Right Atrial Perforation With Pericardial Effusion and Visceral Pericardial Flap Observed During Pacemaker Implantation: An Echocardiographic Case Report.
Article in Cureus, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Pacemaker implantation is a common procedure for the treatment of symptomatic bradyarrhythmias. Although generally safe, it can be associated with serious complications, such as cardiac perforation or pericardial effusion. However, right atrial wall perforation, accompanied by pericardial effusion and visualization of a visceral pericardial flap during the procedure, is an extremely rare and scarcely documented event. We report the case of a 92-year-old woman with sinus node dysfunction who developed acute hypotension during dual-chamber pacemaker implantation. Echocardiography revealed findings consistent with right atrial perforation and pericardial effusion, which were confirmed by non-contrast computed tomography. The patient evolved favorably under conservative, non-surgical management. This case illustrates an uncommon complication of pacemaker implantation and underscores the importance of immediate hemodynamic and imaging assessment during acute intraoperative events.
