Bartonella haenselae infective endocarditis following transcatheter edge-to-edge mitral valve repair: A case report.

Infective endocarditis following a Mitraclip procedure might be an under-recognized complication. We describe the case of infective endocarditis by Bartonella henselae as a late complication in a patient with a previously implanted MitraClip system for mitral valve repair. Due to the severity of infection, surgical treatment was performed despite the high preoperative surgical risk, but recurrence of endocarditis of the biological valve implanted occurred. Although infection with Bartonella is known as a possible source of endocarditis, it has never been described before in relation to failed MitraClip therapy.
