Autograft dilation after Ross procedure in children and young adults is mitigated by autograft reinforcement: A retrospective MRI study.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Limited magnetic resonance imaging (MRI) data on autograft dilatation following the Ross procedure in congenital cohorts presents challenges in understanding its evolution and impact on clinical outcomes. This study, spanning from February 2003 to December 2022, included patients under 40 years at the time of the Ross procedure, with MRI follow-ups assessing dimensions at key aortic sites. Among 307 patients, 132 MRIs were analyzed from 76 individuals, revealing that autograft z-scores increase primarily with time post-procedure (Coef. 0.13; 95% CI:0.051-0.216; P = 0.002). Additionally, older patients at the time of surgery showed larger ascending aortic dimensions (Coef. 0.13; 95% CI:0.099-0.165; P = 0.001). Notably, autograft dilation at the sinus of Valsalva significantly predicted higher reintervention risks (HR 1.57; 95% CI:1.21-2.04; P = 0.001). Surgical reinforcement techniques of the autograft, via subcoronary implantation or external support, prevented such dilation (P < 0.001) and mitigated aortic regurgitation. In conclusion, our model predicted autograft dilation over time in patients after Ross procedure, aiding clinicians in making data-driven decisions regarding the optimal timing of the procedure and the selection of the most effective surgical strategy.
