Does the reduced left ventricle ejection fraction affect the results of transvenous lead extraction?

Reduced left ventricle ejection fraction (LVEF) is a common risk factor of complications in patients undergoing different procedures.

The aim of the study was to assess  efficiency and safety of transvenous lead extraction (TLE) procedures in patients with reduced LVEF (< 40%) compared to patients with mid-range reduced and preserved LVEF (≥40%).

Data from 3434 of TLE procedures (patient"s age during TLE-65,5 ± 15,5 years, female; 1168 (34,01%), performed in two high volume European Centers (PISA – Italy, Lublin-Zamość – Poland) were analysed.

In group with reduced LVEF (A) compared to the group of patients with LVEF ≥ 40% (B) the smaller number of female was found (p < 0,001). The number of devices with ICD leads was higher in group A (p < 0,001). Dwelling time for oldest lead and the oldest extracted lead were longer in group B (p < 0.001).  There were no differences in indications for TLE between presented groups. The procedure duration time was similar in both groups. There were no statistically significant differences in complete procedural success, clinical success, major and minor complications and procedure related death occurrence. Complete results are presented in  Table.1

The effectiveness and safety of TLE in patients with reduced left ventricle ejection fraction does not differ from the results of the TLE procedures in patients with mid-range reduced and preserved LVEF.
