Acute coronary syndrome on non-electrocardiogram-gated contrast-enhanced computed tomography

Figure 18 Corresponding invasive coronary angiography in acute coronary syndrome of right coronary artery complicated with anterior old myocardial infarction. Same patient as Figure 17. A: Invasive coronary angiography showed total occlusion in the mid site of the right coronary artery (arrowhead); B: Subsequent percutaneous coronary intervention was performed by balloon angioplasty and stent implantation. C: Invasive coronary angiography also showed 75% stenosis in the proximal site of the second diagonal branch (arrow). RCA: Right coronary artery; LAD: Left anterior descending artery; D2: Second diagonal branch.
