Coronary stent infection: Interesting cases with varied presentation

Charan Reddy K V et al. J Cardiol Cases. .

Abstract

Stent infection after drug-eluting stent implantation is uncommon but is a critical event. In this study, we describe two such cases of coronary stent infection but with varied presentation. The first patient presented with recurrent stent thrombosis and acute coronary syndrome while the second patient was erroneously diagnosed as having tubercular pericarditis and was started on anti-tubercular therapy. Due to their possible fatal outcome, we herein report our experience with this uncommon clinical entity to help in rapid diagnosis and treatment. <Learning objective: Infection involving implanted stents is rare, it can, however, occur with high morbidity and mortality. In absence of diagnostic criteria or classic signs and symptoms, one should be aware of its presence and risk factors associated with it. Certain rare conditions such as JAK2 V617F mutation significantly alter hemogram leading to changes in red blood cell, white blood cell, and platelet counts facilitating coronary thrombosis should also be kept in mind.>.

Keywords: Coronary angiography; Coronary stent infection; JAC2 V617F mutation; Percutaneous coronary intervention.
