Surgical retrieval and repositioning of malpositioned prosthetic pulmonic valve in a patient with situs inversus dextrocardia and tetralogy of Fallot: a case report.

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
Introduction: Percutaneous pulmonary valve implantation (PPVI) offers a minimally invasive alternative to surgical valve replacement in patients with right ventricular outflow tract dysfunction. However, valve malposition or migration can occur, necessitating surgical retrieval. Case presentation: We report a 16-year-old male with situs inversus dextroposition, mirror-image dextrocardia, and repaired Tetralogy of Fallot (TOF), who developed severe pulmonary regurgitation and underwent PPVI using a MyVal valve in another hospital. Post-procedural imaging revealed valve malposition at the right pulmonary artery bifurcation with paravalvular leakage. Surgical retrieval and reimplantation of the same prosthetic valve were successfully performed on a beating heart under cardiopulmonary bypass. Discussion: This case highlights the challenges of percutaneous interventions in complex congenital heart anatomies and the role of early surgical management in salvaging malpositioned valves. Beating-heart reimplantation minimized myocardial ischemia and facilitated rapid recovery. Conclusion: Prompt surgical retrieval and reimplantation of malpositioned PPVs can preserve valve function, reduce morbidity, and optimize outcomes in complex congenital heart disease.
