Figure 3 Coronary angiography, right coronary artery. A: Before surgery, the stenosis in the proximal and middle segments was about 50%, the stenosis in the middle segment was limited by 50%, and the stenosis in the middle and middle segments was 40%-50%. Localized eccentric stenosis in the distal segment is about 80%. Visible posterior descending artery and posterior branch of left ventricle emissions; B: After drug balloon dilation percutaneous transluminal coronary angioplasty treatment, the lumen showed significant improvement after dilation, with visible A-type dissection and thrombolysis in myocardial infarction III blood flow.
