Cardiac Structural Remodeling and Hemodynamic Patterns Following Transcatheter Aortic Valve Replacement.
Article in Cureus, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Background Transcatheter aortic valve replacement (TAVR) is increasingly utilized for most patients with symptomatic severe aortic stenosis. TAVR is linked to enhanced long-term cardiac hemodynamics, reversal of left ventricle (LV) hypertrophy, and improved aortic valve gradients. We present a retrospective observational study assessing cardiac remodeling and valvular flow patterns post-TAVR. Methods Retrospective echocardiographic data were collected, evaluating cardiac function and valvular flow patterns before and after TAVR at a single institution. Data was compiled and statistically analyzed using a paired t-test evaluating variations at approximately 30 days and one-year post-TAVR. Results On echocardiogram 30 days and one-year post-TAVR, there was a reduction in LV mass index from 132 g/m² to 110 g/m² (95%CI: 98-122; p=0.01) and 118 g/m² (95%CI: 102-133; p=0.03), and a reduction in relative wall thickness from 0.54 to 0.49 (95%CI: 0.46-0.52; p=0.05) and 0.44 (95%CI: 0.38-0.49; p=0.03), respectively. Doppler velocity indices (DVI) increased from 0.24 to 0.61 (95%CI: 0.49-0.73; p<0.001) and 0.57 (95%CI: 0.48-0.65; p<0.001). Expected improvement in aortic valve velocities and gradients were observed post-TAVR. Conclusions Following TAVR, LV remodeling can be observed as early as 30 days. This is demonstrated by a reduction in LV mass index and relative wall thickness in conjugation with an anticipated improvement in valvular flow patterns and flow across the aortic valve.
