Diphtheroid endocarditis after aortic valve replacement.

Diphtheroid endocarditis after aortic valve replacement was cured with penicillin, gentamycin and erythromycin. Infections occur most commonly on the aortic valves of men patients within two weeks after prosthetic insertion. Management with combined drug therapy based on sensitivities and clinical response are suggested. Paravalvular leaks do not necessarily require valve replacement.
