Echocardiographic Features of Cardiomyopathies: A Comprehensive Review
Bibliographic record
Abstract
Cardiomyopathies represent a heterogeneous group of myocardial diseases characterized by structural and functional abnormalities that can lead to heart failure, arrhythmias, and sudden cardiac death. Echocardiography remains the first-line, non-invasive imaging modality for the evaluation of cardiomyopathies, owing to its broad availability, safety profile, and diagnostic versatility. This review comprehensively outlines the echocardiographic features associated with the major morphofunctional subtypes of cardiomyopathy: dilated cardiomyopathy (DCM), hypertrophic cardiomyopathy (HCM), restrictive cardiomyopathy (RCM), arrhythmogenic right ventricular cardiomyopathy (ARVC), and left ventricular non-compaction cardiomyopathy (LVNC). Emphasis is placed on both adult and pediatric populations, with attention to age-specific diagnostic criteria and measurement standards. The article also includes structured tabular summaries to facilitate clinical interpretation and application across diverse patient settings. Through an integrated and standardized echocardiographic approach, this review aims to support accurate diagnosis, effective monitoring, and informed therapeutic decision-making in the management of cardiomyopathies.

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; both teacher heads agree on what is shown here.
