The Genetic and Imaging Key to Understanding Bicuspid Aortic Valve Disease
Bibliographic record
Abstract
Bicuspid Aortic Valve (BAV) is a prevalent congenital heart defect, characterized by the presence of two cusps instead of three, leading to significant clinical implications such as aortic stenosis, regurgitation, and aneurysms. Understanding the genetic underpinnings of BAV is essential for early diagnosis and management, which can prevent severe complications like aortic dissection and heart failure. Recent studies have identified critical genes associated with BAV, including NOTCH1, GATA4, GATA5, SMAD6, NKX2.5, BMP2, and ROBO4, all of which play vital roles in aortic valve development and function. Imaging advancements, particularly in cardiac MRI and echocardiography, have enhanced the assessment of valve morphology and hemodynamics, with Wall Shear Stress emerging as a promising biomarker. This review consolidates current genetic and imaging research, elucidating the contributions of genetic variants to the etiology and progression of BAV, while emphasizing the importance of imaging biomarkers in clinical management. The findings aim to improve genetic screening strategies, facilitate early diagnosis, and guide the development of targeted therapies for individuals with BAV.

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.
