Incidence and Predictors of Successful Lead Extraction With Short Active Mechanical Extraction Sheaths Only.
Article in Journal of cardiovascular electrophysiology, 2026. 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
BACKGROUND AND
aimsTransvenous lead extraction (TLE) is increasingly performed for malfunction or infection of cardiac implantable electronic devices (CIED). Active mechanical rotational sheaths facilitate extraction and are available in short and long sizes, but it is unclear how many patients short active mechanical extraction sheaths (SAMES) are sufficient for TLE, and in which patients they may facilitate TLE. This study aimed to evaluate the incidence and predictors of successful lead extraction using only SAMES.
methodsWe retrospectively analyzed patients who underwent TLE at the University Hospital Zurich from 2013 until 2023 regarding the use of short or long active mechanical extraction sheaths, as well as clinical and radiological success and complications.
resultsA total of 568 TLEs were performed from January 2013 until December 2023. In 55 cases (9.7%), TLE was successful using only SAMES. Independent predictors for successful lead extraction using only SAMES in multivariate analysis were shorter lead dwell time (OR: 0.98, 95% CI: 0.97-0.99, p < 0.001) and use of anticoagulation (OR: 0.44, 95% CI: 0.19-1.00, p = 0.05). Complications occurred at a lower rate when only SAMES were used (All complications 12.7% vs. 24.2%, minor complications 9.1% vs. 18.7%, perioperative death 0% vs. 1.7%).
conclusionIn 10% of patients undergoing TLE, SAMES are sufficient for successful lead extraction. SAMES may be a sensible choice as the primary extraction tool in patients with chronic anticoagulation and shorter lead dwell time, as these factors predict a higher likelihood of success in TLE with SAMES only.
