Case Report: Surgical Treatment of High-Flow Coronary Fistulas for the Pulmonary Artery

Abstract Coronary fistulas are rare anomalies that can affect approximately 1% of the population, presenting few specific symptoms, and are often found occasionally in coronary angiography. Here we describe the case of a 61-year-old patient with complaints of precordialgia and dyspnea since adolescence, with late diagnosis of coronary fistulas with drainage to the pulmonary artery, and with unsuccessful percutaneous treatment. Therefore, she underwent open surgery for the correction of the already known fistulas, in addition to the hemangioma involving such vessels, which made the understanding and resolution of this case more complex.
