title: Purulent pericardial effusion and mycotic pseudoaneurysm following insertion of a bare metal stent.
abstract: A 65-year-old male was diagnosed with purulent pericarditis, caused by Staphylococcus aureus five weeks after bare metal stenting for a 90% stenosis of the right coronary artery ostium. Subsequently, he developed a pseudoaneurysm in the right coronary sinus of Valsalva (CSV) requiring surgical intervention during the treatment of the pericarditis. Bacteremia after percutaneous coronary intervention (PCI) occurs in < 1% of patients and usually has insignificant clinical sequelae. We present an infected coronary bare metal stent of the proximal right coronary artery after PCI that resulted in a purulent pericardial effusion and mycotic pseudoaneurysm of the right coronary sinus of Valsalva (CSV). The patient successfully underwent surgical treatment.
