Transvenous Lead Extraction in Adult Patient with Leads Implanted in Childhood-Is That the Same Procedure as in Other Adult Patients?

Background: Lead management in children and young adults is still a matter of debate. Methods: To assess the course of transvenous lead extraction (TLE) in adults with pacemakers implanted in childhood (CIP) we compared 98 CIP patients with a control group consisting of adults with pacemakers implanted in adulthood (AIP). Results: CIP patients differed from AIP patients with respect to indications for TLE and pacing history. CIP patients were four-eight times more likely to require second-line or advanced tools. Furthermore, CIP patients more often than AIP were prone to developing complications: major complications (MC) (any) 2.6 times; hemopericardium 3.2 times; severe tricuspid valve damage 4.4 times; need for rescue cardiac surgery 3.7 times. The rate of procedural success was 11% lower because of 4.8 times more common lead remnants and 3.1 times more frequent permanently disabling complications. Conclusions: Due to system-related risk factors TLE in CIP patients is more difficult and complex. TLE in CIP is associated with an increased risk of MC and incomplete lead removal. A conservative strategy of lead management, acceptable in very old patients seems to be less suitable in CIP because it creates a subpopulation of patients at high risk of major complications during TLE in the future.
