Abstract
Electromechanical dyssynchrony is an important consequence of and contributor to ventricular dysfunction. Echocardiography can be useful to assess the mechanisms underlying mechanical dyssynchrony, to evaluate the impact of mechanical dyssynchrony on ventricular function, and to try to predict the therapeutic response to cardiac resynchronization therapy (CRT). Mechanical dyssynchrony has been demonstrated in several pediatric acquired and congenital cardiac conditions, but experience is still limited. Moreover, the optimal method to identify dyssynchrony remains unclear, and data predicting the response to CRT in pediatrics are lacking. Understanding mechanisms of electromechanical dyssynchrony by echocardiography seems promising, at least in left bundle branch block (LBBB), but may be limited in children due to the uncommon occurrence of LBBB in this population. This review addresses the commonly used methods to diagnose mechanical dyssynchrony, discusses the emerging concepts on the mechanisms of the various types of mechanical dyssynchrony, and discusses the possible significance of mechanical synchrony in pediatric and acquired congenital heart disease.

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
