Comparative analysis of ultrasound-guided versus fluoroscopy-guided venous puncture techniques for pacemaker implantation.
Article in Heart and vessels, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Ultrasound-guided pacemaker puncture allows for visualization of vascular anatomy in real time, potentially reducing complications; however, detailed comparative studies with the traditional fluoroscopy-guided technique are lacking, particularly those incorporating objective imaging endpoints such as postoperative computed tomography (CT). In this study, we aimed to compare the procedural time and complications associated with fluoroscopy- and ultrasound-guided axillary and subclavian vein puncture techniques for pacemaker lead implantation. We conducted a retrospective analysis of 250 patients who underwent DDD pacemaker implantation for symptomatic bradycardia at Sakakibara Heart Institute between January 2021 and December 2023. The patients were categorized into two groups: fluoroscopy-guided (Group X, n = 147) and ultrasound-guided axillary or subclavian vein puncture (Group E, n = 103). The demographic data, number of punctures, and number of complications were analyzed. Among the 250 patients, postoperative chest CT scans were available for 75 to assess lead placement, focusing on intrathoracic lead insertion and distance from the lead to the outer edge of the clavicle. The mean age of the patients was 82 years, 46% were male, and the mean body mass index was 22 kg/m
