Clinical Dilemma: Recurrent Syncope With Isolated Left Ventricle Non-Compaction Cardiomyopathy and Preserved Ejection Fraction, a Case Report and Review of the Literature
Bibliographic record
Abstract
Left ventricle non-compaction cardiomyopathy (LVNC) is an uncommon disorder characterized by the persistence of fetal myocardium of prominent trabecular meshwork, deep intertrabecular recesses, systolic dysfunction and left ventricular dilatation. It is thought to be caused by the arrest of normal endomyocardial morphogenesis. Here we present a case of a 27-year-old Caucasian female without past medical history who was presented to the emergency department because of syncope while she was working out. On further questioning, she relates that she has been having recurrent syncope for the last 9 years but she did not seek medical attention. Echocardiography and cardiac magnetic resonance imaging confirmed the diagnosis of LVNC and also showed a preserved ejection fraction. Implantable loop recorder showed recurrent non-sustained ventricular tachycardia. Although data were limited, an implantable cardioverter-defibrillator was prophylactically implanted because of the individual’s high sudden cardiac death risk.

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.
