Combined mitral and aortic homograft valve replacement for acute bacterial endocarditis.

Homograft replacement of the aortic valve in cases of acute bacterial endocarditis is considered the ideal choice because of the resistance of the homograft to reinfection. We report a case of aortic and mitral valve bacterial endocarditis, secondary to Streptococcus viridans, with severe aortic and mitral valve regurgitation and hemodynamic instability requiring surgical interventions with the use of aortic and mitral valve homografts.
