[Surgical treatment for mitral valve prolapse]
1Department of Thoracic and Cardiovascular Surgery, Second Affiliated Hospital, Hunan Medical University, Changsha 410011.
Objective:
To determine the excellent operative procedure to treat mitral valve prolapse (MVP).
Methods:
Fifty seven patients with MVP were divided into three groups: Group I received traditional chordal reconstruction; Group II underwent chordal replacement using expanded polytetrafluorethylene(e-PTFE) sutures and artificial ring valvuloplasty reconstruction; Group III submitted mitral valve replacement.
Results:
Mitral regurgitation volume was reduced significantly in Group II [(1.3 +/- 3.8) ml] and Group III [(1.2 +/- 3.4) ml] than that in Group I [(4.7 +/- 7.7) ml] (P < 0.05).
Conclusion:
The utilization of e-PTFE sutures as artificial chordae and artificial ring valvuloplasty for MVP is a more reliable and safe procedure than traditional mitral valve reconstruction, and can avoid the complications of long term anticoagulant therapy after mechanical valve replacement.
