Standardized Subannular Repair for Type IIIb Functional Mitral Regurgitation in a Minimally Invasive Mitral Valve Surgery Setting

In this study, the authors report on the outcome of mitral valve repair, applying subannular repair for functional mitral valve regurgitation. Included are 108 patients who underwent annuloplasty with subannular repair (n=60) versus patients with annuloplasty only (n=48). Repositioning of the papillary muscle lead to excellent outcomes with less mitral valve regurgitation recurrence.
