Complete atrial screw lead penetration and contralateral pneumothorax post-pacemaker implantation.

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
There are some reports of atrial screw-in lead perforation, but the entire lead body is rarely exposed outside the right atrium at an early stage of the procedure. A man in his 80s had undergone catheter ablation for atrial fibrillation (AF) and had recurrent AF and tachycardia-bradycardia syndrome with 8.8 s of sinus arrest, which caused presyncope. The day after the dual-chamber pacemaker was implanted, atrial screw-in lead perforation caused an elevated threshold, a right pneumothorax, bloody pleural effusion, and pneumomediastinum. A small right thoracotomy with thoracoscopy was performed. The lead that completely penetrated the right atrial appendage and was exposed was safely retracted into the heart and removed thoracoscopically. Early surgery is essential when complete lead perforation with elevated threshold is suspected. Learning objectives: 1.Perforation of the right atrium by the screw-in lead causes contralateral pneumothorax and chest hemorrhage.2.Elevated lead threshold suggests lead perforation outside the myocardium.3.Treatment was possible with a small right thoracotomy combined with thoracoscopy.
