Abstract
We report our experience of surgical treatment of coronary artery fistula and focus on the electrocardiographic changes that may be seen postoperatively. Between 1988 and 2003, cardiac operations were carried out on 9,487 patients, of whom 21 had a coronary artery fistula. The mean age of these 21 patients was 36.8 ± 4.9 years. The fistula originated from the right coronary artery in 9 cases and from the left side in 12. The fistulous connection was to the right ventricle in 5 patients, to the right atrium in 6, to the pulmonary artery in 8, and to the coronary sinus in 2. There was no operative mortality. Two patients (10%) had nonspecific electrocardiographic changes during the postoperative period. Repeat coronary angiography revealed normal coronary anatomy in both, and their electrocardiograms normalized within 2 months. Patients suspected to have myocardial ischemia related to the surgical procedure, with ST segment depression or T wave abnormalities on the electrocardiogram, should undergo repeat angiography to eliminate the possibility of coronary artery damage.
