Abstract

Coronary artery fistulas (CAF) are considered rare congenital anomalies, characterized by direct communications between the coronary arteries and cardiac chambers or great vessels. Their prevalence is estimated at 0.2% to 0.4% of congenital heart defects. Their etiology is related to abnormalities in embryonic development. The right coronary artery (RCA) and the left anterior descending artery (LAD) are the most common sites of origin. Clinical presentation is variable, ranging from asymptomatic cases to symptoms such as fatigue, dyspnea, palpitations, and chest pain (due to ischemia). Diagnosis is established through imaging methods such as echocardiography, cardiac computed tomography angiography, and coronary angiography. Currently, there are no standardized therapeutic guidelines for the management of CAF due to the rarity of cases. This article aims to report a case of a patient with CAF and complex coronary lesions who underwent coronary angioplasty and fistula embolization concomitantly.
