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.
