Stereotaxis公司开发出治疗心率不齐的新技术

  
一种新型磁性导航系统能够帮助医生远程控制细小导管进入心脏和临近血管，治疗心率不齐。

这种Stereotaxis技术使用磁体在体外远程引导导管进入心脏。心血管医生能够通过远程控制来精确定位导管，抵达心脏病变的确切部位。然后通过导管运动来消融或者治疗心脏，阻断异常信号的发放。

心率不齐是因为心脏正常电脉冲的次序发生改变而引起的。这会导致心脏泵功能的效率下降。如果心率不齐时间较长，会导致心脏节律变的太慢、者太快或者发生漂移。

美国Abbott西北医院的Minneapolis心脏研究所心血管医生William Katsiyiannis指出：“Stereotaxis为我们提供了把导管引导和放置在心脏任何部位或者相邻血管的能力，包括那些令人难以置信的困难部位或者以前的技术所不能达到的部位。这种技术能够改变目前我们治疗需要心脏介入治疗患者的现状。”Minneapolis心脏研究所是得到公认的世界领先心脏研究所之一。

 Stereotaxis实验室位于Abbott西北医院。这套Stereotaxis系统是由美国Stereotaxis公司 研制开发的。
 
New Technology to Treat Arrhythmias
 
A new digital magnetic navigation system helps doctors to remotely steer small catheters throughout the heart and surrounding vessels to treat cardiac arrhythmias.

This Stereotaxis technology uses magnets outside the body to guide catheters inside the heart by remote control. Cardiologists can then precisely position the catheters via remote control to reach the exact location where the heart is malfunctioning. The catheter is then activated to ablate or treat the area in the heart by disrupting the abnormal signals.

Cardiac arrthymias are caused by a change in the normal sequence of electrical impulses in the heart. This can cause the heart to pump less effectively. If arrhythmias last for some time, they may cause the heart rate to be too slow or too fast or the heart rhythm to be erratic.

“Stereotaxis offers us the ability to guide and place a catheter anywhere in the heart or surrounding vessels, including incredibly difficult or previously inaccessible locations,” noted William Katsiyiannis, M.D., a cardiologist with the Minneapolis Heart Institute at Abbott Northwestern Hospital (Minneapolis, MN, USA). “This technology has the potential to change how we treat patients who require interventional cardiac procedures.” The Minneapolis Heart Institute is recognized internationally as one of the world’s leading heart institutes.

The Stereotaxis laboratory is located in Abbott Northwestern Hospital. The Stereotaxis system was developed by Stereotaxis, Inc. (St. Louis, MO, USA).
