A 74‐year‐old man had undergone two‐vessel coronary artery bypass grafting (CABG), 19 years ago, with the left internal mammary artery (LITA) to the left anterior descending artery and the saphenous vein graft (SVG) to the posterior descending artery. In outpatient care, a thoracic aortic aneurysm was suspected by the chest X‐ray. In the computed tomography, appeared the distal arch aortic aneurysm, abdominal aortic aneurysm (AAA), and giant right coronary artery aneurysm (rCAA). The diameter of rCAA was 70 mm and it oppressed the right atrium and ventricle of the heart. The patient was referred to our hospital. After the initial treatment of distal arch aneurysm and AAA, surgical treatment for the rCAA was performed. The rCAA was resected completely and CABG with new SVG was performed without cardiopulmonary bypass. The histopathology of rCAA wall revealed that the etiology was an atherosclerotic change. The postoperative course was good, the oppressed right heart system was released and the hemodynamics of the tricuspid valve showed improvement.
