Systematic Review and Meta-Analysis of Acute Mortality and Complication Rates Following Leadless Pacemaker Placement Using National-Level Data
Background and Objectives: Leadless pacemakers provide an innovative alternative to traditional transvenous pacemakers for managing cardiac arrhythmias. The objective of this systematic review is to conduct a meta-analysis comparing acute complication and mortality rates associated with leadless pacemakers versus transvenous pacemaker placements using national-level data. Specifically, we aim to summarize the current evidence and calculate pooled odds ratios for acute overall complications, acute device-related complications, and acute mortality to assess the early safety outcomes of leadless pacemaker placement relative to traditional transvenous pacemakers. Materials and Methods: A systematic search of PubMed, Scopus, ScienceDirect, and Google Scholar was conducted by two independent researchers using a predefined search protocol. The search included articles published up to 10 October 2024, without limits on review depth. Studies were included if they provided national-level data comparing leadless pacemaker and traditional pacemaker recipients in terms of acute mortality, acute overall complications, and acute device-related complications. Outcomes were pooled to calculate odds ratios using a random-effects model in RStudio (version 2024.12.1+563). Results: A total of five studies met the eligibility criteria. The pooled odds ratio for acute mortality was 2.03 (95% CI: 0.65–6.34, I2 = 99%; p < 0.01), for acute overall complications was 1.08 (95% CI: 0.45–2.61, I2 = 99%; p < 0.01), and for acute device-related complications was 1.02 (95% CI: 0.23–4.44, I2 = 99%; p < 0.01). Conclusions: The reviewed studies suggest that leadless pacemakers offer a promising alternative to transvenous pacemakers, offering a comparable short-term safety profile. Ongoing technological advancements may further enhance their applicability in clinical practice.

Temporary Pacing with Active-Fixation Leads: Clinical and Economic Impact Versus Conventional Temporary Transvenous Pacing
Background/Objectives: The use of temporary pacemakers is increasing every year. Conventional temporary pacemakers are connected to the myocardium via a passive-fixation lead (temporary pacing with passive fixation leads; TPPF), which compromises their effectiveness and safety. Off-label active-fixation systems (temporary pacing with active fixation leads; TPAF) are a safer alternative. The main objective of this study was to assess the clinical and economic impact of TPAF versus TPPF. Methods: We conducted a literature search based on the clinical outcomes of both pacing techniques. We then carried out a descriptive comparative analysis and extrapolated the results to the Spanish, European, and global populations. Results: Of the 1015 articles located, the analysis included five articles from ECTSF and eight from ECTEFA, prospective and focused on the recording of complications. It is estimated that the implementation of ECTEFA as the first option for ECT would lead to a 94.7% reduction in complications. In economic terms, it would mean a 55.72% reduction in the cost of the procedure. Conclusions: TPAF leads to considerable clinical improvement compared with TPPF. Furthermore, while the price of TPAF doubles the procedural cost, the reduced cost of hospital stays and treating complications means the active-fixation systems could substantially reduce the overall cost of temporary pacing for healthcare systems.

A Leadless Intracardiac Transcatheter Pacing System
A series of 725 patients underwent attempted implantation of a leadless transcatheter pacemaker. At 6 months, 96.0% of patients had no major device-related complications, and 98.3% had a low and stable pacing capture threshold.
For more than half a century, permanent cardiac pacing for symptomatic bradycardia has been achieved with systems that consist of a surgically implanted subcutaneous electrical generator connected to one or more transvenous leads that deliver the pacing therapy to the heart. Although these devices are effective, approximately one in eight patients has an early complication, frequently related to the lead or leads or to the subcutaneous “pocket.”

Complications include problems with the subcutaneous pocket, such as hematomas and infections; lead-insertion problems, such as pneumothoraxes and hemothoraxes; lead dislodgements and integrity problems; infections, including septicemia and endocarditis; vascular obstructions; and reduced . . .
