Figure

• 

  Figure 1 Twelve-lead electrocardiogram showing ST-segment elevations in leads V1-3 without reciprocal change.

• 

  Figure 2 Electrocardiogram after percutaneous coronary intervention to the mid-LAD artery lesion showed improvement in ST-segment elevations in the precordial leads.LAD = left anterior descending.

• 

  Figure 3 Left coronary angiograms showing an anomalous origin of the RCA from the mid-LAD artery with a significant stenosis of the RCA ostium (A, B). Left coronary angiograms showing successful revascularization at the bifurcation site between the LAD artery and the RCA (C, D).LAD = left anterior descending; RCA = right coronary artery.

• 

  Figure 4 Three-dimensional computed tomography coronary angiographic images revealing an anomalous origin of the RCA from the LAD artery (A, B), and showing patent stents at the bifurcation site between the LAD artery and the RCA (C).LAD = left anterior descending; RCA = right coronary artery.
