title: Mitral valve re-repair in an adolescent patient with prosthetic ring endocarditis: posterior leaflet augmentation and posterior strip annuloplasty.
abstract: Endocarditis after mitral valve (MV) annuloplasty is uncommon. The ring used in MV annuloplasty is often inadequate because it opposes the growth of the MV leaflets and annulus. We report a 15-year-old male that required redo surgery for prosthetic ring endocarditis 40 months after a previous MV annuloplasty. After the previous ring was removed, the undergrown posterior leaflet was repaired with pericardial augmentation and the posterior annulus was stabilized with a Mitra-Lift® supra-annular strip to preserve a flexible valve orifice and allow the anterior MV annulus and the commissures to grow in relation to body size.
