Abstract :
Coronary artery disease (CAD) is a known potential complication of thoracic radiation treatment that typically affects the proximal
segments of the coronary arteries, requiring coronary artery bypass grafting (CABG). We present a case of acute coronary
syndrome occurring in a 57-year-old man with prior thoracic radiation therapy following resection of a chest wall
chondrosarcoma. Coronary angiogram demonstrated significant areas of stenosis in the left main coronary artery (LMCA) and
ostial left anterior descending (LAD) coronary artery. The patient was also found to have atretic bilateral internal mammary
arteries as a consequence of his radiation therapy, rendering them unsuitable as grafts. Percutaneous coronary intervention
(PCI) was thus performed with a successful outcome. To our knowledge, this is the first case of radiation-induced CAD of the
LMCA with atretic internal mammary arteries treated successfully with PCI.
