Juxta-annular right atrial anchoring of prosthetic mitral valves in endocarditis with anterior annulus destruction†

Destruction of the mitral annulus is associated with poor outcomes. We present the treatment of endocarditis using a technique that enables secure anchoring of prosthetic valves where the anterior part of the mitral annulus is severely disrupted. It was used in 5 patients. Follow-up at 10 ± 4 months showed the valves intact without recurrence of endocarditis. Mortality was limited to 1 patient who died of non-cardiac causes. We conclude that partial right atrial anchoring is a useful bail-out and enables favourable outcomes in patients with extensive loss of the (peri)annular tissue due to endocarditis.
