Zero sheath exchange with VersaCross RF wire and FlexCath in cryoballoon AF ablation: A comparative study on procedural efficiency and safety.
Article in Indian pacing and electrophysiology journal. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundCatheter ablation for atrial fibrillation (AF) typically involves transseptal puncture (TSP) to access the left atrium. Traditional TSP requires sheath upsizing and exchanges, increasing procedural complexity, time, and risks. We evaluated the efficiency and safety of zero-exchange technique using the FlexCath Advance™ sheath combined with the VersaCross™ RF wire compared to the traditional method involving initial puncture with Agilis™ NxT sheath and Baylis RF needle, followed by sheath exchange.
methodsThis retrospective observational study included 109 patients undergoing their first cryoballoon AF ablation between June 2023 to June 2024 at Marshfield Medical Center. Procedural efficiency (time from venous access to TSP, time to first ablation, total procedural time), safety outcomes (pericardial effusion, bleeding, stroke/TIA, phrenic nerve injury, esophageal injury), and fluoroscopy exposure were compared between zero-exchange (n = 50) and traditional (n = 59) groups. Linear regression analyses were adjusted for age, sex, BMI, left ventricular ejection fraction (LVEF), and open-heart surgery history.
resultsThe zero-exchange approach significantly improved procedural efficiency, with shorter time from venous access to TSP (20 ± 9 vs. 28 ± 12 min; p < 0.01), time to first ablation (36 ± 9 vs. 48 ± 16 min; p < 0.01), and total procedure duration (107 ± 31 vs. 129 ± 51 min; p < 0.01). Adjusted regression analyses confirmed these reductions (all p < 0.01). Fluoroscopy time was substantially lower with zero-exchange (8.4 ± 4 min vs. 19.9 ± 8.2 min; p < 0.01). No significant complications occurred in either group.
conclusionThe zero-exchange transseptal puncture technique using FlexCath Advance™ and VersaCross™ RF wire significantly enhances procedural efficiency and reduces radiation exposure without compromising patient safety, supporting its adoption in AF ablation procedures.
