Anomalous Origin of the Right Coronary Artery Causing Myocardial Ischemia: A Case for a Multimodality Imaging Approach

Figure 4

(a–d) Axial CCTA images demonstrating the anomalous RCA arising from the left coronary cusp and taking an intra-arterial course. The extent of the proximal and mid-vessel is better delineated than in CMR (a). The slit-like configuration of the ostial RCA, as well as the acute angulation of its takeoff, is seen in this en-face coronal view (b). Cross sections of the RCA are shown, demonstrating the intramural portion (c) and just distally (d).
