Iatrogenic ST Elevation during Percutaneous Closure of a Coronary Artery Fistula
Bibliographic record
Abstract
Coronary artery fistulae are an uncommon anomaly and, while frequently asymptomatic, may require interventional therapy. Transcatheter approaches for closure of coronary artery fistulae are now commonly used, with various methods of fistula occlusion described, including detachable coils. During a percutaneous procedure to occlude a symptomatic left anterior descending coronary artery to pulmonary artery fistula, the patient experienced chest discomfort with anterior ST segment elevation. We demonstrate an unusual, unique and striking ECG abnormality complicating the delivery of coils designed to occlude the fistula in the absence of coronary artery injury. The mechanisms of the procedural ECG changes are discussed, as are potential alternate diagnoses and associated therapy.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
