Abstract
OBJECTIVES: To evaluate the efficacy and safety of the new device Amplatzer Duct Occluder II (ADO II) for the closure of coronary artery fistulae (CAF) with coronary anomaly. BACKGROUND: Transcatheter device closure is an alternative treatment for selective patients with CAF. The currently available reports regarding the closure of CAF with the ADO II are limited. METHODS: From April 1, 2011 to July 15, 2012, 5 patients (3 males and 2 females) aged from 3 years to 27 years old (median age 5 years old) underwent CAF closure with the ADO II. The immediate and short-term outcomes were evaluated. RESULTS: ADO II was deployed via the femoral vein (2 cases), femoral artery (1 case), brachial artery (1 case), and radial artery (1 case). There were no complications during all the procedures. The median fluoroscopy and procedural times were 20 and 39 minutes, respectively. Immediate trivial and mild residual shunt was present in one patient, respectively, but disappeared 24 hours after the procedure, and there was no recanalization at a median follow-up of 6 months. CONCLUSIONS: The new device ADO II was safely deployed with complete resolution of CAF shunt with tortuous coronary artery to the drainage. The reduced sheath sizes and softer shape of this device allow for venous or arterial approach. The ADO II might be a preferable alternative device for closure of small-tortuous CAFs.

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 it
