Percutaneous Coronary Intervention (PCI) is one of the most commonly performed lifesaving cardiac procedures. While its outcomes are generally excellent, rare complications can present significant diagnostic and therapeutic challenges. A remarkable case published in the European Heart Journal – Case Reports (ESC) describes the exceptionally rare "Vanishing Stent" phenomenon, caused by a mycotic coronary pseudoaneurysm following PCI.

The patient presented with recurrent ischemic symptoms after stent implantation. Advanced imaging with Optical Coherence Tomography (OCT) and ¹⁸F-FDG PET-CT revealed infective arteritis that had led to complete destruction of the previously implanted coronary stent and the formation of a coronary pseudoaneurysm. The patient was successfully managed using covered stent implantation, resulting in exclusion of the pseudoaneurysm and restoration of coronary…
