Routine Versus Selective Temporary Epicardial Pacing Wire Placement: A Scoping Review

Temporary epicardial pacing wires (TEPWs) are used widely for rhythm management in cardiac surgery. However, their routine placement is being debated increasingly because of low utilization and potential procedural risks. We compared routine versus selective TEPW placement practices and assessed the utilization, complications, and predictors of pacing need. A scoping review was conducted in accordance with the PRISMA-ScR guidelines. We searched PubMed, Embase, Scopus, and Cochrane Library until June 2025. Studies were included if they examined TEPW strategies in adult or pediatric cardiac surgery and reported outcomes related to wire use, complications, or predictors of pacing need. Eleven studies involving 16,874 patients (14,957 adults, 1,917 children) were included. Routine placement rates ranged from 73.5% to 89.9%, but utilization was low at 2.9%-29.6%. Selective strategies showed higher utilization of 30%-100% with fewer unused wires. Predictors of the need for TEPW included intraoperative arrhythmias, prolonged CPB, and complex procedures. Complications were rare. Thus, routine TEPW placement often leads to unnecessary wire use. Selective strategies based on intraoperative and clinical predictors may optimize patient care. Developing a risk-based tool could enhance decision-making and reduce procedural burden.
