“…Matsui et al 27 described a modified version of the papillary muscle sling, using pledgeted sutures to pull the papillary muscles together. Ishikawa et al 28 introduced the “sandwich plasty,” which brings together the heads of each papillary muscle. This brings the chordae to the anterior and posterior leaflet together, facilitating coaptation.…”

Background and Aim of the Study The aim of this meta‐analysis was to compare short‐ and long‐term outcomes of patients undergoing mitral annuloplasty (MA) with or without papillary muscle surgery (PMS) for the treatment of ischemic mitral regurgitation (IMR). Methods A systematic review and meta‐analysis in accordance with the Preferred Reporting Items for Systematic Reviews and Meta‐Analyses (PRISMA) statement were performed. Results Nine studies met the inclusion criteria. This meta‐analysis identified 478 patients: 228 patients underwent MA alone and 250 patients underwent concomitant PMS. Early mortality was similar between two groups (odds ratio [OR] 1.14, 95% confidence interval [CI], 0.51‐2.53; P = .75). PMS was associated at follow‐up with a higher freedom from cardiac‐related events (P = .050); moreover, although both surgical techniques had a positive impact on ventricular remodeling, the PMS group showed a significant higher reduction of left ventricle end‐diastolic diameter (OR, 4.89, 95% CI, 2.77‐7.01; P < .001) and left ventricle end‐systolic diameter values (OR, 4.11, 95% CI, 1.98‐6.24; P < .001). Finally, PMS compared with MA alone was associated with a significant reduction of recurrent mitral regurgitation at follow‐up (OR, 3.25, 95% CI, 1.60‐6.59; P = .001). Conclusions This meta‐analysis demonstrated superiority in terms of ventricular remodeling of a combined approach encompassing PMS and MA over MA alone in IMR. Moreover, the association of subvalvular surgery with restrictive MA decreases the incidence of mitral regurgitation recurrence and cardiac‐related events at follow‐up.

SummaryWe initiated an original papillary muscle head approximation procedure, commonly known as Sandwich plasty, for the treatment of ischemic mitral regurgitation (MR). In this study, we evaluated the appropriateness of this procedure for functional MR associated with aortic valve disease. Fifteen patients who had undergone Sandwich plasty combined with aortic valve surgery were included in this study. The mean age of the patients was 69 years. Predominant aortic valve diseases were regurgitation in 8 patients and stenosis in 7 patients. Aortic valve replacement was performed in 14 patients and David surgery in one. The mitral valve was approached through the aortic annulus in 9 patients (the transaortic group). Six other patients with mitral valve annulus of 30 mm or larger underwent concomitant mitral ring-annuloplasty through a left atrial incision (the LA group). The tenting height of the mitral valve and left ventricle diastolic diameter significantly decreased after surgery in both groups. After surgery, residual moderate or mild MR was detected in two patients in the transaortic group. In the LA group, residual mitral regurgitation was not detected. In the follow-up study, prominent MR occurred in two patients in the transaortic group. The MR free rate two years after surgery was 83% in the total patient population. Sandwich plasty was simple and effective in the treatment of functional mitral regurgitation combined with aortic valve surgery. A transaortic approach is effective in obviating a separate left atriotomy and reducing operation time. (Int Heart J 2010; 51: 47-50)
