objective: A new mitral valuloplasty technique involving a special annuloplasty strip (Mitralift®) was performed for the past 6 years. Recently, the procedure was applied to patients with mitral stenosis as well as mitral regurgitation. This study is aimed to assess the efficacy of this new mitral valvuloplasty consisting of a lifting mitral annuloplasty (LMA) with posterior and/or anterior leaflet extension (PLE/ALE) to increase the coaptation surface.
Methods: The medical records of 413 patients (249 females and 164 males) who underwent a new mitral valvuloplasty from Mar 2008 to Feb 2010 were retrospectively reviewed. The mean age was 52±15 years. LMA is a new mitral annuloplasty method which involves lifting up of the downwardly displaced LV wall by applying specially designing fabric annuloplasty strip (Mitralift®) on the left atrial wall along the posterior mitral annulus.PLE/ALE was applied to the patients who had contracted mitral leaflet by utilizing a patch of bovine pericardium tailored over a template (SC template®) according to the size of the annuloplasty strip. The patients were divided into two groups; MR group (n=245) and MS group (n=168).
Results: There were six early deaths (1.5%) and two follows up death (0.5%). Reoperations were performed for recurrent infective endocarditis in 1 case and recurrent MR in 2 cases. The mean MR grade was decreased from 3.0±0.8 to 0.2±0.6 (p<0.05) in MR group. Mean effective mitral orifice area was increased from 1.2±0.3 cm2 to 1.9±0.6 cm2 (p<0.05) in MS group.
Conclusions: The early outcome of the described new mitral valvuloplasty shows favorable early results for various types of mitral valve disease
