Secondary coronary artery ostial lesions: Three case reports

Figure 2 Coronary angiography and aortic computed tomography manifestations of Case 2. A: Coronary angiography (CAG) showed right coronary artery (RCA) ostium occlusion and RCA sinus aneurysm; B: After the operation, CAG showed that the distal blood flow of the RCA recovered from thrombolysis in myocardial infarction grade 2; C: Aortic computed tomography (CT) showed an aneurysm arising from the right coronary sinus, which caused severe stenosis of the RCA ostium; D: Aortic three-dimensional CT reconstruction showed an aneurysm arising from right coronary sinus, which caused severe stenosis of the RCA ostium. RCA: Right coronary artery.
