Figure 1 Coronary angiograms. A: Left anterior oblique caudal view; B: Right anterior oblique cranial view. The coronary angiograms show the left main coronary artery with severe ostial stenosis and left anterior descending artery (LAD) with a diffuse lesion in the mid segment and right coronary artery from the midportion of the LAD.

Figure 2 Aortography (left anterior oblique view) reveals a blunt right and noncoronary sinus without coronary origin.

Figure 3 Coronary angiograms after percutaneous coronary intervention. A: Caudal view; B: Right anterior oblique cranial view. The images show excellent stent expansion and no dissection in the left main coronary artery ostia, the mid segment of left anterior descending artery, and right coronary artery with thrombolysis in myocardial infarction grade 3 flow.
