Mycotic aneurysm of the left ventricular free wall complicating aortic valve endocarditis

We report the case of a 34-year-old man with aortic valve infective endocarditis caused by methicillin-resistant Staphylococcus aureus, complicated by an aortic annular abscess. A 23-mm St. Jude HP aortic mechanical prosthesis was implanted. The pre-discharge transthoracic echocardiogram revealed a...
