Formation of a coronary artery aneurysm (CAA), especially a giant CAA, after percutaneous coronary intervention for chronic total occlusion (CTO) is a rare complication. Therapeutic approaches include surgical procedure, covered stent, and medical treatment. Here, we report a 47-year-old man readmitted due to chest distress who had undergone right coronary artery CTO recanalization 6 months earlier. Diagnostic coronary artery angiography revealed a giant aneurysm at the stented middle segment of the right coronary artery; it was >20 mm in diameter. This is the first report on a secondary giant CAA after CTO recanalization that was subsequently excluded with deployment of a covered stent.
