左心室导丝起搏技术在经导管主动脉瓣置换术中的应用

Application of Left Ventricular Guidewire Pacing in Transcatheter Aortic Valve Replacement

传统上,在进行经导管主动脉瓣置换术时,通常经外周静脉将临时起搏导线置入右心室,以满足术中起搏需要。术后常规留置临时起搏导线24 h,以应对可能出现的传导阻滞和心动过缓。该方法不仅增加手术时间,而且有穿刺部位并发症以及右心室穿孔的风险。近年来,国外很多中心采用左心室导丝起搏技术替代传统的临时起搏,现对左心室导丝起搏技术做一综述。

Traditionally,during transcatheter aortic valve replacement,temporary pacing leads are inserted into the right ventricle via peripheral veins.Temporary pacemaker wires are routinely placed for 24 h after operation to deal with possible conduction block and bradycardia.This approach increases the operation time and the risk of puncture site complications or right ventricular perforation.In recent years,left ventricular guidewire pacing technique has been used in many centers to replace the traditional temporary pacing technique.This paper reviews the left ventricular guidewire pacing technique.
