Association Between Inferior Vena Cava Location and the Number of Deployments of a Leadless Pacemaker.

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
Introduction: While some patients faced the difficulty to implant leadless pacemaker, the relationship between inferior vena cava (IVC) location and procedural difficulty was uncertain. Methods: We conducted a single-center, cross-sectional study including 96 consecutive patients who underwent implantation of Micra leadless pacemakers between July 2022 and November 2024. Based on the positional relationship between the IVC and the right ventricular septum assessed by preprocedural computed tomography, patients were classified into right-sided and left-sided IVC groups. The primary outcome was multiple deployments defined as the number of device deployments ≥ 2. Results: A total of 96 patients were analyzed, including 81 in the right-sided and 15 in the left-sided IVC group. The mean age was 84, and 55 (57%) were male patients. Multiple deployments were observed in 39 (41%) patients. The risk of the primary outcome was significantly higher in the left-sided IVC group than in the right-sided (67% vs. 36%), with an adjusted odds ratio of 9.5 (95% CI: 1.5-58.7, Conclusions: The left-sided IVC was associated with multiple deployments of a leadless pacemaker and preoperative computed tomography was useful in assessing the procedural difficulty.
