A 60-year-old female with heart failure with reduced left ventricle ejection fraction, implantable cardiac defibrillator and left bundle branch block was admitted to Department of Cardiology for cardiac resynchronization therapy defibrillator upgrade. Due to difficulties with advancement of left ventricular lead to lateral coronary vein, balloon angioplasty with use of retrograde approach via collateral branches and two CS sheaths positioning was performed. Final position of lead in lateral vein was achieved resulting with pacing threshold of 0.7 V/0.5 ms, impedance of 720 Ω and QRS of 130 ms.
一位 60 岁女性，患有心力衰竭伴左心室射血分数降低、植入式心脏除颤器和左束支传导阻滞，因左心室导线推进至侧冠状静脉困难而被收入心内科行心脏再同步治疗除颤器升级。通过逆行途径使用侧支分支和两个 CS 鞘管进行球囊血管成形术，最终将导线置于侧静脉内，起搏阈值为 0.7 V/0.5 ms，阻抗为 720 Ω，QRS 为 130 ms。
