AB  - OBJECTIVES: Cardiac resynchronization therapy (CRT) is a well-established method 
      that improves the clinical symptoms and long-term prognosis of specific heart 
      failure (HF) patients by restoring systolic synchronicity and enhancing 
      myocardial function. However, the high rate of intraoperative and postoperative 
      left ventricular (LV) lead dislocation limits its application to a great extent. 
      The aim of this study was to demonstrate the long-term safety and effectiveness 
      of a new approach named the loop technique for patients who experience repeated 
      intraoperative transvenous LV lead dislocations during CRT. METHODS: The current 
      study was a single-centre, prospective, nonrandomized controlled trial. 
      Forty-four HF patients who underwent CRT were included. All patients were 
      followed to death or 3 years. RESULTS: Among 44 HF patients, 36 underwent the 
      traditional operation, and 8 underwent the loop technique due to repeated 
      intraoperative LV lead dislocations. Intergroup comparison revealed no 
      significant differences between the two groups with respect to most preoperative 
      indices, intraoperative pacing and sensing parameters. At the end of the 3-year 
      follow-up, 4 (11.1%) patients in the traditional operation group and 2 (25.0%) 
      patients in the loop technique group had died. There was no significant 
      difference in the mortality rate (P = 0.30). No complications related to this new 
      technique were observed, such as intracoronary thrombosis, infection or 
      dislocation. Intergroup comparison showed no significant difference in the New 
      York Heart Association (NYHA) class, echocardiography indices, N-terminal pro 
      brain natriuretic peptide (NT-proBNP) level or pacemaker programming parameters. 
      CONCLUSIONS: The loop technique is a safe and effective alternative method for 
      patients who experience repeated intraoperative transvenous LV lead dislocations 
      during CRT.
