A 59-year-old man with prior coronary artery bypass surgery underwent cardiac catheterization for worsening angina. Angiogram showed severe native coronary artery disease with 2 patent vein grafts. However, a left internal mammary artery graft to the left anterior descending artery was found to have a long lesion (Figure 1). Spasm was excluded by intra-arterial nitroglycerin administration. After discussing the options, optical coherence tomography (OCT)–guided percutaneous intervention was pursued.
Severe atherosclerosis of internal mammary artery is a rare encounter (1); however, despite the lack of pathological validation, we believe this to be the first case in the published data where it was delineated by OCT, which also depicted its similarity to native coronary artery atherosclerosis.
Dr. Ali has reported that he has no relationships relevant to the contents of this paper to disclose.
