Percutaneous coronary artery fistula closurein adults: Technical and procedural aspects
Bibliographic record
Abstract
BACKGROUND: Coronary artery fistulae (CAF) are an uncommon congenital anomaly characterized by an abnormal connection between the coronary arteries and cardiac chambers or vessels without traversing the usual capillary network. CAF are associated with a number of well-described symptomatic sequelae, which may necessitate treatment. With a tendency for symptoms to develop over time, symptomatic CAF may present for the first time in adulthood, with limited data existing on the technical aspects related to transcatheter fistula closure in adults. METHODS: We describe our experience in percutaneous closure of CAF in an exclusively adult population, with an emphasis on the various procedural features of device closure in this patient group. RESULTS: Attempted transcatheter CAF closure was performed in 14 patients between 1990 and 2006. Procedural success was achieved in 11 patients, with vessel tortuosity and lumen caliber important limitations in occlusion device delivery. Procedural complications included vessel dissection and device embolization. CONCLUSION: Transcatheter occlusion is a safe and effective method of therapy for symptomatic adults with CAF.

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.
