【摘要】 心脏再同步化治疗（cardiac resynchronization therapy,CRT）可以改善心力衰竭患者的临床症状，并逆转心室重塑，降低患者死亡率，然而仍有少数患者在CRT植入后表现为无应答。左室起搏电极的植入部位对接受CRT的患者预后至关重要。本文综述冠状静脉、心肌瘢痕、室壁运动这几类影响左室起搏电极植入的因素，归纳总结了目前克服以上或其他多种因素指导左室电极植入的研究，旨在为提高CRT应答率提供更高效更全面的策略。更多还原

【Abstract】 Cardiac resynchronization therapy(CRT) can improve the clinical symptoms, reverse the ventricular remodeling, and reduce the mortality in patients with advanced heart failure. However, a few patients still show non-response to CRT implantation. The implantation site of left ventricular pacing electrode is critical for the prognosis of patients undergoing CRT. This paper aims to make a comprehensive review about the factors affecting left ventricular pacing electrode implantation, including coronary veins, myocardial scar, ventricular wall motion, etc. The researches for overcoming many of the above factors in guiding left ventricular pacing electrode implantation are summarized, so as to provide more effective and comprehensive strategies for upgrading response to CRT.(J Intervent Radiol, 2023, 32: 825-828)更多还原
