Intra-atrial course of right coronary artery: A case report

Figure 1 Multi-detector computed tomography angiography showed the anomalous intra-atrial course of the mid right coronary artery. A: Curved planar reformatting showed the entire course of the right coronary artery (RCA) with a mid-segment with an intra-atrial course; B: Volume rendering technique showed the entire course (green line) of the RCA; C: Cross-sectional images showed the intra-atrial segment of the RCA, which was completely surrounded by blood in the right atrium; D: Curved planar reformatting showed the entire course of the RCA with a mid-intra-atrial course of the artery.
