A giant sinus node artery fistulizing to superior vena cava presenting with steal phenomenon: An unusual case report

Abstract

Congenital coronary fistulas are rare anomalies. They can be either symptomatic or asymptomatic. Management strategy for coronary fistulas differs depending on the blood f low and symptoms. Nevertheless, it should be considered a serious health problem which may result in unpleasant complications such as congestive heart failure through left-to-right shunt, myocardial ischemia through steal phenomenon, endocarditis, and aneurysmal ruptures. Herein, we present the surgical management of a young female who was referred to our clinic with exercise-induced substernal chest pain and numbness in the left upper extremity caused by a giant sinus node artery fistulizing to the superior vena cava.
