Mitral stenosis after mitral repair with using an annuloplasty ring is not common and it is almost always due to pannus formation. Mitral valve replacement was required in most of the previous cases of pannus covering the mitral valve leaflet, which could not be stripped off without damaging the valve leaflets. In two cases, we removed the previous annuloplasty ring and pannus without leaflet injury, and we successfully repaired the mitral valve. During the follow-up of 4 months and 39 months respectively, we observed improvement of the patients' symptoms and good valvular function. Redo mitral repair may be a possible method for treating mitral stenosis due to pannus formation after ring annuloplasty.
二尖瓣修复术后合并瓣环成形环导致的二尖瓣狭窄并不常见，几乎总是由于赘生物形成所致。大多数先前覆盖二尖瓣瓣叶的赘生物的病例都需要进行二尖瓣置换，而这些赘生物在不损伤瓣叶的情况下是无法剥离的。在两例病例中，我们在不损伤瓣叶的情况下移除了先前的瓣环成形环和赘生物，并成功修复了二尖瓣。分别随访 4 个月和 39 个月后，我们观察到患者症状改善和瓣膜功能良好。再次二尖瓣修复可能是治疗瓣环成形术后因赘生物形成导致的二尖瓣狭窄的一种可行方法。
