Abstract A 65-year–old man with effort angina pectoris underwent percutaneous coronary intervention of the proximal right coronary artery. The lesion was dilated with a bare-metal stent under wire protection of the conus branch (CB). However, the jailed CB was occluded. Electrocardiogram with conventional precordial leads (V1 through V6 ) accompanied with the supplementary leads (V1 ⁎ through V6 ⁎) positioned 1 intercostal space higher showed marked ST elevation in V1 through V3 that was more prominent in V1 ⁎ through V3 ⁎. The 64–multidetector-row computed tomographic coronary angiography showed recanalization of the CB located just in the center of the V1 ⁎, V2 ⁎, V1 , and V2 electrodes.
