Feasibility, timing and outcome of leadless cardiac pacemaker implantation in patients undergoing cardiac implantable electronic device extraction.
Article in Clinical research in cardiology : official journal of the German Cardiac Society, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled it.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundPatients requiring extraction of infected or dysfunctional cardiac implantable electronic devices (CIED) have high morbidity and mortality. The Micra™ leadless cardiac pacemaker (LCP) may be beneficial for patients requiring permanent pacemaker therapy after CIED extraction.
methodsThis study aimed to assess the feasibility, timing and outcomes of LCP implantation in patients who underwent CIED extraction due to infection or dysfunction. The local Micra™ LCP registry was reviewed for LCP implantations and CIED extractions.
resultsMicra™ LCP implantation was scheduled for 48 consecutive patients (21 women, 44%) undergoing CIED extraction for infection (n = 38, 79%) or dysfunction (n = 10, 21%), and feasible in 47 (98%). Complete CIED removal was feasible in 44 patients (92%) and in 37/38 patients with infected CIED (97%). Overall, 32 LCP (67%) were implanted in a single procedure: 3 (6%) before and 13 (27%) after CIED extraction. LCP were implanted in a single procedure in 24/38 patients (63%) with infected CIED and in 8/10 patients (80%) with dysfunctional CIED. The in-hospital mortality rate was 6% (n = 3), and the survival rates at 30 days, 90 days and 1 year were 94% (n = 45/48), 90% (n = 43/48), and 85% (n = 41/48), respectively. No recurrent LCP-related mortality or infections occurred during a median follow-up of 15 (interquartile range, 12-41) months.
conclusionTwo-thirds of LCPs could be implanted in a single procedure with CIED extraction; no recurrent infections were detected. Overall, Micra™ LCP implantation in patients requiring CIED extraction was feasible.
