Table 4 shows an significant increase (p=0.041) in complete success rates of the pace/sense leads with adhesions up to the RV when extracted with the new Evolution R/L Sheath (83.3% vs 45.5%). When there was no adhesion in the RV, both sheaths had similar complete success rates in case of extracting a pace/sense or high voltage lead. Table 5 Output of multivariate analyses
