Initial experience of transoesophageal echocardiography-guided percutaneous pulsed field ablation of atrial fibrillation.
Article in Open heart, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
objectivePulsed-field ablation (PFA) is a new technology of catheter ablation for atrial fibrillation (AF). This research is to investigate the feasibility of a new strategy (transoesophageal echocardiography-guided pulsed field ablation, TEEP) to guide PFA for AF with no contrast and zero fluoroscopy.
methodsPatients with AF underwent TEEP under general anaesthesia with the guidance of three-dimensional (3D) transoesophageal echocardiography (TEE) throughout the procedure. After a successful transseptal puncture, the PFA catheter (CardiPulse) was delivered to the different pulmonary veins sequentially for standard PFA, and the pulmonary vein electrical isolation (PVI) was observed in real-time. After the ablation, left atrial bipolar voltage mapping under sinus rhythm was performed to verify the PVI.
results10 patients with AF were enrolled, including 6 patients with paroxysmal AF and 4 patients with persistent AF. The mean operative time was 99±14 min, the mean time of the left atrial manoeuvre was 66±23 min, and the mean PFA ablation time was 105±8 s. First-pass PVI of all veins was achieved in all patients, thus no additional PFA applications were needed after the initial set. No contrast was needed and no X-ray was exposed. No complications were observed.
conclusionsWe report the preliminary application of 3D TEE-guided PFA for AF in the world. Its immediate safety and efficacy are promising. Compared with traditional PFA procedures, TEEP has many advantages, including accuracy of the transeptal puncture, direct visualisation of contact between the catheter and myocardial tissue, no contrast and zero fluoroscopy.
