High-Resolution CT-Based Virtual Simulation of an Unruptured Sinus of Valsalva Aneurysm for Aortic Root Reimplantation: A Case Report.
Article in Surgical 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
introductionValve-sparing aortic root replacement (VSRR) for sinus of Valsalva aneurysm (SVA) is rarely reported due to technical challenges. In this case report, high-resolution CT data were used for 3D computer graphics (3DCG) visualization and precise measurement of aortic root geometry, facilitating VSRR in a patient with a markedly disproportionate, unruptured SVA. CASE PRESENTATION: A 36-year-old female experienced heart failure at delivery. Echocardiography revealed an SVA involving a dilated noncoronary sinus (NCS) (43 mm) extending over the right atrium, a dilated sinotubular junction, and moderate aortic regurgitation (AR). To assess the feasibility of VSRR, electrocardiogram-gated CT data were analyzed in 2 ways. First, multiplanar reconstruction of CT images allowed measurement of the virtual basal ring area (566.6 mm
conclusionsThis case demonstrates successful aortic root reimplantation for an unruptured SVA. CT-based aortic root visualization and measurement provided clear virtual images, facilitating surgical planning and increasing confidence in performing valve-sparing procedures for SVAs with unusual anatomy.
