A case report of successful implantation of a leadless pacemaker via the left internal jugular vein in a patient with mirror-image dextrocardia and absence of the inferior vena cava's hepatic segment.

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
Mirror-image dextrocardia combined with absence of the hepatic segment of the inferior vena cava (IVC) and continuation of the azygos vein represents an extremely rare dual anatomical variation that significantly increases the technical complexity of leadless pacemaker (LP) implantation. This paper presents a 28-year-old male patient who required permanent pacing therapy due to third-degree atrioventricular block. Preoperative computed tomography angiography (CTA) clearly identified the aforementioned malformations. A Micra AV leadless pacemaker was subsequently implanted successfully via the left internal jugular vein. During the procedure, image mirroring technology was employed to assist the operation, ensuring precise deployment and stable parameters. This case marks the world's first successful LP implantation via the internal jugular vein in a patient with such complex anatomical variations, offering a novel, safe, and feasible approach for similar patients.
