Ventricular pacing dependency after transcatheter aortic valve replacement: a prospective cohort.

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
Background: Atrioventricular conduction disturbance occurs in a significant number of patients undergoing transcatheter aortic valve replacement (TAVR). However, not all cases are ventricular pacing-dependent. Thus, we aimed to study the incidence, predictors, and outcomes of new ventricular pacing dependency (VpDep) after TAVR. Methods: We prospectively analyzed 130 consecutive transfemoral TAVR cases performed in Ramathibodi Hospital between 2015 and 2020. Three patients with prior ventricular pacing-dependent on cardiac implantable electronic devices (CIEDs) were excluded. The endpoints were VpDep at 1 month and all-cause mortality at the follow-up period end in 2021. The effects of variables on VpDep and all-cause mortality were evaluated using multivariate binary logistic regression and Cox regression analyses, respectively. First-degree atrioventricular block (AVB) was considered severe when the PR interval was >300 ms. Results: Of the 127 patients [mean age, 81.8 years; 62.2% females; 67.7% balloon-expandable (BE) device], 7 patients (5.5%) had CIEDs implanted before TAVR that were not ventricular pacing-dependent. TAVR was successfully performed in 126 (99.2%) patients. Periprocedural stroke, cardiac tamponade, and major bleeding occurred in 2 (1.6%), 4 (3.1%), and 4 (3.1%) patients, respectively. The VpDep incidence at 1 month was 7.9% (n=10) among all patients and 34.5% among those with CIEDs (n=29). VpDep was more likely to occur in patients with pre-existing right bundle branch block (RBBB) [odds ratio (OR), 21.38; 95% confidence interval (CI): 3.28-139.33; P=0.001] and severe 1 Conclusions: In this real-world cohort, pre-existing conduction abnormalities were significantly associated with a higher risk of VpDep. Mortality was similar between patients with and without VpDep.
