Sinus Node Artery Fistula
A decision was made with the patient to remove the fistula because of the risk of endocarditis, an increase in left-to-right shunt flow, and the risk of coronary steal. The patient tolerated the procedure extremely well and remained in sinus rhythm after surgery. A sinus node artery fistula is a very rare condition. The exact cause of the fistula in this patient is most likely congenital, because the patient had no history of major trauma or endocarditis.
