Grade III Coronary Artery Perforation Following PCI and Unusual Stent Graft Delivery System

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