Powered sheaths for lead extraction.

Abstract

Transvenous lead extraction (TLE) has seen a rapid expansion in the past 20 years. The procedure has changed from early techniques involving simple manual traction that frequently proved themselves ineffective for chronically implanted leads, and carried significant periprocedural risks including death, to the availability of a wide range of more efficacious techniques and tools, providing the skilled extractor with a well-equipped armamentarium. The reduction in morbidity and mortality associated with these new extraction techniques has widened indications to TLE from prevalent use in life-threatening situations, such as infection and sepsis, to a more widespread use even in noninfectious situations such as malfunctioning leads. Powered sheaths have been a remarkable step forward in this improvement in TLE procedures and recent registries at high-volume centers report high success rates with exceedingly low complication rates. This review is aimed at describing technical features of powered sheaths as well as reported performance during TLE procedures.
