Abstract

Recurrent angina pectoris developed in a 59-year-old man 3 years after coronary artery bypass grafting using the left internal mammary artery. Cardiac catheterization showed a fistula between the left internal mammary artery and the pulmonary vasculature. This is an unusual documented case of postoperative internal mammary artery graft to pulmonary vasculature fistula after coronary artery bypass grafting. Division of this fistulous communication resulted in resolution of the patient's angina.
