Peri-procedural anesthesia and patient pain experience in pulmonary vein isolation by means of very high-power short-duration radiofrequency ablation.
Article in Journal of interventional cardiac electrophysiology : an international journal of arrhythmias and pacing, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 6 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
backgroundVery high-power short-duration (vHPSD) temperature-controlled radiofrequency ablation (vHPSD) may reduce ablation times and improve patient tolerability, permitting pulmonary vein (PV) isolation under mild conscious sedation. We evaluated of the anesthetic drugs use and patients' pain experience during vHPSD PV isolation.
methodsFifty-eight patients, with paroxysmal and persistent atrial fibrillation (AF), treated with QDot Micro catheter and vHPSD (90 w for 4 s) (vHPSD group), were compared with the last 33 patients treated with a surround flow contact force-sensing catheter guided by the ablation index (450 anteriorly at 50 W, 330 posteriorly at 40 W) (AI group). Anesthetic drugs use was compared as well as pain experience, measured using a 0-10 scale.
resultsAll PVs were acutely isolated. Procedural time (78 ± 10 min vs 84 ± 12 min, p = 0.012), fluoroscopy time (369 ± 139 s vs 441 ± 172 s, p = 0.03), and RF time in the vHPSD group (8.3 ± 2.1 min) were shorter than in the AI group (25 ± 11 min, p < 0.001). Only 4 patients experienced an access site-related vascular complication (groin hematoma). Midazolam was required in 36 (62%) vHPSD group patients vs 31 (94%) AI group patients (p < 0.001). Fentanyl was required in 4 (7%) vHPSD group patients vs 25 (76%) AI group patients (p < 0.001). No patients required general anesthesia. Twenty-two (38%) vHPSD group patients underwent PV isolation without any anesthetic drug. Pain experience was significantly lower in vHPSD group (4.9 ± 2 vs 6.6 ± 1.8, p < 0.001).
conclusionsvHPSD radiofrequency ablation for PVI can be performed under conscious sedation using only benzodiazepine in most of patients without compromising patient pain experience.
