Coronary stent infections (CSI) are rare but a potentially life-threatening disease, the incidence of which has been on a rise over the last two decades. We report the case of a patient who presented with episodes of fever and discharging sternal wound. The patient was diagnosed as CSI arising from the left anterior descending artery stent which was communicating anteriorly to the skin and posteriorly as lobar-fistula. He was treated by stent removal and plication of the fistula. Blood culture, culture of the pus and infected stent, and coronary angiography are the preferred diagnostic modalities, followed by positron emission tomography (PET) scan and cardiac magnetic resonance imaging (MRI) for delineating the extent of pathology. Surgery seems to be the treatment of choice, providing a definitive diagnosis of CSI and removing the source of infection, repairing aneurysms, and providing bypass vascular grafts if feasible. Thorough evaluation and a multidisciplinary approach with the institution of appropriate medical and surgical therapy lead to timely detection and good outcome.
