Echocardiographic evaluation of coronary artery fistula connecting the right coronary artery to the coronary sinus: a case report.

: Coronary artery fistula is a rare incidental finding during routine cardiac catheterization. It is usually congenital but it may also be a consequence of chest trauma or iatrogenic procedures. Patients may be asymptomatic or experience signs and symptoms of myocardial ischemia. In this article we report a casual echocardiographic finding of a coronary artery anomaly in an asymptomatic patient who underwent successful surgical closure and remained well several years after the procedure.
