Right ventricular outflow tract ventricular tachycardia ablation post-Rastelli repair
Bibliographic record
Abstract
We present a case of right ventricular outflow tract (RVOT) ventricular tachycardia (VT) ablation following remote Rastelli repair. The patient was born with a double-outlet right ventricle (RV), D-transposition of the great arteries (D-TGA), a perimembranous sub-aortic ventricular septal defect (VSD), and valvular and sub-valvular pulmonary stenosis. A Blalock–Taussig shunt was created in the neonatal period, followed by a Rastelli-type repair at the age of 7 years. The latter consisted of tunnelling left ventricular flow along the patch-repaired VSD to the aorta and directing RV flow to the pulmonary artery by means of a valved homograft. The native RVOT had not been over-sewn. At the age of 21 years, the patient presented with a haemodynamically tolerated VT consistent with RVOT origin. Despite treatment with Sotalol the patient experienced a second episode with pre-syncope. Investigations included echocardiography and cardiac magnetic resonance imaging. An electrophysiology study was undertaken of all medication under minimal sedation. A decapolar catheter was inserted into the coronary sinus and quadrapolar catheters were placed at the His bundle region and at the RV apex. Atrio-ventricular Wenkebach occurred at 340 ms with no aberrant conduction. No supraventricular tachycardia was inducible with atrial programmed electrical stimulation (PES; incremental …

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.
