Coronary drug-eluting stent infection complicated by coronary artery aneurysm and purulent pericarditis: complete resolution without surgery

Abstract Coronary stent infection is considered to be a rare but catastrophic complication of percutaneous coronary intervention. In this report, we present a 72-year-old man who developed a coronary stent infection complicated by coronary aneurysm and purulent pericarditis. Coronary artery aneurysm resolved over a period of 8 months following the successful management of infection with intensive antibiotic therapy alone. This case suggests that conservative therapy can be one of the therapeutic options in patients with high operative risks.
