Left Juxtaposition of the Right Atrial Appendage: Pitfalls in Diagnosis

Figure 4

Noncontrast CMR obtained in axial (a–c), sagittal (d), and coronal views (e). Sequential imaging obtained in 3D Heart Navigator Sequence during systole of the aortic root was performed moving from more cephalad to more caudad. The aortic root is intact, and there is no evidence of aneurysm as suspected on CCT. Instead, the arrows in each image highlight the unusual course of the RAA anteriorly around the root of the aorta extending to the left side and account for the suspected intimal flap previously noted.
