Ascending aortic aneurysm and dissection risk: focus on aortic height index.
Article in Interdisciplinary cardiovascular and thoracic surgery, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
objectivesAcute aortic dissection (AAD) commonly occurs with a dilation of the ascending aorta at diameters under the threshold of surgical indication. Aortic diameter/height index (AHI) has been proposed for risk stratification and more accurate prophylactic surgery.
methodsFrom January 2001 to November 2023, all patients operated on for AAD at our Institute were prospectively collected and retrospectively analysed, calculating the AHI. A Control Group without aortic pathology was stratified for the same risk index, and a modelling risk analysis for aortic dissection was also performed.
resultsA group of 210 patients was operated during the study period, of whom 168 (80%) had a prevalent post-junctional aortic dilation with a mean aortic diameter at the time of diagnosis of 5.1 ± 0.7 cm. In 53/210 (25%), the aortic diameter was > 5.5 cm. According to AHI, 19/210 patients (9%) were low-risk, 142/210 (67.6%) moderate, 45/210 (21.3%) high and 4/210 (2%) severe risk. In the AHI probability density function, the peak for dissection was 2.93 cm/m for males and 3.05 for females. Control were 6343 patients (3.2% at moderate risk) with AHI of 2.01 cm/m. After simulating the dissecting process, 215 (3.3%) had AHI ≥ 2.9 cm/m.
conclusionsThe measurement of the aortic diameter to height index in patients with acute aortic dissection revealed a significant prevalence of individuals presenting a moderate risk for acute aortic events. Regardless of absolute aortic diameter values, patients with AHI exceeding 2.9 cm/m should be referred to an aortic centre for multidisciplinary risk assessment.
