Surgical strategies in Ebstein anomaly: 28 years' experience in a pediatric hospital.
Article in Archivos de cardiologia de Mexico, 2024. 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
objectivesEbstein's anomaly is a congenital defect characterized by a lack of delamination and apical displacement of the tricuspid valve, tricuspid insufficiency, right atrial enlargement, and ventricular dysfunction. To analyze the results and evolution of the different surgical strategies, data were collected from 45 patients operated on during 1990-2018. Twenty-six patients were included with a median age at initial surgery of 11.3 years (range: 13 days-18.6 years).
methodProcedures were plastic 10 patients (38%), cone technique reconstruction 11 (42%), and replacement 5 (19%). Additional interventions were required in 7 patients: cavo-pulmonary anastomosis 4 and Cox-maze 4. Nine patients (34.6%) required reoperation due to severe tricuspid insufficiency. Six had previous plastic, two bioprothesis, and one, cone.
resultsOverall mortality was 11.5% (3) at a median of 10.1 years post-surgery (range: 5.7-10.12) associated with arrhythmias (p = 0.05), right (p = 0.008), left (p = 0.0001) ventricular dysfunction and reoperations (p = 0.03). None were previous conus. Median follow-up was 6.5 years (range: 1-29.1). Ninety-one-point-six percent were in functional class I/II and 79.2% in sinus rhythm.
conclusionsThe results of the different classic techniques were similar, although not free of complications and reoperations. Cone reconstruction proved to be effective, with low surgical mortality, less need for reoperations, and durability in the medium term.
