Predictors of Long-Term Survival Following Transvenous Extraction of Defibrillator Leads

Abstract

Despite high rates of procedural success, infectious indication for ICD lead extraction is associated with increased long-term mortality. In contrast, among patients undergoing extraction for lead failure, long-term survival was excellent. The presence of procedural failure was a significant predictor of long-term mortality. Further studies will be necessary to better understand the mechanisms by which procedural failure may adversely impact long-term outcomes.

Predictors of short‐term mortality in patients undergoing a successful uncomplicated extraction procedure

“…The low mortality rates in the noninfectious group are similar to previous studies 20 . This is not surprising as these procedures are almost never performed urgently, patients are usually younger with less comorbidities and without infection.…”

Impact of ICD lead on the system durability, predictors of long‐term survival following ICD system extraction

“…Multivariate factors associated with increased mortality were primarily patient‐related: increasing age, lower NYHA class, lower left ventricle ejection fraction, renal failure, and infection. The comparable risk factors and 1‐year survival after ICD lead extraction were reported in the literature . In our study patients with ICD leads extracted for infective indications have the highest mortality rate in the long term follow‐up.…”

Procedural outcomes and long‐term survival following lead extraction in octogenarians

“…While LE for infectious indication is associated with worse 30‐day mortality as compared to other indications for LE, the outcomes of LE in the octogenarians was similar to the younger cohort of patients. The lower prevalence of diabetes in the octogenarians as compared to nonoctogenarians (19% vs 30.6%, P = 0.018) could have partly offset the higher risk associated with the presence of CIED‐related infection.…”
