Infective endocarditis with myocardial abscesses complicating percutaneous transluminal coronary angioplasty.
A 73-year-old man who had undergone percutaneous transluminal coronary angioplasty developed infectious endocarditis caused by Staphylococcus aureus. Echocardiography revealed vegetations of the aortic valve and severe aortic regurgitation. Endotracheal intubation was required for progressive heart failure. Serum creatinine kinase was elevated (411 IU/l: normal 30 to 140 IU/l). Electrocardiography showed no ischemic changes. Aortic replacement was performed to treat progressive heart failure, but the patient could not be weaned off cardiopulmonary bypass and subsequently died. A post-mortem examination revealed multiple myocardial microabscesses and myocardial infarction due to embolic vegetation. The possibility of multiple abscess formation when severe ventricle dysfunction occurs in infectious endocarditis is emphasized.
