Key result
Pectoral implantation of large ICDs with transvenous leads resulted in a 13% overall incidence of insulation erosion in one lead system at 50 months of follow-up.

May warrant caution with large pectoral ICDs and certain leads; leaves open prospective comparison of modern generator sizes and systems.

What is the incidence of late lead complications in patients with transvenous defibrillator leads and ICDs implanted in the pectoral region?
Absolute Event Rate: 13% vs 0%
Pectoral implantation of large ICD generators with long transvenous leads is associated with a moderate risk of late insulation breakdown due to pressure against the leads in the pocket.
Mehta et al. (1998) conducted a cohort in Pectoral defibrillator implants with transvenous leads (n=132). Pectoral ICD implantation with transvenous leads was evaluated on Lead complications (insulation erosion). Pectoral implantation of large ICDs with transvenous leads resulted in a 13% overall incidence of insulation erosion in one lead system at 50 months of follow-up.
