Abstract
Coronary obstruction is a major complication of transcatheter aortic valve replacement (TAVR). Rapid and growing demand for TAVR procedures is accompanied by interest in techniques that may prevent this life-threatening adverse event. BASILICA (Bioprosthetic or Native Aortic Scallop Intentional Laceration to Prevent Iatrogenic Coronary Artery Obstruction) is a transcatheter technique that may effectively prevent coronary obstruction. Formal proctorship and assistance by operators already experienced with the performance of BASILICA is beneficial to ensure good clinical outcomes. This review describes the BASILICA procedure and outlines selected technical considerations and pitfalls.AbbreviationsTAVR: transcatheter aortic valve replacement; BASILICA: Bioprosthetic or Native Aortic Scallop Intentional Laceration to Prevent Iatrogenic coronary Artery Obstruction; THV: transcatheter heart valve; VTC: virtual valve to coronary distance; ViV: valve-in-valve; VIVID: valve in valve international data.

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
