Emergency polytetrafluoroethylene-covered stent implantation to treat right coronary artery perforation during percutaneous coronary intervention

Abstract

Coronary artery perforations are life-threatening complications with a poor outcome. Historically, if the perforation was not controlled using conservative methods such as prolonged balloon inflation and protamine administration, emergency cardiac surgery has been performed. However, several percutaneous methods including covered stents and embolization materials have emerged as therapeutic options to manage coronary perforations. We report a case of right coronary artery perforation after high pressure stent post-dilatation that was successfully sealed with a polytetrafluoroethylene-covered stent.
