Patient Data

Age: 48
Gender: Male

LMCA, LAD, circumflex and RCA are of normal calibre and free of atherosclerotic disease.

The mid RCA takes an intra-atrial course, lying within the lumen of the lower right atrium.

No pulmonary parenchymal, pleural or other abnormality identified in the portion of the thorax imaged.

Case Discussion

In the uncommon anatomic variation of the course of the RCA, the mid and distal segments course through the atrial chamber. The clinical consequence is minimal except during any procedure where a wire is passed into or through the right atrium, which may injury the RCA.
