          Summary

          Background:

          Intra-atrial course of the right coronary artery is a rare anomaly. The recognition of this entity is crucial to avoid potential hazards related to vessel injury during interventional procedures such as right heart catheterization, pacemaker implantation, invasive electrophysiology testing or atrial flutter ablation.

          Case Report:

          We present a case of a 62-year old female with paroxysmal atrial flutter and atrial fibrillation, whose cardiac computed tomography revealed an anomalous course of the right coronary artery through the right atrium.

          Conclusions:

          Cardiac computed tomography examination enables an accurate assessment of morphology and location of the anomalous vessel course.

          Anomalous intracavitary right coronary artery shown by cardiac CT: a potential hazard to be aware of before various interventions.

          Intracavitary right coronary arteries (RCAs) are uncommon (incidence of 0.09%-0.1%), having previously been reported nearly exclusively in autopsy series. However, more recently this entity has been detected prospectively by noninvasive cardiac computed tomography. Because many interventional procedures, including pacemaker placement and atrial flutter ablation, may be influenced by the presence of an intracavitary RCA, this entity is important to recognize. We report two cases of intracavitary right coronary artery discovered prospectively by cardiac computed tomography. In one of these cases, interventional management was altered based on our findings.

            Case report: Intra-atrial course of right coronary artery: Evaluation by dual-source CT

            We report a case of an anomalous course of the right coronary artery (RCA) through the right atrium, which was evaluated using dual-source CT angiography. There have been a few cases described previously in literature, but most of them were found either during surgery or at autopsy. Although this variant is clinically benign, it has significant consequences during interventional procedures or bypass surgery.
