| 目的：观察和比较全软成形环与缘对缘瓣膜成形术在心脏瓣膜关闭不全成形术中的疗效。方法：回顾性研究我院行心脏瓣
膜关闭不全成形术患者80 例，随机分为Ⅰ组与Ⅱ组，每组各40 例。第Ⅰ组患者在行心脏瓣膜关闭不全成形术中使用全软成形环
进行治疗，第Ⅱ组患者在手术过程进行缘对缘瓣膜成形术。比较治疗前后两组患者二尖瓣口、二尖瓣环面积和收缩期及舒张期二
尖瓣环周径、左心室内径、心搏出量、射血速率、射血时间及临床有效率。结果：治疗后，两组二尖瓣形态、左心室内经、心搏出量、
射血速率及射血时间均较治疗前有所改善(P＜0.05)；且与第Ⅱ组相比，第Ⅰ组患者二尖瓣口面积、心搏出量及射血速率较大，二
尖瓣环的面积、收缩期及舒张期二尖瓣环周径、左心室内径较小，射血时间明显缩短(P＜0.05)。第Ⅱ组治疗总有效率为95%，较第
Ⅰ组(62.5%)显著升高，差异具有统计学意义(P＜0.05)。结论：与缘对缘瓣膜成形术相比，全软成形环在心脏瓣膜关闭不全成形术
中的疗效更好，其机制可能与增大二尖瓣口面积、心搏出量及射血速率，减小二尖瓣环的面积、收缩期及舒张期二尖瓣环周径、左
心室内径，缩短射血时间有关。 |

| Objective:To observe and compare the effect of Fully Flexible prosthetic Ring and edge to edge valvuloplasty in the
treatment of cardiac valve closure insufficiency.Methods:80 cases of patients with cardiac valve closure insufficiency from our hospital
were selected and randomly divided into the group Ⅰ and the group Ⅱ with 40 cases in each group. The groupⅠ was treated by fully
flexible prosthetic ring in cardiac valve closure insufficiency and the group Ⅱ was treated by edge to edge valvuloplasty. The mitral
stenosis, mitral annular area and mitral systolic and diastolic circumferential diameter, left ventricular diameter stroke volume, ejection
rate and radiation time blood and clinical efficiency were compared before and after treatment by SPSS19.0.Results:Compared with before
treatment, the mitral valve shape, left ventricle, stroke volume, ejection rate and ejection time in both groups were significantly improved
(P<0.05). Compared with group Ⅱ, the mitral valve orifice area stroke volume and ejection rate were higher in the group I, and
the mitral annular area, systolic and diastolic mitral annulus diameter, left ventricular diameter smaller and shoot blood time were significantly
shorter (P<0.05). The total effective rate was 95%in the group Ⅱ, which was higher than 62.5%in the group I, and the difference
was statistically significant (P<0.05).Conclusion:Compared with the edge to edge valvuloplasty, fully flexible prosthetic ring had better
efficacy in the treatment of cardiac valvular insufficiency, the mechanismmight be related to the increase of the mitral valve orifice area,
stroke volume and ejection rate, the decrease of mitral annular area, systolic and diastolic mitral annulus diameter, left ventricular diameter
and the shorten of ejection time. |
