Concurrent Pacemaker Lead Perforation and Subacute Coronary Stent Thrombosis: A Case Report.

Abstract

Stent thrombosis and lead perforation are important differentials for patients presenting with chest pain following recent coronary stent insertion and pacemaker insertion. In this report, we describe an unusual case of a 78-year-old male who presented with sharp chest pain one week after admission for posterior ST-elevation myocardial infarction (STEMI) and subsequent Mobitz type II block, for which he received primary percutaneous coronary intervention (PPCI) to the left circumflex artery (LCx) and dual chamber permanent pacemaker (PPM) insertion. Computed tomography (CT) chest and CT coronary angiogram (CTCA), respectively, showed he had concurrent lead perforation andstent thrombosis. On balance, the cause of chest pain was likely lead perforation. This diagnosis was reached by having a high index of suspicion for both of these important post-procedure complications and investigating appropriately.
