The comparison between the novel technique and conventional method in the catheter ablation of premature ventricular contractions originating from the free wall of tricuspid annulus.

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
backgroundThis study aimed to assess the safety and effectiveness of a novel technique for catheter ablation in patients with premature ventricular contraction (PVC) from the free wall of tricuspid annulus (TV). HYPOTHESIS: We hypothesized that the novel technique is more efficacious than the traditional approach.
methodsWe retrospectively investigated 59 consecutive patients with PVC originating from the free wall of TV between January 2013 and November 2021. The patients were divided into two groups: the reversed S-curve technique group (RST, n = 26) and the reversed C-curve technique group (RCT, n = 33). The RST under the support of a steerable sheath was used in RST group, while the RCT under the support of a nonsteerable sheath was used in the RCT group. Systematic mapping and radiofrequency ablation were preferentially performed under the valve in all patients.
resultsCompared to the RCT group, total procedural time and fluoroscopic exposure time were significantly shorter in RST group. Two patients experienced cardiac tamponade in the RCT group, while no complications were observed in RST group (p = .498). The success rate was significantly higher in RST group compared to RCT group (81.9% vs. 100%, p = .029). Three patients in RCT group failed to ablate during the operation but were successfully ablated using the novel method. During regular follow-up, no patients in the RST group had a recurrence, while three patients in the RCT group did (p = .274).
conclusionsIt suggests that the reserved S-curve technique, supported by a steerable sheath, is a feasible and effective method for ablating PVC originating from the free wall of TV.
