Mitral valve repair with an annuloplasty ring for mitral valve regurgitation in children and the short-term follow up

Objective Mitral valve regurgitation often leads to cardiac insufficiency or even heart failure. Methods We tried a mitral valve annuloplasty with a ring to improve the effect of mitral valvuloplasty, 5 males and 6 females; aged(8.0±4.5)years; weight(26.1±13.9)kg. From February 2015 to December 2017, 11 children underwent mitral valve annuloplasty with an mitral valve ring in our hospital. Immediately after surgery, the degree of mitral valve regurgitation was significant improved from moderate-severe to mild-moderate(P<0.05). Results 1 case of early death, 1 case had a mitral valve replacement because of early hemolysis. The rest of the children were discharged smoothly. The follow-up of 3 months of mitral valve regurgitation was not aggravated comparing with that immediately after surgery(P>0.05). There was no worsening of cardiac function at follow-up(P>0.05), and no other adverse events. Therefore, artificial mitral annuloplasty with a ring is effective in treating mitral regurgitation in children. The annulus had potential growth characteristics and did not require lifelong oral anticoagulant. Conclusion For some patients with difficulty, this method of mitral valvuloplasty can enlarge the surgical indication and improve the quality of life of children. The treatment effect is good.
