Prolonged lead dwell time and lead burden predict bailout transfemoral lead extraction.

Femoral approach TLE is associated with increased risk of 30-day procedure related major complications but not 30-day all-cause mortality. Prolonged lead dwell time and increased number of leads extracted are independent predictors for bailout transfemoral lead extraction. Such patients should be considered high risk of major complications and performed by high-volume lead extraction centers with experience in multiple approaches and techniques including experience with transfemoral lead extraction.
