    Abstract:

    Eustachian valve endocarditis (EVE) is a distinctly rare and underdiagnosed entity. We report 2 new cases caused by vancomycin resistant Staphylococcus aureus and Staphylococcus hominis diagnosed on transesophageal echocardiography (TEE). Although, 63% of Eustachian valve endocarditis is caused by Staphylococcus aureus, we report the first case of vancomycin resistant Staphylococcus aureus and first case related to implantable venous access systems. EVE is now seen more commonly in elderly population with diverse microbial cultures and antibiotic sensitivities. TTE is the first modality for investigation of EVE, however a negative TTE does not preclude the diagnosis, as only 88% of cases were diagnosed on TEE.

    Key words: Echocardiography, endocarditis, Eustachian valve, transesophageal, vancomycin.
