二尖瓣关闭不全

All patients underwent mitral annuloplasty and 5 plus a tricuspid annuloplasty.

所有患者均有二尖瓣关闭不全，中度7例、重度5例；6例合并三尖瓣关闭不全。

Background— Mild commissural mitral regurgitation is associated with significantly higher restenosis-free surial after percutaneous mitral aluloplasty, which suggests that different mechanisms of significant MR after PM may hae different clinical courses.

背景：经皮二尖瓣成形术后严重高度非再狭窄存活率与轻度交界处损伤的二尖瓣关闭不全相关，表明经皮二尖瓣成形术后严重二尖瓣关闭不全的不同机制可能有不同的临床过程。

32 Patients over 50 years old (range 50～63) received surgical treatment.concomitant cardiac anomalys:tricuspid regurgitation in 18 patients,mitral valve regurgitation in 8,atrial tibrillation in 6,CAD in 2.preoperative ment pulmonary arterypressure Was(40.98±8.52)mmHg.All of the patients underwent Dacron or pericardia patch,18 TVR and 6 MVR,2MVP,2 patients with artrial fibrillation underwent right sided maze pricdure,and 2,CABG.

其中合并三尖瓣中重度返流18例、二尖瓣关闭不全8例、房颤6例、冠心病2例；肺动脉平均压力49.08±8.52，最高65mmHg；心功能三级10例、四级2例，采用心包补片或涤纶补片补缺损，同期行三尖瓣成形18例、二尖瓣成形术6例、二尖瓣置换术2例、右房迷宫术2例、冠状动脉搭桥术2例。

TEE revealed that balloon catheters were embedded in chordae tendineae of mitral valve 18 times in 12 patients.Except 3 cases developing moderate mitral regurgitation from mild regurgitation,the other cases didn't develop mitral regurgitation or have mitral regurgitation worsened.

TEE显示12例18次球囊导管进入左心室过程中嵌入腱索，及时退出导管。3例患者扩张后由二尖瓣轻度关闭不全转变为中度关闭不全，其余患者术后无二尖瓣关闭不全或程度无加重。

Objective To study the clinical results and operative methods of mitral valvoplasty in patients of congenital heart disease with mitral insufficiency.

目的 总结先天性心脏病合并二尖瓣关闭不全患者的二尖瓣成形手术方法和临床效果。

Congenital heart disease ; Mitral insufficiency ; Mitral valvoplasty

Methods ECG findings from 75 cases of excessive volume load of left ventricle were discriminated.QRS amplitude variability was studied from 3 diseases such as mitral and aortic insufficiency and patent ducts arteriosus.

采用75例左室容量负荷过重病因的心电图鉴别，研究二尖瓣关闭不全、主动脉瓣关闭不全及动脉导管未闭等3种疾病的QRS振幅变化特征。

Abstract］ Objective To identify the effect of ECG for the etiological diagnosis of heart disease and investigate some differential diagnosis criteria of ECG.Methods ECG findings from 75 cases of excessive volume load of left ventricle were discriminated.QRS amplitude variability was studied from 3 diseases such as mitral and aortic insufficiency and patent ducts arteriosus.

目的 了明确心电图对心脏病病因诊断的作用，探讨ECG的某些鉴别诊断标准方法采用75例左室容量负荷过重病因的心电图鉴别，研究二尖瓣关闭不全、主动脉瓣关闭不全及动脉导管未闭等3 疾病的QRS振幅变化特征。

We have firstly calculated and compared the different flow rates by applying various aliasing velocities in the patients with mitral insufficiency, mitral stenosis and ventricular septal defect as well, and suggest that the most uitable aliasing velocities for the hemisphierical flow cenvergence calculation were about 46cm/sec for mitral insufficiency, 37cm/sec for mitral stenosis and 58cm/sec for ventricular septal defect respecively.

首次在二尖瓣关闭不全、二尖瓣狭窄和室间隔缺损患者采用不同混叠极限速度分别计算、比较其流量，提出二尖瓣关闭不全、二尖瓣狭窄和室间隔缺损患者最适合半球血流会聚法计算流量的混叠极限速度分别为46、37和58cm/sec左右。

Objective To investigate the effects of interleukin-1 β converting enzyme gene on the biologic characteristics of ovarian cancer cells.

目的 探讨白细胞介素-1 β转换酶的表达，对卵巢癌细胞生物学特性的影响。
