Transjugular Leadless Pacing in Massive Biatrial Dilation: A Straight Path to the Heart.

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
backgroundPermanent pacing in patients with severe tricuspid regurgitation (TR) and distorted right heart anatomy is challenging, particularly when future valvular intervention is likely. CASE SUMMARY: A 75-year-old man with permanent atrial fibrillation, prior mitral valve repair, massive biatrial enlargement, severe secondary TR, and symptomatic bradycardia with chronotropic incompetence required permanent pacing. Because conventional transvenous lead implantation was expected to be technically difficult and potentially unfavorable in the setting of severe TR and possible future valve intervention, a leadless pacemaker was selected. Owing to extreme atrial enlargement and altered right heart geometry, implantation was performed via the right internal jugular vein to improve catheter control and facilitate septal deployment. The procedure was successful, and pacing parameters remained stable at 8-week follow-up. DISCUSSION: Leadless pacing avoided a transvalvular lead and preserved future tricuspid treatment options. TAKE-HOME MESSAGE: Leadless transjugular pacing is a useful option in patients with distorted anatomy who may require future valvular repair.
