Large mural vegetation attached to the left ventricular outflow tract: a case report.

We describe an unusual case of staphylococcal endocarditis with vegetation attached to the left ventricular outflow endocardium in a patient with chronic severe aortic regurgitation that was diagnosed by transthoracic echocardiography. There was no involvement of aortic valve endocardium confirmed by transthoracic echocardiography, transesophageal echocardiography, and macroscopically in the operation. This report confirms that chronic endocardial trauma may provide a fertile nidus for the development of bacterial vegetation.
