Transvenous Dual-Chamber Pacemaker Implantation in a Patient with Persistent Left Superior Vena Cava Undergoing Maintenance Hemodialysis.
Article in International medical case reports journal, 2025. 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
Background: Persistent left superior vena cava (PLSVC) is a rare congenital venous anomaly. Permanent pacemaker implantation (PPI) in patients with PLSVC presents challenges in placing both the right ventricular and atrial leads. The article describes a technique for dual-chamber PPI using standard leads in a PLSVC patient with chronic kidney disease on maintenance hemodialysis. Case Presentation: A 69-year-old male patient with sick sinus syndrome (SSS), hypertension, moderate mitral regurgitation, dilated left ventricle, diabetes, chronic kidney disease (on hemodialysis), and NYHA III heart failure underwent dual-chamber pacemaker implantation via the left axillary vein. Venography revealed a persistent left superior vena cava, a challenge for the placement of leads. The ventricular lead was positioned in the right ventricular outflow tract using a Biotronik active fixation lead with a "C" shaped stylet, and the atrial lead was placed in the right atrial lateral wall. The procedure took 115 minutes with 17.5 minutes of fluoroscopy. After 4 months, the patient showed symptom improvement and stable pacing parameters. Conclusion: Dual chamber pacemaker implantation through PLSVC in a patient undergoing maintenance hemodialysis using a "C" shaped stylet technique is feasible, safe, and effective.
