Abstract

fetched live from OpenAlex

BACKGROUND: Dynamic coronary obstruction is a rare and potentially lethal condition, which may cause an acute coronary syndrome (ACS). CASE SUMMARY: A young patient with metastatic rhabdomyosarcoma was transferred to our center's cardiac intensive care unit with a ventricular tachycardia (VT) storm. A cardiac mass was demonstrated on transthoracic echocardiography and computed tomography. Coronary angiography was performed owing to suspected compression of the coronary arteries. Dynamic obstruction in the left anterior descending artery (LAD) was demonstrated with the use of angiography and intravascular ultrasound. After successful ostial to mid-LAD stenting, there was no recurrence of VT episodes. DISCUSSION: VT storm is a lethal condition that requires rapid diagnosis and treatment. Rarely, it can be caused by dynamic coronary obstruction.

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.
