Abstract

From 2015 to 2018, 27 patients underwent mitral valve repair by the technique of applying artifitial chordae in the Heart Institute of Ho Chi Minh, Vietnam. Valve disease was degenerative in most cases. No death after 2 years of follow-up overall. Freedom from re-operation at 2 years was 96.3% ( 1 case of re-operation related to cardiac insufficiency. The grades of mitral regurgitation at 2 years were 96.3% absent or mild, 3.7% moderate. ). Good heart function after the repair, EF 58.22% at 1 month, and 61.3% at 3 months and stable after that; sinus rhythm by 2-year follow-up ( with 14.8% Maze procedure applied). Ring used for most of cases after the valve repair, from size of 28 to 36. This study showed strong benefits and excellent results of mitral valve repair by applying artifitial chordae at 2-year follow-up, confirming reliablility and durability of this technique for the patients. This showed a good solution for mitral regurgitation by safe technique, and increase feasibility of mitral valve repair
