Case Report: Coronary artery stent infection with mycotic aneurysm secondary to tricuspid valve infective endocarditis [version 1; peer review: 2 approved]

Abstract

Coronary artery stent infection with mycotic aneurysm is a rare life-threatening complication following coronary angioplasty, usually requiring surgical intervention. Reaching and confirming the diagnosis remains the most challenging aspect of this complication. We describe an unusual case of bare metal stent infection and coronary artery aneurysm in the setting of tricuspid valve infective endocarditis, resulting in ST elevation myocardial infarction, with a favorable outcome after primary angioplasty and antibiotic therapy. In the current era of growth of coronary stent implantation, it’s important for clinicians to consider and to prevent such potentially fatal events. The diagnosis process remains difficult and requires the association of multiple clinical, biological and imaging parameters. Although treatment modalities tend to favor surgery, we showed that coronary angioplasty could be a successful alternative solution.
