Surgical treatment of active native mitral infective endocarditis: A meta-analysis of current evidence

The native mitral lesion of active infective endocarditis implies a poor prognosis and is associated with adverse short- or long-term results without surgical treatment. Both mitral valvuloplasty (MVP) and mitral valve replacement (MVR) have been performed in the treatment of active native mitral infective endocarditis (ANMIE). However, the outcomes of the two approaches remain unclear. The aim of this study was to systematically review the two procedures with mortality and survival as the primary endpoints.
