“…However, since the artificial chordae technique does not require resection of the valve leaflet, the repaired leaflet is expected to maintain its flexibility and a large mitral valve area. The report of Takai, et al supports this theory [15]. Future studies should be performed to confirm the superiority of artificial chordae.…”

Background: Recently, the concept of "Respect rather than resect" has been proposed in an attempt to restore mitral valve function. We investigated the results of mitral valve repair for posterior leaflet disease. Methods: Between April 2008 and July 2017, mitral valve repair was performed in 78 cases at our facility. Among them, 37 cases were analyzed. We divided patients into three groups according to the repair techniques used: artificial chordae technique, which uses the anchoring-technique and measured tube technique (Group A, 23 cases), resection and suture technique (Group R, 10 cases), and artificial chordae together with resection and suture technique (Group AR, 4 cases), and compared their postoperative outcomes. Results: Residual postoperative mitral regurgitation (MR) grade in groups A, R and AR at discharge were 0.3 ± 0.4, 0.8 ± 0.9 and 0.0 ± 0.0 (p = 0.07), respectively. Mitral valve areas (cm 2) in groups A, R and AR were 3.2 ± 0.6, 2.9 ± 0.6 and 3.0 ± 0.6 (p = 0.47), respectively. Freedom from severe MR at 5 years postoperatively was seen in 91.7%, 90% and 100% (p = 0.92) in groups A, R and AR, respectively. Conclusions: There was no significant difference in postoperative outcomes, as assessed echocardiographically, between the artificial chordae technique and resection and suture technique. The results of all repair techniques were satisfactory.

“…The early and mid-term outcomes of MVP with our modified method are satisfactory in our institute, and these are comparable to those reported in literature. [ 26 27 28 ] Therefore, we concluded that our modified technique was a simple, safe, and effective for correcting severe MR associate with mitral valve prolapse.…”

Background:Right minithoracotomy (RM) has been proven to be a safe and effective approach for mitral valve surgery, but the differences of artificial chordae technique between RM and median sternotomy (MS) were seldom reported. Here, we compared the outcomes of modified artificial chordae technique for mitral regurgitation (MR) through RM or MS approaches.Methods:One hundred and eighteen consecutive adult patients who received mitral valve repair with artificial chordae and annuloplasty for MR through RM (n = 58) or MS (n = 60) from January 2006 to January 2015 were analyzed.Results:All of the selected patients underwent mitral valve repair successfully without any complication during the surgery. There was no significant difference between RM group and MS group in cardiopulmonary bypass time, aortic cross-clamp time, and early postoperative complications. However, compared with the MS group, the RM group had shorter hospital stay and faster surgical recovery. At a mean follow-up of 44.8 ± 25.0 months, the freedom from more than moderate MR was 93.9% ± 3.5% in RM group and 94.8% ± 2.9% in MS group at 3 years postoperatively. Log-rank test showed that there was no significant difference in the freedom from recurrent significant MR between the two groups (χ2 = 0.247, P = 0.619). Multivariate analysis revealed that the presence of mild MR at discharge was the independent risk factor for the recurrent significant MR.Conclusion:Right minithoracotomy can achieve the similar therapeutic effects with MS for the patients who received modified artificial chordae technique for treating MR.
