Extraction of sterile leads is the preferred approach rather than implanting a new lead: the con perspective.

摘要

Lead malfunction is a common problem in implantable cardiac device patients and is expected to increase with the aging of leads. There is a weak indication for extraction of superfluous leads with the potential for cardiac implantable electronic device interference and abandoned or redundant leads; much remains to be learned from clinical practice. Lead extraction, although safe in experienced hands, remains a high-risk procedure, especially in lower-volume centers and/or when performed by lower-volume operators. Therefore, a strategy of abandoning nonfunctioning leads is reasonable, and lead extractions should be reserved for cases with system infection or high lead burden.
