[Pseudoaneurysm with Infective Endocarditis Ten Years After the Resection of Pseudoaneurysm Complicated with Myocardial Infarction;Report of a Case].

A 76-year-old female was referred to our hospital for fever and chillness. She was diagnosed with pneumonia and sepsis, and methicillin-resistant Staphylococcus aureus (MRSA)was detected by the sputum culture. Echocardiography showed mobile vegetation and left ventricular pseudoaneurysm at the apex. As she had a history of ventricular pseudoaneurysmectomy 10 years before, we considered the patient had developed infective endocarditis at the surgical site. Surgical treatment was needed because of the rapidly growing pseudoaneurysm despite the use of antibacterial agents. She successfully underwent resection of the pseudoaneurysm and MRSA was also detected in the culture of the previous vascular graft patch. Antibacterial agents were administrated for 6 weeks, and she was discharged at 53 days after operation.
