Permanent pacemaker dependency after transcatheter aortic valve implantation: Prevalence, patients' characteristics, and main determinants.
Article in Heart rhythm O2, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Background: Permanent pacemaker implantation (PPI) remains a complication of transcatheter aortic valve implantation (TAVI). The evolution of conduction disturbances and long-term pacemaker dependency (PD) still represents a matter of investigation. Objective: This study aimed to study the prevalence, patients' characteristics, and predictors of PD after TAVI. Methods: We analyzed consecutive patients who underwent TAVI included in a prospectively maintained single-center database. Results: We included 376 patients (median age 82 years [78-84]; 51% men). Sixty-nine (18%) underwent PPI after TAVI; among those evaluated at 12 months (n = 59), 21 (36%) were PD. PD patients had preprocedure longer QRS duration (110 ms [90-130] vs 90 ms [80-100], Conclusion: PPI is frequent after TAVI, with ∼36% of these patients being PD at 12 months. Chronic kidney disease, baseline QRS duration, and intraventricular conduction disturbances are strong predictors of the need for permanent pacemaker ventricular stimulation.
