Death and vascular tears occur in up to 1% of the patients undergoing lead extraction procedures. These complications are due to abnormal force vectors during the procedure. The investigators postulate that use of bidirectional traction (superior and inferior directions) and feedback from a digital force gauge is associated with minimal lead displacement compared to conventional lead extraction. Lead displacement is an indirect risk factor for potentially fatal lead extraction complications
