Abstract
BACKGROUND
Intra-atrial right coronary artery (RCA) is a rare and generally asymptomatic anomaly of development of the coronary arteries. This malformation could potentially expose the patient to a catastrophic outcome in the case of injury during interventional or surgical procedures. Currently, only a few case reports and no systematic reviews are available in the literature.
CASE SUMMARY
We report the case of a 54-year-old man with atypical chest pain who underwent multi-detector computed tomography angiography (MDCTA). The exam revealed no significant coronary artery stenoses; however, an intra-atrial course of mid RCA was evident. Medical therapy was administered, and the patient was discharged to home without undergoing a conventional angiography. Previously reported autoptic and clinical cases were retrieved from the PubMed literature database to compare the clinicopathological features of this case.
CONCLUSION
MDCTA depicted the abnormal course of the coronary artery in this patient as an intra-atrial course of the mid RCA. Finding this abnormality was crucial to avoid an inadvertent injury during interventional or surgical procedures.
