Abstract Body (Do not enter title and authors here): Background
The optimal timing of pacemaker reimplantation following transvenous lead removal (TLR) of infected cardiac implantable electronic device (CIED) remains unclear.
Objective
Our study aimed to assess the impact of timing to pacemaker reimplantation after TLR of infected CIED on hospital outcomes.
Method
Using the Nationwide Readmissions Database, patients aged ≥18 years who underwent new pacemaker implantation with percutaneous approach following TLR of infected CIED from 2017 to 2020 were identified. The study population was stratified based on the timing of pacemaker reimplantation following TLR of infected CIED: early (<5 days) vs delayed (≥5 days). Weighted-propensity-score matched conditional multivariable logistic regressions were performed to determine the impact of the timing on various outcomes.
Results
In our study, 469 (66.9%) patients received early device reimplantation, and 232 (33.1%) patients received delayed device reimplantation (≥5 days). Post-procedurally, patients in the delayed group had a higher risk of prolonged hospital stay (95% CI OR: 42.37 (6.36 – 282.11); p<0.01) and non-home discharge (95% CI OR: 2.00 (1.35 – 2.95), p<0.01). There was no significant difference between both groups in the early mortality, 30-day readmission, and procedural complications.
Conclusion
Our study suggests that time-to-device reimplantation from TLR of infected CIED did not affect the overall short-term in-hospital outcomes. However, delayed device reimplantation was associated with a higher rate of prolonged hospital stay and non-home discharge.
