Background To date, left ventricular (LV) pacing via transvenous implantation has an overall success rate ranging from 90.0% to 95.9%.Surgical epicardial LV leads represent an alternative for cardiac resynchronization therapy (CRT)if transvenous lead implantation fails.The aim of this study was to assess whether LV pacing via limited thoracotomy would be feasible and safe and could improve heart function in a long-term follow-up when used on a routine basis for those cases in which standard transvenous procedures proved to be ineffective or unsatisfactory.
