D-PO03-095 - A Novel Entirely Extracardiac Temporary Pacing System Without Post-procedural Bedrest Restrictions (ID 318)

Abstract

Background: Patient immobilization imposed with temporary intracardiac pacing can result in clinical complications and economic burden. A completely extracardiac temporary pacing lead may provide an alternative pacing modality that does not require patient immobilization or bed rest restrictions.
Objective: The purpose of this study was to evaluate the effects of posture and in-hospital ambulation tests during temporary pacing with a novel, completely extracardiac lead.
Methods: In this prospective single-center study, patients who underwent a permanent pacemaker implant or replacement were simultaneously implanted with the extracardiac temporary pacing system. The effects of posture (supine, left/right lateral decubitus and upright) on electrical performance and appropriate pacing/sensing during in-hospital ambulation tests were evaluated 1- and 2-days post-implant.
Results: Eleven patients (64% male, 67.7 ± 9.4 years, BMI 25.9 ± 3.5 kg/m2) were successfully implanted with cardiac capture on Day 0. Cardiac capture was possible in all postures in 10 out of 11 patients on Day 1 and 2. Failure to capture occurred in one patient due to presumed lead dislodgement. Changes in posture did not affect mean pacing thresholds by more than 1.6 V on Day 1 and 1.9 V on Day 2. Appropriate sensing and pacing were also observed during in-hospital activity in all patients undergoing ambulation tests.
Conclusion: Temporary pacing performance using a completely extracardiac lead was minimally impacted by post-procedural posture changes and in-hospital ambulation. These results suggest that bedrest restrictions and patient immobilization may not be necessary with an extracardiac pacing lead.
