Abstract
BACKGROUND: Coronary artery ectasia (CAE) is a rare condition that is characterized by the excessive diffuse dilatation of the coronary arteries by 1.5 times in diameter compared to adjacent coronary arteries. The giant CAE is even rarer and life-threatening. CASE PRESENTATION: A 34-year-old female patient was admitted to our centre with three months history of vague chest pain that worsened gradually. The CT scanner confirmed that there were two giant aneurysmal sacs in the right coronary artery (RCA). The first sac was 32 × 36 mm in size and located in the proximal RCA, the second one containing thrombus in the middle RCA with a size of 43 × 30 mm. The patient was successfully treated by aneurysmal resection and concomitant coronary artery bypass. CONCLUSION: Giant coronary artery ectasia is a rare clinical condition and very dangerous for patients unless properly treated. We successfully treated a case of giant right coronary artery ectasia with favorable outcome.
