Introduction
A coronary arteriovenous fistula (CAF) is a rare anomaly caused by
abnormal communication between a coronary artery and any cardiac cavity
or great vessel.1 While some cases are asymptomatic
and found incidentally, others are associated with symptoms including
heart failure and myocardial ischemia.2,3,4Symptomatic cases such as those with coronary stealing syndrome and
heart failure owing to shunting are indicated for surgery, while
asymptomatic cases with anatomical findings such as aneurysm formation
also require surgery.4,5,6 Although some studies have
reported surgical techniques for CAFs,7,8 few have
reported long-term outcomes following surgical repair of CAFs in adults.
Herein, we report the clinical characteristics, surgical procedures, and
long-term outcomes of 13 patients with CAFs.
