后瓣

B组：在后瓣边缘矩形切除部分瓣叶5mm×10mm大小，用蝌蚪形新鲜自体心包片修补瓣叶缺损，心包条作为腱索缝合于右心室游离壁。

Group B : Part posterior leaflet was excised , the defect was repaired with fresh autologous pericardial patch , then the fresh autologous pericardial item was sutured to free wall of right ventricule .

部分二尖瓣狭窄者可保留后瓣及瓣下结构，而瓣叶和瓣下结构病变严重者则应完全切除。

Some of the patients with mitral stenosis should receive mitral valve replacement with posterior leaflet and subvalvular structure preservation , however for patients with severe lesion of the leaflets the entire subvalvular structure should be resected .

结论与不保留二尖瓣后瓣下结构的MVR术比较，保留二尖瓣后瓣瓣下结构的MVR术对于MI、DVR患者更有利于改善左室构型及左室功能。

Conclusion The operation of posterior subvalvular preservation are more favorable in improving the configuration and function of left ventricle for MI and DVR patients .

我们认为心房纤颤病程长，PBMV后瓣口面积小和左房回缩差是心房纤颤复发的可能原因。

It was considered that longer atrial fibrillation history , small mitral area and higher left atrial pressure after PBMV were the key factors of atrial fibrillation recurrence .

方法回顾近10年采用后瓣环缝缩成形治疗MI的35例，其中27例合并先天性畸形，轻度MI3例，中度MI24例，重度MI8例。

Method Over the past 10 years , we performed mitral valvuloplasty with posterior annuloplasty in 35 patients , of which 27 patients were associated with congenital abnormalities , 3 patients had mild MI , 24 had moderate MI , and 8 had severe MI .

进一步观察发现，在主动脉瓣右瓣与后瓣交界以下的局部区域，可记录到有明显4相自动去极化的慢反应自律细胞样的动作电位，并可被钙通道阻滞剂Mn2＋、硝苯吡啶阻断。

Of these preparations , they were all found a very small region below the right and the poster valves , the response showed a slow and low rising phase and a marked spontaneous depolarization in phase 4 . The response could be blocked by Mn2 + and nifedipine .

结果：26例患者除1例术后瓣尖出现部分坏死外，全部Ⅰ期成活。

Results : These tongue flaps were alive in I stage except one case developed partial necrosis in the tip of the flap .

观察36例经皮球囊导管二尖瓣分离术治疗的二尖瓣狭窄患者，发现其术后瓣口面积的大小。

The mitral valve area ( MVA ) after percutaneous balloon catheter mitralcommissurotomy ( PBMC ) was assessed in36 patients with mitral stenosis .

裂孔边缘特别是后瓣多翻卷形成钩状或发夹状。

The edge of both flaps was rolled up and the posterior flap was turned up into a " hook " or " barrette " .

目的评价保留二尖瓣后瓣下结构的二尖瓣置换术对左室构型及功能的影响。

Objective To make an evaluation of the effect of mitral valve replacement ( MVR ) with the subvalvular preservation on the configuration and function of left ventricle .

5例6眼为视网膜复位术中发生，表现为角膜水肿显著并浮起，其中1眼为眼内激光时应用三面镜后瓣水肿；

在优化过程中通过合适的目标函数，保证了天线较好的频段特性，并压制干扰区副瓣、填充服务区零值、控制后瓣。

During the antenna optimization process , an appropriate fitness function is used to suppress the sidelobe in interference zone , fill the null points in service zone and control the back lobe , to get satisfactory pattern shape in the whole frequency band .

二尖瓣置换术后瓣周漏1例，半年后再手术。二尖瓣置换3年后出现下消化道出血1例。

There were 3 cases with ventricular fibrillation , 1 with cerebral infarction , 1 with valve leak after MVR and re-operation half a year later , 1 with lower gastrointestinal hemorrhage 3 years after MVR , 1 with SBE half a year after MVR and re-operation .
