BackgroundCoronary bronchial artery fistulas (CBFs) are rare anomalies, which may be isolated or associated with other disorders.Materials and methodsTwo adult patients with CBFs are described and a PubMed search was performed using the keywords “coronary bronchial artery fistulas” in the period from 2008 to 2013.ResultsTwenty-seven reviewed subjects resulting in a total of 31 fistulas were collected. Asymptomatic presentation was reported in 5 subjects (19 %), chest pain (n = 17) was frequently present followed by haemoptysis (n = 7) and dyspnoea (n = 5). Concomitant disorders were bronchiectasis (44 %), diabetes (33 %) and hypertension (28 %). Multimodality and single-modality diagnostic strategies were applied in 56 % and 44 %, respectively. The origin of the CBFs was the left circumflex artery in 61 %, the right coronary artery in 36 % and the left anterior descending artery in 3 %. Management was conservative (22 %), surgical ligation (11 %), percutaneous transcatheter embolisation (30 %), awaiting lung transplantation (7 %) or not reported (30 %).ConclusionsCBFs may remain clinically silent, or present with chest pain or haemoptysis. CBFs are commonly associated with bronchiectasis and usually require a multimodality approach to be diagnosed. Several treatment strategies are available. This report presents two adult cases with CBFs and a review of the literature.

A coronary-bronchial artery fistula is a very rare congenital anomaly of the coronary artery whose etiology and pathogenesis have not yet been clarified. Most patients with coronary-bronchial fistulas are asymptomatic; however, some patients present with congestive heart failure, infective endocarditis, myocardial ischemia induced by a coronary steal phenomenon, or rupture of an aneurysmal fistula. Furthermore, patients with a coronary-bronchial artery fistula rarely manifest life-threatening hemoptysis due to the associated bronchiectasis. We report herein the case of a patient with a coronary-bronchial artery fistula who had bronchiectasis and a history of massive hemoptysis and myocardial ischemia.

“…1 Despite their rarity, a subset of patients may develop severe complications, including heart failure, ischemia, and arrhythmias. Notably, approximately 30% of adult cases of CAF are associated with coronary atherosclerosis, 3 to occur as distinct and independent phenomena, as illustrated in the case reported by Wandwi et al, 6 and in another case by Brunetti et al, 7 where occlusions in the left circumflex and right coronary arteries coexisted with a fistula connecting the left main and diagonal branch, draining into the pulmonary artery, without apparent interrelation. Conversely, there are instances where CAF and coronary atherosclerosis coexist within the same coronary artery, suggesting a potential interconnection between these two conditions.…”

Coronary artery fistulae (CAF) are a rare anomaly characterized by abnormal connections between a coronary artery and a cardiac chamber or a great vessel, with most patients remaining asymptomatic. Despite being predisposed to severe complications like heart failure, patients with CAF infrequently experience severe stenosis in the coronary artery. This study delineates a case involving a 46-year-old male presenting with a fistula bridging the right coronary artery (RCA) and right atrium (RA), manifesting a pronounced 99% stenosis at the right extremity of the coronary artery proximal to the fistula. Concurrently, the individual exhibits six conventional risk factors: age over 40, male gender, hypertension, diabetes, smoking, and hypertriglyceridemia. Following pharmaceutical intervention, the patient was discharged and subjected to extended follow-up. This case highlights the dual processes of “accelerating damage” and “retarding renewal” in the progression of atherosclerosis. Factors such as shear stress, smoking, and hypertension are posited to expedite endothelial cell damage, while aging and diabetes may impede the renewal and repair of these cells. Together with the concept of secondary atherosclerotic plaque healing, this case prompts the introduction of a “Double Endothelial Healings” hypothesis, proposing a potential pathogenetic mechanism for coronary artery atherosclerosis.
