Background: Coronary artery fistula of the left circumflex is a rare subset of coronary anomaly among with congenital heart disease, and treatment is focused on symptoms of patients, which reflects hemodynamic compromise.
Study case: a case of a 53 year old female who presented with chest pain.
Discussion: Our study findings revealed ischemia in ECG with findings of coronary artery fistula with no stenotic vessels and a normal myocardial scan subsequentlyunderwent transcatheter coiling of the fistula, with remarkable improvement.
Conclusion: Congenital anomalies of the coronaries render complications, and surgical correction is necessary; however, contemporary studies have considered transcatheter techniques, which are debatable. A clinical decision to address the symptoms should be undertaken to prevent further sequelae to the pathologic development of the anomalous coronary.
