Coronary-to-bronchial artery fistula in a patient with multivessel coronary disease treated by percutaneous coronary intervention.

We describe the case of a 78-year-old patient, admitted to our hospital with an acute coronary syndrome. Coronary angiography showed multivessel coronary artery disease and an anomalous coronary vessel branching from the right coronary artery. After successful percutaneous revascularization and discharge, the anomalous vessel was diagnosed by contrast enhanced 64-multidetector computed tomography as a coronary-to-bronchial fistula. Since the patient was asymptomatic, conservative treatment was selected.
