The Removal, Excision, Sterilization, and Quarantine (RESQ) Method is a Feasible Alternative Treatment for Cardiac...

Current guidelines recommend that all infected cardiac implantable electronic devices (CIEDs) should be removed. However, financial or anatomical concerns can lead to management of infection with simple debridement, as opposed to complete removal. In this observational study, we report the outcomes of our modified procedure for this real-world dilemma.

The Quarantine (RESQ) method is characterized as follows: the removal (R) of all non-essential foreign materials, including old sutures and leads; the excision (E) of all non-viable, chronically inflamed, granulation, or scar tissue; the sterilization (S) of the remaining generator; and the quarantine (Q) of a new pocket in the sub-muscular layer for reimplantation. From a review of electronic medical records, 30 patients were selected and divided into three groups according to the intervention used: RESQ (n = 9) in group A, simple debridement (n = 16) in group B, and guideline-recommended replacement (n = 5) in group C. Patient baseline characteristics were similar between the groups. After analyzing the proportion of patients that were free from infection one year following their respective interventions, we found that group A performed better than group B (100% and 31.2% infection-free, respectively, p = 0.001), and was comparable to group C (both 100% infection-free, p = not applicable).

The RESQ method is a feasible and beneficial alternative for selected patients with CIED infections who are unable to receive a generator replacement according to the recommended guideline.
