施行二尖瓣置换 mitral valve relplacement ; MVR
结果全组无手术死亡病例，2例行二尖瓣置换术。
Results The group had no case dead, 2 cases need re-mitral valve replacement.
心尖部闻及收缩期杂音13例，再次行二尖瓣置换术3例；
Mitral systolic murmur was documented in 13 cases with reoperative valve replacement performed in 3 patients.
结论二尖瓣成形术治疗小儿先天性二尖瓣反流近期效果理想，能适应患儿的生长，可以有效地延迟或避免行二尖瓣置换术。
Conclusion mitral valvuloplasty in children may lead to favorable early outcomes, adapt to children's growth, and effectively delay or avoid mitral valve replacement.
