case_images: A 12-lead electrocardiogram (EKG) [Figure 1] and serum troponin (Tn) levels were obtained. The patient's EKG showed acute ST-segment elevations in leads II, III, and AVF [Figure 1].
case_images: Cardiac catheterization images showing selective angiograms of the right coronary artery. Circled areas of the right coronary artery correspond to different images of the right coronary artery dissection (middle image, inset, and arrow). There was no evidence of associated right coronary artery thrombosis, and the distal right coronary artery was patent, with no evidence of stenosis or filling defects

case_images: The catheterization demonstrated that the patient's proximal RCA developed a focal dissection [Figure 2], with preserved distal right coronary flow.
case_images: Follow-up cardiac catheterization demonstrates complete resolution of the right coronary artery dissection (areas corresponding to acute abnormalities noted on the initial cardiac catheterization - see Figure 2 - are circled)
