [4,7,10,14,17,22,29,30]. CAFs commonly drain into low-pressure structures.…”

Congenital coronary artery fistulas are rare anomalies. As coronary angiography and multidetector computed tomography have become more accessible, they have been increasingly used in the investigation of chest pain and heart failure. Coronary artery fistulas are often an incidental finding, which raises the question of how patients with this condition should be managed. Intervention with either transcatheter closure or surgical closure is often technically possible. Many patients are asymptomatic early after closure. However, follow-up studies have shown post-closure sequelae, such as residual leakage, thrombosis with or without myocardial infarction, and coronary stenosis. Therefore, there has been a shift from intervention towards watchful waiting in asymptomatic patients. In this article, we review the published literature on the natural history and treatment outcomes in individuals with coronary artery fistulas. We present case reports from our clinic and discuss the management of incidental findings of coronary artery fistulas.
