<scp>J</scp>‐tip guide wire entrapment within the heart during central venous catheterization
Bibliographic record
Abstract
A 55-year-old female was hospitalized for melena. The patient was suspected of having uremia symptoms. Use of a tunneled cuffed hemodialysis catheter of the right internal jugular vein was planned. At one point, the wire could not be extracted or advanced. In addition, whenever the guide wire was manipulated, ventricular premature rhythms developed. Fluoroscopy revealed knotting of the guide wire in the right ventricle. A 7 French guiding catheter was inserted along the guide wire, which loosened the knotting of the guide wire. The present case shows that entrapment within the heart can develop due to use of a J-tip guide wire. If a guide wire cannot be removed despite several attempts with gentle pressure, this event should be ruled out by fluoroscopy and chest X-ray. Using of straight or curved guide wire and real-time surveillance using fluoroscopy or electrocardiography may be important to prevent this complication.

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
