Emergency repair of proximal hard-tube connector crack during veno-arterial extracorporeal membrane oxygenation support: a case report.
Article in Frontiers in cardiovascular medicine, 2026. 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: Veno-arterial extracorporeal membrane oxygenation (V-A ECMO) is critical for patients with severe cardiac or respiratory failure. Circuit damage, particularly at the proximal hard tube connector, can lead to complications such as blood leakage and hemodynamic instability. This case report examines the repair of a crack in the proximal hard tube connector during V-A ECMO treatment. Case presentation: A 70-year-old female receiving peripheral V-A ECMO support via femoral cannulation for acute heart failure suffered a crack in the proximal hard tube connector, causing arterial blood leakage. The team performed an emergency repair using bone wax while maintaining low-flow ECMO operation. The repair was successful, and V-A ECMO support was continued without interruption, with stable hemodynamics. Conclusion: Bone wax proved effective for repairing the V-A ECMO circuit crack in this case. The low-flow operation ensured uninterrupted V-A ECMO support and maintained hemodynamic stability, offering an alternative to full circuit replacement in similar cases.
