The mitral valve and its contribution to the generation of left ventricular outflow tract obstruction in hypertrophic cardiomyopathy: Considerations for surgeons
Bibliographic record
Abstract
Hypertrophic cardiomyopathy is increasingly understood to be a disease that presents not only with septal hypertrophy but also with diverse anomalies of the mitral valve and subvalvular apparatus. In this review, we describe the involvement of the mitral valve in the generation of left ventricular outflow tract obstruction in patients with hypertrophic cardiomyopathy, and discuss the surgical approaches to managing this complex condition. La cardiomiopatía hipertrófica está cada vez más entendida como una enfermedad que se presenta no solo con evidencia de hipertrofia septal, sino también con diversas anormalidades de la válvula mitral y su aparato subvalvular. En este artículo describimos la contribución de la válvula mitral a la generación de la obstrucción del tracto de salida del ventrículo izquierdo en pacientes con cardiomiopatía hipertrófica obstructiva, además de discutir los diferentes abordajes quirúrgicos disponibles para tratar esta compleja patología.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
