Surgical outcomes of repair for tetralogy of Fallot with a previous right ventricular outflow tract stent.
Article in Annals of pediatric cardiology. 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
Background: The optimal management of neonates with tetralogy of Fallot (TOF) and unfavorable anatomy remains debated. Early primary repair carries risks, while palliative options such as right ventricular outflow tract (RVOT) stenting have emerged as effective alternatives to conventional shunts. However, outcomes of corrective surgery following RVOT stenting remain underexplored. Patients and Methods: A retrospective study was done on 11 patients with TOF who underwent RVOT stenting followed by surgical repair between April 2021 and March 2025, from a total of 619 TOF surgeries. Data on demographics, intraoperative findings, pulmonary artery (PA) growth, and postoperative outcomes, including 30-day mortality, were collected. PA growth was assessed via Results: The median age and weight at surgery were 31 months and 10.2 kg, respectively. Complete stent excision was possible in 91% of patients. Transannular patch repair was required in 90.9% of cases. Prestent PA Conclusions: Corrective surgery after RVOT stenting in TOF is safe and feasible, with favorable early outcomes. Early repair - preferably within 5 months of RVOT stenting - facilitates optimal PA growth and minimizes surgical complexity. Larger, prospective studies are warranted to standardize timing and assess long-term outcomes.
