经皮跨房间隔左室辅助装置应用进展

Development of Percutaneous Transseptal Left Ventricular Assist Device

机械循环辅助在多种心脏病的治疗中起着日益重要的作用。经皮跨房间隔左室辅助装置就是一种通过经皮插管从左心房泵血到股动脉,产生连续非搏动性血流的循环辅助装置。它能降低右心室后负荷和左心室前负荷,减少心脏的做功及氧耗,同时增加血流灌注。目前主要应用于高危经皮冠状动脉介入术、急性心肌梗死、心源性休克、终末期心力衰竭、室性心律失常消融及其他诸多方面。

Mechanical circulatory support is playing an increasing important part in the treatment of varieties of heart diseases. Tandem Heart is a percutaneous circulation assist device,which can pump blood from the left atrial to the femoral artery,producing continuous non-pulsatile blood flow. It can lower right ventricular after-load and left ventricular pre-load,reduce the work and the oxygen consumption of the heart,and increase the blood flow perfusion. Presently,it is mainly used in; high risk PCI,acute myocardial infarction,cardiac shock,acute decompensated heart failure,ventricular arrhythmias ablation,and other aspects.
