Coronary artery perforation grade III following PCI and unusual stent graft delivery system

Coronary perforations are rare but viscious complications of PCI procedures. Ellis type III coronary artery perforation represents  most severe form and demand urgent  solution . It is often necessary to perform pericardiocentesis  and multiple interventional techniques to seal the perforation. Polytetrafluoroethylene (PTFE)-covered stent implantation became one of the most often used percutaneous solutions, but disadvantages are high profile and low flexibility of device. In our case, we tried to improve deliverability of PTFE stent graft alone by mounting it on a bare metal stent as a stent graft carrier.
