“…CAFs are defined as abnormalities of termination. There is abnormal direct communication between one or more coronary arteries with another vessel (also called coronary-vascular fistulas) or a cardiac chamber (called coronary-cameral fistulas) bypassing the myocardial capillary network [2,3,4,5,6,7,8]. This is in contrast to abnormalities of origin (i.e., anomalous coronary arteries or arteries arising from the pulmonary artery).…”

“…They comprise 13-50% of congenital coronary artery anomalies [3,5,9,10,11,12]. Communications between the coronary arteries and the cardiac chambers are thought to develop during coronary artery development.…”

“…CAFs can also be iatrogenic, occurring after percutaneous coronary intervention, permanent pacemaker placement, cardiac surgery, coronary artery bypass grafting, valve replacement, and repeated myocardial biopsies in cardiac transplantation. Thoracic trauma can also lead to CAFs [2,5,19,20]. Differential diagnosis of CAFs includes systemic arteriovenous fistula, patent ductus arteriosus, pulmonary vein stenosis, an anomalous left coronary artery from the pulmonary artery, pulmonary artery fistula, ruptured sinus of Valsalva aneurysm, and aortopulmonary window [5,11,14,33].…”

“…When the myocardium thickens, a sinusoidal system with trabeculation of the chamber walls is formed, which minimizes diffusion distances [13]. Congenital CAFs within a cardiac cavity are believed to be due to failure of regression of the intramyocardial trabecular sinusoidal system [5,14,15,16,17]. …”

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.

ObjectiveTo evaluate the natural course of coronary-to-pulmonary artery fistula (CPAF) detected on coronary computed tomography angiography (CCTA) and to propose potential treatment strategies.Materials and MethodsIn this retrospective multicenter study, we assessed the CCTA reports of 188 CPAF patients evaluated between March 2009 and June 2016. Fifty-seven patients were excluded because their follow-up (FU) periods were less than 2 years. Information regarding demographic characteristics, past history, treatment method, and the occurrence of major adverse cardiac events (MACE) during the FU period was collected. We analyzed the morphologic features of CPAF and the various factors associated with surgical treatment. Patients who had undergone FU CCTA after being diagnosed with CPAF were assessed for the presence of morphological changes on FU imaging.ResultsThe median age of the study population was 63.0 years (range, 57.0–72.0 years), and the median FU period was 5.72 years (range, 4.08–6.96 years). The most common origin of the CPAF was both coronary arteries in 76 (58.0%) cases. An aneurysm or aneurysms was/were present in 41 (31.3%) cases. Fifty-four (41.2%) fistulas were less than 2 mm in size. Eight patients underwent surgery, and 123 (93.9%) patients received optimal medical treatment (OMT). The fistula size was significantly different between the two treatment groups (p = 0.013) and was the only factor associated with surgical treatment (odds ratio = 1.14, p = 0.021). Only one patient in the OMT group reported MACE during the FU period due to preexisting coronary artery disease. Twenty-nine patients (22.1%) underwent FU CCTA after CPAF diagnosis, with a median FU period of 3.81 years. None of the patients in the OMT group demonstrated morphological changes in the CPAF on FU imaging.ConclusionMost CPAFs identified on CCTA have a favorable prognosis. Observation with OMT is usually an appropriate strategy. Fistula size is a possible determinant for surgical treatment.
