Comparative Effects of HTK and St. Thomas Cardioplegia on Myocardial Outcomes and Sodium Balance in Pediatric Tetralogy of Fallot Surgery.
Article in Journal of multidisciplinary healthcare, 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
Objective: This study aimed to evaluate the myocardial protective efficacy of different myocardial protection solutions used during extracorporeal circulation in pediatric patients undergoing surgery for complex congenital heart disease. The analysis focused on the effects of these solutions on perioperative cardiac rhythm and serum sodium levels. Methods: A retrospective analysis was performed on clinical data from 60 pediatric patients who underwent surgery with extracorporeal circulation for complex congenital heart disease between January 2022 and October 2024. Patients were categorized into the St. Thomas cardioplegic solution group (n = 30) and the histidine-tryptophan-ketoglutarate (HTK) solution group (n = 30). Serum sodium levels and myocardial enzyme markers were monitored perioperatively. Additionally, the incidence of postoperative cardiac arrhythmia and the duration of cardiac reperfusion were recorded. Results: No significant differences in serum sodium concentrations were observed between the groups preoperatively, or at 12 and 48 hours postoperatively ( Conclusion: Compared with St. Thomas cardioplegic solution, the HTK solution was associated with significant intraoperative fluctuations in serum sodium concentrations, which stabilized postoperatively. HTK solution demonstrated improved myocardial protection as evidenced by reduced cardiac reperfusion time and lower postoperative myocardial enzyme levels, without an increased risk of postoperative cardiac arrhythmias.
