[Nocardia endocarditis in aortic and tricuspid native valves].

Nocardia endocarditis in native valve is an uncommon infection that usually arises in immunodepressed patients. We report a 51-year-old man diagnosed as having Nocardia endocarditis in aortic and tricuspid native valves, which received antimicrobial therapy and required aortic valve replacement. In 6 month follow up the patient remained asymptomatic with good clinical evolution.
