Transposition of the Great Arteries
Bibliographic record
Abstract
The Society of Thoracic Surgeons (STS) Congenital Heart Surgery Database contains data about 3258 patients with the diagnosis of transposition of the great arteries (TGA) who underwent surgery during the 4-year time interval from July 1, 2005 to June 30, 2009, inclusive. This cohort includes 2918 patients with concordant atrioventricular connections and discordant ventriculoarterial connections and 341 patients with congenitally corrected TGA (discordant atrioventricular connections and discordant ventriculoarterial connections). The 4 most common operations were the following: (1) arterial switch operation (ASO) for TGA with intact ventricular septum (n = 1196), (2) ASO with ventricular septal defect (VSD) repair for TGA with VSD (n = 420), (3) ASO with VSD repair and aortic arch repair for TGA with VSD and hypoplastic arch (n = 55), and (4) Rastelli operation for TGA with VSD and left ventricular outflow tract obstruction (n = 49). Detailed preoperative, intraoperative, and postoperative data were obtained about patients who underwent these 4 operations. Median age at surgery (days) was as follows: ASO: 6.0; ASO with VSD repair: 7.0; ASO with VSD repair and aortic arch repair: 7.0; and Rastelli: 309.0. Mean age at surgery (days) was as follows: ASO: 22.9; ASO with VSD repair: 24.8; ASO with VSD repair and aortic arch repair: 14.4; and Rastelli: 721.8. Discharge mortality was as follows: ASO: 2.2%; ASO with VSD repair: 5.5%; ASO with VSD repair and aortic arch repair: 7.3%; and Rastelli: 0%. Median length of stay (days) was as follows: ASO: 11.0; ASO with VSD repair: 11.0; ASO with VSD repair and aortic arch repair: 18.0; and Rastelli: 7.0. The sternum was left open in the following: ASO: 24.8%; ASO with VSD repair: 29.5%; ASO with VSD repair and aortic arch repair: 40.0%; and Rastelli: 6.1%. This review of data from the STS Congenital Heart Surgery Database allows for unique documentation of patterns of practice and outcomes. From this review, we learned that although surgery for TGA is often complex and may be associated with morbidity, most patients survive without major complications.

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.
