Key result
Mitral valve repair with PTFE suture neochordae and ring annuloplasty resulted in 97% survival, 87.9% freedom from ≥+2 recurrent mitral regurgitation, and a 6.1% reoperation rate at 15.3 months.

Does mitral valve repair with PTFE suture neochordae and ring annuloplasty provide satisfactory medium-term outcomes in patients with Carpentier class II mitral valve prolapse?
Mitral valve repair using PTFE suture neochordae and ring annuloplasty for Carpentier class II mitral valve prolapse provides satisfactory medium-term survival and freedom from recurrent mitral regurgitation.
Supports mid-term neochordae repair durability in prolapse; leaves open need for RCTs versus alternatives.
Objective: Mid-term results of mitral valve repair with polytetrafluoroethylene (PTFE) suture neochordae and ring annuloplasty on patients with Carpentier functional class II mitral valve prolapse caused by rupture or elongation of chordae were investigated.Methods: 33 patients underwent repair of mitral regurgitation (MR) due to mitral leaflet prolapse between 2009 and 2012, were evaluated. Cross-sectional study was performed in two stages. All of the patients included in the study had Carpentier type II MY caused by excessive leaflet motion (elongation or rupture of chordae). At medium term follow-up, the ratio of riddance from recurrent mitral insufficiency, survival and reoperation were evaluated.Results: There was no hospital mortality. Medium-term (15.3 ± 8.1 months) survival was 97% (32/33 patients). At follow-up, while 6 (18.8%) patients had trivial (+1) MR, 2 (6.1%) patients had mild (+2) MR, 2 (6.1%) patients had moderate (+3) MR and no patients had severe (+4 ) MR. Freedom from +2 recurrent MR was 87.9% (29/33 patients). The application rate of reoperation was 6.1% (2/33 patients). Two patients underwent reoperative mitral valve replacement because of the development of mitral repair failure in 1 patient and moderate (+3) MR in 1 patient within 2 month.Conclusion: Repair of mitral leaflet with PTFE suture neochordae in mitral valve prolapse due to pathologies of chordae rupture or elongation may be preferred as an alternative with satisfactory mid-term results.

Kara et al. (2014) conducted a cross-sectional in Mitral valve prolapse (Carpentier functional class II) (n=33). Mitral valve repair with PTFE suture neochordae and ring annuloplasty was evaluated on Freedom from ≥+2 recurrent mitral regurgitation at medium-term follow-up. Mitral valve repair with PTFE suture neochordae and ring annuloplasty resulted in 97% survival, 87.9% freedom from ≥+2 recurrent mitral regurgitation, and a 6.1% reoperation rate at 15.3 months.
