A 43 year old male underwent successful Percutaneous Coronary Intervention (PCI) to LCX. 3 months after the procedure, he presented with NYHA class III-IV angina associated with low grade fever and reduced appetite. Biochemical parameters including complete blood count and renal function tests were normal. ECG showed ST segment depression in lateral leads. Echocardiography showed lateral wall hypokinesia with moderate Mitral valve regurgitation. Coronary angiogram revealed large mycotic aneurysms in LAD and LCX coronary arteries (Image 1). Blood culture showed growth of Pseudomonas aeruginosa. Infected coronary aneurysms are a rare and potentially fatal complication after drug eluting stent implantationand may arise from contamination of cathlab equipment.
