AB  - BACKGROUND: Cardiac resynchronization therapy (CRT) is a recognized treatment for 
      severe heart failure. The recommended left ventricular (LV) lead position is at 
      the lateral or posterolateral wall. However, LV leads cannot always be implanted 
      at the expected site. The aim of our study was to describe in a large series of 
      patients the anatomical position really achieved by LV leads at implant. METHOD: 
      In consecutive patients referred for CRT, we determined the LV lead implantation 
      success rate, the success rate for the initial target vein, and the final 
      position achieved by the tip of the LV lead in the left and right anterior 
      oblique projections. RESULTS: Ninety patients (66 men, 71 +/- 9 years, 20% New 
      York Heart Association (NYHA) class IV) were referred for an LV lead implantation 
      between September 2003 and March 2006. A LV lead could be implanted in 92% of 
      patients. In 70%, LV leads were implanted in the initial target vein. The final 
      location was lateral or posterolateral in 68% and anterior or anterolateral in 
      32% of patients. The mean procedural time was 117 +/- 42 minutes. CONCLUSIONS: LV 
      lead implantation was achieved in 92% of patients with mean procedure duration of 
      less than 2 hours. Nevertheless, 30% of LV leads were implanted outside of the 
      initial target vein and 32% at the anterior or anterolateral wall. Further 
      studies are warranted to compare the responder rate to CRT when the LV lead is at 
      the lateral or posterolateral wall or when the LV lead is at an alternative site.
