Comparison of outcomes following the Fontan procedure between patients with previous ductus stent and aortopulmonary shunt.
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. 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
objectivesIn this study, we aimed to compare the outcome after the Fontan procedure in patients after an initial ductus stenting or a surgical aortopulmonary shunt.
methodsWe reviewed infants with single ventricle and ductal-dependent pulmonary blood flow who underwent ductus stenting or an aortopulmonary shunt between 2009 and 2022, and subsequently underwent the staged Fontan procedure.
resultsA total of 93 patients were included (39 ductus stenting and 54 aortopulmonary shunts). Before the Fontan procedure, pulmonary artery pressure (9 vs 9 mmHg, P = 0.376) and pulmonary artery index (184 vs 183 mm2/m2, P = 0.988) were similar between the groups. However, the incidence of venovenous collaterals was higher in patients after ductus stenting than those after aortopulmonary shunt (35.9 vs 16.7%, P = 0.034). Median age (1.9 vs 1.8 years, P = 0.493) and weight at the Fontan procedure (12 vs 11 kg, P = 0.596) were similar between the groups. There was no in-hospital mortality in each group. The length of the intensive care unit stay (median 5 vs 5 days, P = 0.542) and hospital stay (median 17 vs 14 days, P = 0.767) were similar between the groups. During the median follow-up of 2.5 years, one late death was observed in the ductal stenting group. Freedom from reintervention (66.6 vs 82.0%, P = 0.095) and from adverse events (78.6 vs 92.2%, P = 0.488) at 5 years were similar between the groups.
conclusionsThis pilot study demonstrated comparable outcomes following the Fontan procedures between patients with single ventricle and ductal-dependent pulmonary blood flow after initial ductus stenting and those after initial aortopulmonary shunt.
