In adult patients who have undergone mitral annuloplasty with a rigid ring at a young age, the mitral valve may ultimately deform and demonstrate insufficient growth because the valve annulus is fixed to the ring. Mitral valve re-repair, following this scenario, was performed for mitral stenoinsufficiency in a 26-year-old female patient who had undergone mitral annuloplasty with a rigid ring at the age of five years. The valve re-repair procedure consisted of decalcification and stripping of the anterior leaflet and annulus, posterior leaflet augmentation using an elliptical autologous pericardial patch, and a posterior strip annuloplasty sparing the anterior annulus and commissures. Using this procedure, the mitral valve recovered sufficient coaptation area for valve competence, and anterior annular motion was resumed with resultant dynamic changes of the septolateral annular dimension.
在年轻时接受过刚性环二尖瓣环成形术的成年患者中，二尖瓣可能最终会变形并显示生长不足，因为瓣环被固定在环上。在此种情况下，一名26岁女性患者因二尖瓣狭窄关闭不全接受了二尖瓣再次修复手术，该患者在5岁时接受过刚性环二尖瓣环成形术。瓣膜再次修复手术包括前叶和瓣环的脱钙和剥离、使用椭圆形自体心包补片扩大后叶以及保留前瓣环和瓣叶联合处的后瓣环条带成形术。通过该手术，二尖瓣恢复了足够的瓣叶对合面积以实现瓣膜功能，并且前瓣环运动得以恢复，导致间隔侧瓣环尺寸发生动态变化。
