1 · What the graph read from it

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.

2 · The registry

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

High-power, short-duration (HP-SD) ablation is a well-established radiofrequency (RF) ablation protocol in cardiac electrophysiology. Recently, very high-power, short-duration (vHP-SD) ablation has emerged as an alternative. This study compares lesion metrics between vHP-SD and HP-SD ablation protocols using the latest irrigated RF catheter with temperature-based power regulation, considering the impact of contact force (CF). RF ablations were performed in a porcine ex vivo model using myocardial preparations in a circulating saline bath. Three protocols were applied: vHP-SD (90 W for 4s), HP-SD-4 (50 W for 4s) and HP-SD-15 (50 W for 15s). A total of 360 lesions in 12 hearts were analyzed (vHP-SD: 120; HP-SD-4: 120, HP-SD-15: 120). The HP-SD-4 protocol produced the lowest mean lesion depth (2.42 ± 0.61 mm vs. 3.16 ± 0.41 mm vs. 4.49 ± 0.66 mm, p < 0.001), mean maximum lesion diameter (6.02 ± 1.00 mm vs. 7.34 ± 0.92 mm vs. 9.13 ± 1.59 mm), and mean lesion volume (52.0 ± 22.5 mm³ vs. 96.4 ± 28.8 mm³ vs. 211.4 ± 95.3 mm³, p < 0.001), followed by the vHP-SD protocol. In contrast, the HP-SD-15 protocol resulted in the highest values across all three parameters. Lesion depth, maximum lesion diameter, and lesion volume increased significantly with higher contact force (p < 0.001, p = 0.002, and p = 0.003, respectively). However, the absolute changes in these lesion dimensions were relatively small compared to those observed with power-controlled RF catheters, likely due to the effect of temperature-based power regulation.
