Infectious complications of coronary angioplasty and stenting are uncommon. A 70-year-old man is presented who underwent percutaneous transluminal coronary angioplasty (PTCA) and stenting of an occluded left anterior descending artery. This was complicated by Staphylococcus aureus pericarditis with tamponade. He was successfully treated with a closed drainage and antibiotics. This is the first reported case in the literature that documents purulent pericarditis and tamponade following percutaneous revascularization.
