Abstract

Background: The mitral valve repair with artificial chordae has been used since 1960. Because of the invention of Gore – Tex suture, this method has become more complete with a lot of advantages such as: tissue reconstruction instead of resection, preserving either the connection of mitral valve complex or coaptation. In Hanoi Heart Hospital, we have made use of this method reccently in patients with mitral regurgitation. The objective of this research are analysing the characteristics and evaluating the result of mitral valve repair with artificial chordae in Hanoi Heart Hospital. Methods: A cross – sectional study. We retrospectively reviewed 42 patients undergoing mitral valve repair with artificial chordae in Hanoi Heart Hospital from 1/2017 to 4/2021. Data processing using SPSS 22 software. Results: The anterior leaflet prolapse counted for 61.9 %, the posterior leaflet prolapse counted for 21.4 % and the rest was combination. The main cause was degenerative mitral regurgitation (90.5%). 28.6% patients had the minimally invasive cardiac surgery. The loop technique could be seen in 24 patients (57.1%), the mitral repair with PTFE neochordae was used in 18 cases (42.9%). No death was identified. The percentage of patients with no residual regurgitation in the follow – up of 1 month, 3 months, 1 year, 2 years, 3 years was 97.6%, 97.6%, 92.9%, 92.9% and 83.3% respectively. Conclusion: The early and middle-term outcomes of mitral valve repair with artificial chordae were good.
