A Case of Aortic Valve Endocarditis Complicated with an Aneurysm and Perforation of Anterior Mitral Leaflet

ABSTRACT

Aortic valve is usually involved in infective endocarditis. Aortic valve endocarditis produces destruction and perforation of leaflets and results in ring abscess, frequently. Less commonly, direct extension or infected aortic regurgitant jet can produce secondary involvement of anterior mitral leaflet (AML) and result in the formation of an aneurysm or perforation of AML. A 60-year-old woman was admitted to Kyung Hee University hospital because of a febrile illness and dyspnea. Transthoracic echocardiography (TTE) showed an aortic valve vegetation, an aneurysm of AML, and an eccentric jet of mitral regurgitation through AML. Transe-sophageal echocardiography (TEE) showed a perforation of AML. -streptococcus was isolated from blood culture. The patient was treated with Vancomycin and Sisomicin sulfate. On hospital day 21, heart failure was aggravated and emergent double valve replacement was done. The patient was recovered and discharged.
