Abstract OBJECTIVES Subannular repair techniques in addition to undersized ring annuloplasty have been developed to address high mitral regurgitation (MR) recurrence rates after mitral valve repair in type IIIb MR. We compared the results of annuloplasty with simultaneous standardized subannular repair versus isolated annuloplasty, focusing on the periprocedural outcomes of minimally invasive procedures. METHODS A consecutive series of 108 patients with type IIIb functional MR with severe signs of bileaflet tethering underwent an annuloplasty + subannular repair (group A; n = 60) versus isolated annuloplasty (group B; n = 48). The primary end point of this prospective, parallel cohort study was death or recurrent MR >2, 1 year postoperatively. The secondary end points were survival and clinical outcomes, with special regard for the minimally invasively treated subgroups. RESULTS Duration of surgery, cardiopulmonary bypass time and aortic cross-clamp time were comparable between both study groups. Procedural outcomes as well as echocardiographic outcome parameters were similar and independent of access (fully endoscopic versus full sternotomy). At the 12-month follow-up, death or MR >2 occurred in 3.3% (2/60) of patients in group A vs in 20.8% (10/48) of patients in group B (P = 0.037). The overall mortality rate during the follow-up period was 1.7% (1/60) in group A vs 12.5% (6/48) in group B (P = 0.041). CONCLUSIONS Standardized realignment of papillary muscles is feasible and reproducible via a minimally invasive approach, resulting in excellent periprocedural outcomes, and has a clear potential to significantly decrease MR recurrence and improve 1-year outcomes compared to isolated annuloplasty.

Objective Pathophysiological background of type IIIb functional mitral regurgitation (FMR) is a progressively increasing distance between papillary muscle tips and mitral annular plane. Standard surgical treatment of such FMR by means of undersized mitral annuloplasty is associated with a high recurrence rate. Methods We propose a modified subannular maneuver to correct type IIIb FMR while combining undersized annuloplasty with a controlled realignment of both papillary muscles, thereby fixing the distance between mitral annular plane and papillary muscle tips. The differences of this subannular maneuver as compared with the previously published techniques are the following: (1) controlled realignment of both papillary muscles, (2) fixation of the papillary muscles to mitral annulus distance on an annuloplasty ring, and (3) application in a three-dimensional endoscopic minithoracotomy setting. Results We describe a surgical technique of minimally invasive mitral valve repair performed due to severe type IIIb FMR, which includes a modified subannular maneuver to realign both papillary muscles. Preliminary results of the first 10 patients who underwent this procedure at our institution are presented. There was no in-hospital mortality and follow-up echocardiography (mean ± SD echocardiographic follow-up = 10 ± 6 months) demonstrated stable functional results. Conclusions Our initial experience indicates that adding of this subannular maneuver to the standard annuloplasty and thereby fixing the distance between papillary muscles and mitral annular plane have a potential to improve results of surgical FMR treatment.

Transaortic Approach

<p><b>Objective:</b> We retrospectively evaluated the results of an edge-to-edge repair (Alfieri stitch) of the mitral valve performed via a transaortic approach in patients who were undergoing minimally invasive aortic valve replacement.</p><p><b>Methods:</b> From January 2010 to September 2010, 6 patients underwent minimally invasive edge-to-edge repair of the mitral valve via a transaortic approach with concomitant aortic valve replacement. The patients were considered to be candidates for this procedure if they were deemed by the surgeon to be high-risk for a double valve procedure and if on preoperative transesophageal echocardiogram the mitral regurgitation jet originated from the middle portion (A2/P2 segments) of the mitral valve.</p><p><b>Results:</b> There was no operative mortality. Mean cardiopulmonary bypass time was 137 minutes, and mean cross-clamp time was 111 minutes. There was a significant improvement in the mean mitral regurgitation grade, with a mean of 3.8 preoperatively and 0.8 postoperatively. The ejection fraction remained stable, with mean preoperative and postoperative ejection fractions of 43.3% and 47.5%, respectively. Follow-up transthoracic echocardiograms obtained at a mean of 33 days postoperatively (range, 8-108 days) showed no significant worsening of mitral regurgitation.</p><p><b>Conclusion:</b> Transaortic repair of the mitral valve is feasible in patients undergoing minimally invasive aortic valve replacement.</p>

Mitral Apparatus

In patients with functional mitral regurgitation, the placement of a sling encircling both papillary muscles in conjunction with mitral annuloplasty appears to be a rational approach for surgical correction, because it addresses both the mitral valve and the deformities of the subvalvular mitral apparatus. Reports in the literature that describe the utilization of this technique are few, and mainly involve a median sternotomy approach. The purpose of this communication is to describe the technical details of performing this procedure via a minimally invasive approach.
