Persistent Left Superior Vena Cava in an Adult Presenting With Atrial Fibrillation.
Article in Cureus, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Persistent left-sided superior vena cava (PLSVC) is usually an asymptomatic, rare congenital anomaly, but has been associated with atrial arrhythmias due to remnant pacemaker tissue within the vessel. This report describes a 62-year-old male who presented with new-onset atrial fibrillation (AF) and was incidentally found to have a PLSVC draining into a dilated coronary sinus, along with additional thoracic and vascular abnormalities, including a bovine aortic arch and tracheal diverticulum. Transthoracic echocardiography with agitated saline injection and computed tomography confirmed the diagnosis. The patient's AF self-terminated and was managed medically, with referral for outpatient electrophysiology follow-up given the recognized association between PLSVC and supraventricular arrhythmias. This case highlights the importance of recognizing PLSVC during the evaluation of AF, the utility of multimodality imaging in establishing the diagnosis, and the need for further studies to clarify the arrhythmogenic potential of PLSVC and the role of targeted electrophysiologic intervention in adults.
