Abstract

fetched live from OpenAlex

Introduction: Bioprosthetic mitral valve thrombosis (BPMVT) following post-operative extracorporeal membrane oxygenation (ECMO) is a rare complication with high mortality. Case Report: A 75-year-old man with a flail posterior mitral leaflet underwent a bioprosthetic mitral valve replacement and was subsequently placed on central veno-arterial high flow ECMO following intractable shock after protamine administration. He developed BPMVT over the following 48 hr, which did not resolve with 3 weeks of systemic heparin. He was then treated successfully with 3 days of continuous low dose (1 mg/hr) Tissue Plasminogen Activator (TPA). He suffered no bleeding consequences and had a complete cardiac and end-organ recovery. Discussion: Slow TPA infusion may be an acceptable treatment strategy for alleviating thrombotic burden from a bioprosthetic valve, even in the post-operative setting.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
