  • Temporary‐permanent pacemakers are associated with better clinical and safety outcomes compared to balloon‐tipped temporary pacemakers

    by Maroun Chedid, Gautam R. Shroff, Omer Iqbal, Selçuk Adabag, Rehan M. Karim

    Background: Balloon Tipped Temporary Pacemakers (BTTP) are the most used temporary pacemakers; however, they are associated with a risk of dislodgement and thromboembolism. Recently, Temporary Permanent Pacemakers (TPPM) have been increasingly used. Evidence of outcomes with TPPM compared to BTTP remains scarce.Methods: Retrospective, chart review study evaluating all patients who underwent temporary pacemaker placement between 2014 and 2022 (N = 126) in the cardiac catheterization laboratory (CCL) at a level 1 trauma center. Primary outcome of this study is to evaluate the safety profile of TPPM versus BTTP. Secondary objectives include patient ambulation and healthcare utilization in patients with temporary pacemakers.Results: Both groups had similar baseline characteristics distribution including gender, race, and age at temporary pacemaker insertion (p > .05). Subclavian vein was the most common site of access for the TPPM cohort (89.0%) versus the femoral vein in the BTTP group (65.1%). Ambulation was only possible in the TPPM group (55.6%, p < .001). Lead dislodgement, venous thromboembolism, local hematoma, and access site infections were less frequently encountered in the TPPM group (OR = 0.23 [95% CI (0.10-0.67), p < .001]). Within the subgroup of patients with TPPM, 36.6% of the patients were monitored outside the ICU setting. There was no significant difference in the pacemaker-related adverse events among patients with TPPM based on their in-hospital setting.Conclusion: TPPM is associated with a more favorable safety profile compared to BTTP. They are also associated with earlier patient ambulation and reduced healthcare utilization.
