Successful long-term antibiotic suppressive therapy in a case of prosthetic valve endocarditis and a case of extensive aortic and subclavian graft infection.

The indication for surgical valve replacement in cases of infective endocarditis is well defined in current guidelines. However, some patients are not fit or willing to undergo major surgical procedures. Interestingly, to the best of our knowledge, there is scarce information in the literature on how to deal with such cases and what might be the outcome. We present two complicated cases of prosthetic infective endocarditis with definite indication for replacement of involved foreign material, who were treated successfully with long-term suppressive antibiotic therapy. These two cases demonstrate that individualized long-term antibiotic suppressive therapy might be effective in selected patients with complicated PVE unfit or unwilling to undergo high-risk cardiothoracic surgical interventions.
