3.
Objective To evaluate the effects of percutaneous balloon mitral valvotomy (PBMV) for mitral stenosis (MS) with mitral regurgitation (MR).
结果术后左心房平均压、肺动脉压力、心功能NYHA分级分别比手术前减少了50·9%、20·8%、21·3%(P<0·05);二尖瓣口面积、EF值分别比手术前增加了119·5%、9·8%(P<0·05);左心房最大直径、左心室最大直径分别比手术前减少了2·1%和1·2%(P>0·05);二尖瓣返流和手术前比较并没有增加。

2.
Objective Primary investigate whether reduce the moderate-severe tricuspid regurgitation after the left cardiac surgery, the surgical indication to tricuspid annuloplasty was considered in patients tricuspid annulus diameter≥21mm/m~2; the multiple factor analysis for the influence factor of the tricuspid annulus and tricuspid regurgitation in patients with left cardiac valve disease.
目的 初步观察以三尖瓣瓣环径／体表面积≥21作为三尖瓣成形手术的指征是否有助于减少左心瓣膜置换手术患者术后中--重度三尖瓣返流的发生；对影响左心瓣膜病患者三尖瓣瓣环径及三尖瓣返流的因素进行初步分析。
补充资料：在AutoCAD中偏心圆锥与偏心圆台实体的画法
现在要画一个偏心圆锥,底面在WCS的XY平面上,圆心(0,0,0),半径100,顶点(300,0,400)在ZX平面上.
1)连接PA,PB. A(-100,0,0) B(100,0,0)
图1
在当前坐标下:
2)延长PA到C,使PA=CA;延长PB到D,使PB=DB;
3)连接CD;
4)以CD为直径画圆;
5)用XLINE命令中的二等分选项作角CPD的角平分线PO,交CD于O;
6)过O作CD的垂线,交圆于E,F;
图2
7)用三点UCS命令,取三点为:O,P,C;
8)过点O作PO的垂线GO,交PC于G;
图3
9)再次用三点UCS命令,取三点为O,F,G;
10)现在就可以画椭圆锥了!
cone-e-c-捕捉O点-捕捉F点-捕捉G点-a-捕捉P点;
图4
11)回到WCS,剖切椭圆锥
SL-选择椭圆锥-回车-XY-回车-捕捉P点.
12)删除辅助线条.
