Abstract:
Perforation of a left internal mammary artery (LIMA) graft during percutaneous coronary intervention is a rare event. We report a case of mid-LIMA perforation treated by a polytetrafluoroethylene-covered stent using a modification of the dual catheter ("ping pong") technique. We propose that use of this modification when possible will further improve safety of treating a perforation.
