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.

Abstract Background We report the case of minimally invasive mitral valve repair in an 86-year-old female with symptomatic structural mitral regurgitation and severe pectus excavatum. Case Description The case summarizes four areas of repetitive heart team discussions. First, should an 86-year-old patient still be treated invasively? Second, if so, should treatment be interventional or surgical? Third, if surgical, should we replace or repair at that age and fourth which surgical access is best with respect to her chest deformation? Conclusion We chose to surgically repair the valve using a minimally invasive approach. The patient was extubated 3 hours after surgery and discharged after 7 days.

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.

Repair Techniques

Mitral valve regurgitation may require complex repair techniques that are challenging in minimally invasive and may expose patients to prolonged cardiopulmonary bypass and cross-clamp times. Here, we present a stepwise operative approach that may facilitate the repair of the mitral valve in a minimally invasive fashion and may be carried out even when multiple posterior segments are involved. This how-to-do article presents a method that was performed in 148 patients that were referred to our institution for severe organic mitral regurgitation between 2008 and 2016. At mean ± SD follow-up of 45.5 ± 27 months, freedom from recurrent of mitral regurgitation 2+ or greater and reoperation was 95.2%.

New Energy

Advances in surgery for atrial fibrillation from cut and sew technique to thoracoscopy and new energy source have enabled minimally invasive approach which avoids median sternotomy and cardiopulmonary bypass. However, minimally invasive approach is unable to match the outcome of classic surgical technique due to difficulty in creating some of linear ablation lines. Hybrid procedure using catheter mapping and ablation in addition to minimally invasive surgical ablation has gained interest to combine the advantages of both procedures. No large study has been conducted to date comparing this new technique to other existing treatments. The aim of this paper is to review the data on hybrid procedure for atrial fibrillation and assess its early outcome and efficacy.

Ventricular Dyssynchrony

Mitral regurgitation in dilated cardiomyopathy is usually considered “functional,” and many such patients are treated medically. Surgery is often offered as a last resort in select patients who have failed medical therapy. We report a patient with dilated cardiomyopathy with ventricular tachycardia and ventricular dyssynchrony and “structural mitral regurgitation” due to chordal tethering, which was managed surgically using a minimally invasive approach.

Bioprosthetic Mitral Valve

A 90-year-old woman with two previous mitral valve replacements, presented with pulmonary edema due to mitral regurgitation from degeneration of her bioprosthetic mitral valve. A minimally invasive approach was used to replace the bioprosthetic mitral valve. During surgery, the bioprosthetic valve was noted to be too adherent to the endocardium of the left atrium, making removal of the prosthesis not only difficult, but also potentially harmful. The new bioprosthetic valve was instead placed using a valve-in-valve approach.
