Incidence of lead erosion in a real-world cohort and a case of successful treatment with an antimicrobial mesh.

Cardiac implantable electronic device (CIED)-related infections are a major complication of CIED therapy and associated with high morbidity and mortality. The aim of the present study was to evaluate the incidence of lead erosion as one cause of the CIED-related infections and to provide detailed information about the therapy of two cases of lead erosion. We retrospectively screened the database of a large clinic specialized on patients with CIED (HIZ BERLIN Herzschrittmacher- und ICD-Zentrum, Berlin, Germany) for cases of lead erosion between 2015 and 2020. A total of 5971 outpatients were treated at the HIZ BERLIN - including 4782 patients with a one- or two-chamber pacemaker, 837 patients with an implantable cardioverter defibrillator (ICD) and 352 patients with a biventricular device for cardiac resynchronization therapy (CRT). The incidence of lead erosion was 0.033%. As one of the two patients, who suffered from lead erosions, had no signs of systemic infection, the patient received local therapy with an antimicrobial mesh and intravenous antibiotics. After twelve months, he showed a good clinical outcome without ongoing or recurring infection. In conclusion, the incidence of lead erosion is low. In case of lead erosions without signs of systemic infection, an antimicrobial mesh might be implanted as an off-label use in patients that decline complete device removal.
