Prognostic Impact of Residual Renal Congestion at Discharge After Transcatheter Aortic Valve Implantation.
Article in CJC open, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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: Residual pulmonary congestion after transcatheter aortic valve implantation (TAVI) has been linked to adverse outcomes. However, whether renal congestion, assessed by intrarenal venous flow (IRVF), is associated with outcomes remains unclear. Methods: This study enrolled 164 patients with aortic stenosis who underwent TAVI, and assessed IRVF before TAVI and at discharge (48-72 hours before discharge). The IRVF patterns were categorized as continuous (non-congestive) or discontinuous (congestive). The primary endpoint was a composite of all-cause death or heart failure rehospitalization. Results: Before TAVI, 126 patients (76.8%) had a continuous pattern, and 38 (23.2%) had a discontinuous pattern; at discharge, the numbers were 134 (81.7%) and 30 (18.3%), respectively. Over a median follow-up of 698 days, the primary endpoint occurred in 37 patients (22.6%). A discontinuous pattern at discharge was associated with a higher incidence of events than a continuous pattern (log-rank Conclusions: A discontinuous IRVF pattern at discharge, indicating residual renal congestion after TAVI, was associated with an adverse prognosis.
