Figure 2 Photographs of the patient’s first emergency percutaneous coronary intervention. A: 60%-70% diffuse stenosis in the proximal part of the right coronary artery, approximately 50% stenosis in the middle part, and total occlusion beyond the middle and distal parts; B: After balloon dilation, digital subtraction angiography shows 90% stenosis in the middle and distal parts of the right coronary and 90% stenosis in the distal part; C: Stenosis of the distal right coronary artery has disappeared after injecting 2 mL of nitroglycerin; D: No stenosis in the middle or distal part of the right coronary artery after stent implantation, with Thrombolysis in Myocardial Infarction flow grade 3.
