A Rare Cardiac Complication of Chest Trauma: Right Coronary Artery – Right Atrium Fistula in a Teenager
Bibliographic record
Abstract
This report describes a 19-year-old male who sustained multiple chest stab wounds during a house party altercation, resulting in traumatic injury to the right coronary artery (RCA) and a fistula to the right atrium (RA). Coronary angiography showed RCA dilation with communication to the RA, coronary sinus, and right ventricle (RV), while cardiac computed tomography (CT) angiography identified an RCA pseudoaneurysm with an RA fistula, confirmed intraoperatively. The patient was stabilized and underwent successful open-heart surgery involving RCA ligation and coronary artery bypass grafting (CABG). This case emphasizes diagnostic challenges and surgical management of traumatic RCA pseudoaneurysm with fistulous communication.

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.
