Transcatheter aortic valve implantation and implantation of other transcatheter heart valves, generally requires insertion of a temporary venous pacemaker. Implantation of a temporary venous pacemaker adds complexity, time and risk to the procedure. Guidewire modification to allow pacing is increasingly popular, however it requires technical expertise and provides unipolar pacing resulting in high thresholds and potential capture loss. The Wattson temporary pacing guidewire is a novel device which offers guidewire support for valve delivery and concomitant bipolar pacing. It may offer a safe and effective solution to guidewire pacing for transcatheter aortic valve implantation and other transcatheter heart valve implantations. Herein, we review the literature surrounding left ventricular guidewire pacing along with the features and clinical data of the Wattson wire.
经导管主动脉瓣植入术以及其他经导管心脏瓣膜植入术通常需要插入临时静脉起搏器。植入临时静脉起搏器会增加手术的复杂性、时间和风险。通过对导丝进行改进以实现起搏功能的方法越来越普遍，然而这需要专业技术，并且会提供单极起搏，导致阈值较高且可能出现夺获失败。Wattson临时起搏导丝是一种新型装置，它为瓣膜输送提供导丝支持并同时进行双极起搏。它可能为经导管主动脉瓣植入术及其他经导管心脏瓣膜植入术的导丝起搏提供一种安全有效的解决方案。在此，我们回顾了有关左心室导丝起搏的文献以及Wattson导丝的特点和临床数据。
