Transcatheter retrieval of device entrapment: management of a rare complication of percutaneous coronary intervention: case report and literature review.

With the continued advancement in PCI equipment and techniques, complications arising from intracoronary manipulation are encountered. Such complications are associated with major adverse outcome including death; myocardial infarction (MI) and the need for urgent coronary artery bypass surgery (CABG), and they require prompt recognition and mediation by the interventional cardiologist. We report a case of a broken stent shaft system in the setting of acute coronary syndrome and its successful retrieval using a non-compliant balloon to trap the proximal portion of the shaft within the guide ("trapping" a procedure used in coronary Chronic Total Occlusions (CTO) interventions) followed by slow withdrawal of the whole system. This was followed by successful PCI of the culprit lesion using a drug eluting stent without any residual complications.
