AbstractA 39-year-old man was admitted because of cardiac arrest. Emergent coronary angiography revealed a preserved coronary blood flow; however, multiple-row detector computed tomography (MDCT) revealed that the proximal right coronary artery (RCA) was running inside the aortic wall, creating proximal stenosis without atherosclerotic changes. Surgical intervention with unroofing was performed; however, postoperative stenosis of the proximal RCA required additional coronary artery bypass grafting (CABG). Intraoperative findings during CABG did not reveal hematoma or coronary dissection. However, MDCT one year after CABG depicted improvement of the RCA and graft stenoses, suggesting that the post-unroof stenosis may have been caused by an inflammatory reaction after surgical intervention.
