Introduction Temporary epicardial pacing wires (TEPW) are used in the immediate postoperative cardiac surgery period for the identification, diagnosis, and treatment of acute arrhythmias. They are usually removed before discharge, but are sometimes clipped and left to retract into the skin and are thus retained. Rare complications from these retained wires have been documented in numerous case reports. We describe a case of a 57-year-old man with chronically draining wounds due to infected retained pacing wires. This case prompted a systematic review of these patients to delineate complications and to create a novel treatment algorithm. Methods The authors conducted a systematic review of MEDLINE, Embase, and the Cochrane Library databases and retrieved relevant, English-language articles published between 1986 and 2018. Two reviewers critically appraised the studies that met inclusion and exclusion criteria. Results Thirty-one articles met inclusion criteria with a total of 35 patients included. The existing articles represent either level IV or level V evidence. Mean ± SD time of presentation from initial TEPW placement was 4.9 ± 5.9 years, with a range of 1 month to 24 years and 77% of patients were symptomatic. The TEPW wire migration occurred in 74% of patients, with invasion into vasculature, visceral organs, and subcutaneous tissue. Most of the patients who underwent wire removal had complete recovery. The relevant literature suggests that there is a wide range of complications, and migration is more often associated with need for surgical intervention. Conclusions In patients with severe symptoms or evidence of migration, surgical intervention and removal should be strongly considered to prevent potentially deadly complications. We propose an algorithm to minimize these complications based on a literature analysis in accordance with PRISMA guidelines.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
