Figure 1
Coronary artery angiography showed severe diffuse stenosis of the LAD and old MI of the LCx with a collateral flow from the LAD to the LCx (a, b). During the PCI, coronary perforation of the LAD occurred (c), and the covered stent was implanted, but it jailed the septal and two large diagonal branches (d).
