Eccentric hypertrophy impairs outcome after TAVR.

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
backgroundAortic stenosis (AS) induces cardiac remodeling upon chronic left ventricular (LV) pressure overload. Here, we analyzed the clinical outcome of patients undergoing transcatheter aortic valve replacement (TAVR) for symptomatic AS with regard to varying LV hypertrophy patterns. Moreover, we investigated the genetic influence on development of different hypertrophy patterns, measured by polygenic risk scores (PRS).
methods1703 patients with severe AS undergoing TAVR were categorized according to LV mass index and relative wall thickness in four subgroups: normal geometry (NG, n = 57), concentric remodeling (CR; n = 388), concentric hypertrophy (CH; n = 993) and eccentric hypertrophy (EH; n = 265). Data was analyzed retrospectively with regard to clinical outcome. In a substudy, 520 patients affected by CH (n = 237), EH (n = 139) or CR (n = 164) were analyzed using two PRS that have been previously associated with hypertrophic and dilated cardiomyopathy.
results1 year after TAVR, for EH, in contrast to the remaining groups (NG, CR, CH), a significant difference in all-cause mortality was observable (mortality 17.4% EH, 14.0% NG, 12.4% CR, 14.0% CH, p = 0.001). This difference was observed up to 4 years (mortality 41.9% EH, 26.9% CH, 28.1% CR, 26.4% NG, p = 0.001). Of note, higher percentiles in a PRS for hypertrophic cardiomyopathy were associated with a reduced likelihood of EH in patients with AS (p = 0.046).
conclusionsThe EH group had a statistically significant poorer 1-year and 5-year outcomes than the other groups. PRS might help predict myocardial reactions in patients with aortic stenosis in future.
