AbstractLarge aneurysms (> 4 cm) of saphenous vein grafts (SVG) to coronary arteries are a rare complication of coronary artery bypass graft surgery (CABG). A 64-year-old male, status post-CABG 14 years ago, presented with dyspnea and diaphoresis. Pneumonia and non-Q-wave myocardial infarction (MI) were diagnosed. Cardiac catheterization and chest computed tomography demonstrated a 5 x 7-cm aneurysm of a SVG. At the time of surgery, the left internal mammary artery (grafted to the left anterior descending artery) was found to be stretched tautly over the aneurysm, resulting in impaired flow. The aneurysm was successfully resected. This is the first published case implicating a SVG aneurysm as the direct cause of a MI by mass effect.
