The effect of adding an open distal anastomosis to proximal aneurysm repairs in bicuspid aortopathy.
Article in General thoracic and cardiovascular surgery, 2023. 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
objectivesTo determine the role of adding open distal anastomosis to proximal aortic aneurysm repairs in bicuspid aortic valve (BAV) patients.
methodsRetrospective review was performed of 1132 patients at our Aortic Center between 2005 and 2019. Inclusion criteria were all patients diagnosed with a BAV who underwent proximal aortic aneurysm repair with open or clamped distal anastomosis. Exclusion criteria were patients without a BAV, age < 18 years, aortic arch diameter ≥ 4.5 cm, type A aortic dissection, previous ascending aortic replacement, ruptured aneurysm, and endocarditis. Propensity score matching in a 2:1 ratio (220 clamped: 121 open repairs) on 18 variables was performed.
resultsMedian follow-up time was 45.6 months (range 7.2-143.4 months). In the matched groups, no significant differences were observed between the respective open and clamped distal anastomosis groups for Kaplan Meier 10-year survival (86.9% vs. 92.9%; p = 0.05) and landmark survival analysis after 1 year (90.6%; vs. 93.3%; p = 0.39). Overall incidence of aortic arch-related reintervention was low (n = 3 total events). In-hospital complications were not significantly different in the open with respect to the clamped repair group, including in-hospital mortality (2.5% vs. 0.5%; p = 0.13) and stroke (0% vs. 0.9%; p = 0.54). In multivariable analysis, open distal anastomosis repair was not associated with long-term mortality (Hazard Ratio (HR) 1.98; p = 0.06).
conclusionWe found no significant inter-group differences in survival, reintervention, or in-hospital complication rates, with low rates of mortality, and aortic arch-related reintervention, suggesting adding open distal anastomosis may not provide benefit in BAV patients undergoing proximal aortic aneurysm repairs.
