Postcardiotomy extracorporeal membrane oxygenation after elective, urgent, and emergency cardiac operations: Insights from the PELS observational study.
Article in JTCVS open, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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: Outcomes in cardiac surgery are influenced by surgical priority, with higher mortality in emergency cases. Whether this applies to postcardiotomy venoarterial (VA) extracorporeal membrane oxygenation (ECMO) remains unknown. This study describes characteristics and outcomes of patients undergoing cardiac operations and requiring VA ECMO, stratified by emergency, urgent, or elective operation. Methods: This retrospective multicenter observational study included adults requiring postcardiotomy VA ECMO between 2000 and 2020. Preoperative and procedural characteristics, complications, and survival were compared among the 3 patient groups. The association between emergency surgery and in-hospital survival was investigated through mixed Cox proportional hazard models. Results: The study cohort comprised 1063 patients (52.2%) with elective operations, 445 (21.8%) with urgent operations, and 528 (26%) with emergency operations. Emergency operations included more coronary artery bypass grafting operations (n = 286; 54.2%; Conclusions: One-quarter of postcardiotomy VA ECMOs are implemented after emergency operations. Despite more complications in emergency cases, in-hospital and 5-year survival are comparable between emergency, urgent, or elective operations.
