Valve Frame Geometry and Arrhythmia Risk Following Self-Expanding Transcatheter Pulmonary Valve Replacement.
Article in Pediatric cardiology, 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
Though major complications during transcutaneous pulmonary valve replacement (TPVR) are rare, clinically-significant ventricular arrythmia (CSVA) has been reported following self-expanding valve placement. We assess whether alterations in valve frame dimensions and geometry within the right ventricular outflow tract (RVOT) post-implantation in patients who underwent TPVR with Harmony TPV25 or Alterra contribute to CSVA risk. A single center review was performed of patients who underwent TPVR with either Harmony TPV25 or Alterra Pre-stent between August 2019 and April 2023. Using post-procedural 3D rotational acquisitions, minimum and maximum diameters were measured at 5 locations along the valve frame and perimeter and cross-sectional area (CSA) were measured closest to the pulmonary artery bifurcation and right ventricular (RV) cavity. To assess the relationship between the RVOT and valve frame, a RVOT-to-valve frame ratio together with percentage expansion, circularity and expansion ratios, and eccentricity indices were calculated. Twenty-eight patients were included (14 Harmony TPV25, 14 Alterra pre-stent). CSVA was seen more often in patients with congenital pulmonary stenosis (p = 0.02). CSVA was associated with a larger mean valve frame perimeter (118.3 vs 108.6 mm, p = 0.03) and CSA (1124.5 vs 926.2mm
