“…Since some patients present with recurrent MR following restrictive annuloplasty, particularly in case of advanced LV remodelling or extensive regional remodelling in the infero-basal segments [15], current research has been devoted towards adjunctive procedures at the LV level and randomised trials comparing repair versus replacement for ischaemic MR are ongoing. In analogy, intraventricular procedures which do not fix the anteroposterior mitral diameter, which has been shown to be a major determinant of the annulo-papillary distance and, consequently, of functional MR [19], might not prove durable in case of advanced cardiomyopathy.…”

Despite advanced cardiomyopathy, SVR determines left ventricular volume reduction and improved systolic function. Baseline absent-to-moderate mitral regurgitation and a more spherical left ventricular geometry predict a less favourable clinical and functional outcome, suggesting a possible rationale for wider indications for combined correction of 2+ mitral regurgitation and undersizing of the mitral annulus, particularly in patients with sphericity index > or =0.75.

Secondary mitral regurgitation (MR) is present in up to half of patients with dilated cardiomyopathy, and is associated with a poor prognosis. It primarily results from progressive left ventricular remodelling, papillary muscle displacement and tethering of the mitral valve leaflets. Mitral valve repair with an undersized ring annuloplasty is the reparative procedure of choice in the treatment of secondary MR. However, this technique is associated with a 30-60% incidence of recurrent moderate or greater MR at mid-term follow-up, which results in progressive deterioration of left ventricular function and increased morbidity. Combined mitral valve repair and papillary muscle approximation has been applied in order to address both the annular and subvalvular dysfunction that coexist in secondary MR, which include graft and suture-based techniques. Herein, we provide a systematic review of the published literature regarding the technical aspects, clinical application, and outcomes of mitral valve repair with combined ring annuloplasty and papillary muscle approximation for the treatment of secondary MR.
