Post-coronary artery bypass grafting left internal mammary artery to pulmonary artery fistula: a 6 year follow-up following successful surgical division.

We report a case of young male patient who developed left internal mammary artery to pulmonary artery fistula 9 years following the coronary artery bypass grafting operation. The clinical signs and symptoms were very subtle including recurrence of angina and heart murmur. Surgical division of the fistula and re-grafting of blocked coronary arteries resulted in satisfactory long term outcome.
