Transcatheter treatment of coronary artery disease and atrial septal defect with sequential implantation of coronary stent and Amplatzer septal occluder: Preliminary results
Bibliographic record
Abstract
Coronary stent implantation had been established as a highly effective revascularization technique in patients with occlusive coronary artery disease. Transcatheter closure of atrial septal defects is becoming a definite alternative to surgery in properly selected patients. During a 19-month period, 6 patients (50% women; mean age, 58 +/- 17 years; range, 32-73 years) of a consecutive series of 176 prospective multicenter registry patients undergoing transcatheter atrial septal defect closure were treated with sequential percutaneous coronary revascularization and Amplatzer septal occluder implantation. Indication for revascularization was stable angina in four patients and unstable angina in two. Indication for defect closure was significant left-to-right shunt with right ventricular enlargement. Defect diameter ranged from 13 to 20 mm by transesophageal echocardiography, and the stretched diameter measured 13 to 25 mm. Procedural success of both interventions was achieved in all cases without in-hospital complications. A total of seven stents were successfully implanted in five coronary vessels. No stent was used in one patient after successful PTCA. Immediate total closure of the defect was obtained in five patients. Trivial residual shunting, observed in one patient, disappeared at 24 hr. No adverse cardiac events, recurrence of anginal symptoms, or evidence of residual shunt were observed at clinical and echocardiographic follow-up, which ranged from 60 to 390 days (mean, 258 +/- 150 days). These results suggest that sequential transcatheter therapy of coronary artery disease and atrial septal defect is safe and efficacious in selected patients.

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.
