经冠状静脉系统消融治疗室性心律失常的研究进展

Research Progress on Ventricular Arrhythmia Ablation Therapy via Coronary Venous System

起源于心外膜面和心肌深层的室性心律失常消融一直是临床上的棘手难题,冠状静脉系统作为心脏血流的回流系统,其分支广泛覆盖于整个心脏表面及心肌组织之间,可能成为辅助标测和成功消融的替代途径,近年来出现多种依赖冠状静脉系统的新型消融方式,现对相关研究进展进行综述。

Ablation of ventricular arrhythmia originating from the epicardial and intramural sites tends to be challenging in clinical practice.As the reflux system of cardiac blood flow,tributaries of the coronary venous system widely covers the surface and the myocardium tissue of the heart,which could serve as alternative access route for auxiliary mapping and ablation.This review updated the research progress on the novel ablation methods via the coronary venous system.
