Radial-Sectional CT for Tricuspid Valve Intervention Planning: A 4-Patient Clinical Case Series.
Article in JACC. Case reports, 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
backgroundIsolated tricuspid regurgitation (TR) is an independent mortality predictor. Despite improved surgical outcomes, complex tricuspid valve anatomy makes precise repair challenging. We evaluated the utility of computed tomography (CT) with radial-sectional view (RSV) for procedural planning and postoperative assessment. CASE SERIES: Four patients with severe TR underwent surgical repair. Preoperative CT-RSV, generated using standard imaging workstations, provided a comprehensive anatomical map. Radial planes centered on the septal leaflet visualized coaptation gaps with anterior/posterior leaflets, the location of prolapse, and the severity of tethering. This "virtual surgery" enabled individualized strategies. In all cases, tricuspid valve repair was performed according to CT-based planning, resulting in marked reduction of TR.
conclusionsCT-RSV provides a reproducible and accessible roadmap. By detailing septal-centric anatomy, it facilitates clearer visualization of leaflet and subvalvular structures compared with transesophageal echocardiography and enables reproducible quantitative assessment, thereby supporting individualized surgical planning and informing treatment strategy selection.
