The Mitralign system A breakthrough in mitral valve repair Mitralign系统 二尖瓣修复技术的突破
A weakened heart 虚弱的心脏可能会变大
may become enlarged causing the left ventricle to dilate 并导致左心室扩张
and mitral regurgitation to occur 以及二尖瓣关闭不全
The Mitralign system repairs functional mitral regurgitation Mitralign系统通过标准的心脏介入技术
with standard interventional cardiology techniques 修复功能性二尖瓣关闭不全
Mitralign minimally invasive percutaneous procedures Mitralign微创手术
is deployed using a system with catheters and wires 籍由导管导线辅助完成
A guide catheter is delivered through the aortic valve 引导导管穿过主动脉瓣之后
and placed on the posterior side the left ventricle 被置于左心室后侧
Echocardiography is used to confirm wire placement 通过超声心动图可以确认
in the mitral annulus 导线是否被正确置于二尖瓣瓣环上
A second wire is delivered 第二根导线
through a double-lumen bident catheter 通过一个双腔双钩导管引入
followed by the pledget catheter 接着是棉线导管
which delivers the pledget across the mitral annulus 负责将棉线穿过二尖瓣瓣环
the catheter extrudes half the pledget on the eight real side 导管将棉线的一半挤出有八个面的褶皱
then the pledget singed 之后烧结棉线
The ventricular side the pledget is extruded and singed 位于心室侧的的棉线被以同样的方式挤出并烧结
The catheter is that removed 然后导管会被移除
The delivery at the second pledget follows the same steps 另一根导线处通过同样的步骤进行处理
The pledget inside and placated or pull together 之后两根棉线会被拉到一起
Once the plications confirmed a stainless steel lock is deployed 拉紧的程度调整完毕后，一把不锈钢小锁会将棉线线头锁定
securing the pledget in place 以确保两个棉线线头的相对位置不会变化
If necessary the same steps are followed on the opposite side of the annulus 如果有必要，手术还可以在二尖瓣瓣环另一侧同样进行
With the Mitralign system the circumference of the annulus is reduced 通过Mitralign系统技术，二尖瓣瓣环的周长可被有效减小
relieving the symptoms of regurgitation 以减轻的二尖瓣关闭不全的症状
while preserving future clinical options for patients 同时也为未来进一步进行的外科手术治疗提供了可能
Mitralign, a front-line therapy for cardiologists Mitralign, 心脏病治疗的前沿技术
a lifeline for patients 患者的生命线
