Forma de presentación y evolución del ventrículo derecho bicameral
Bibliographic record
Abstract
INTRODUCTION: The double-chambered right ventricle (DCRV) is an uncommon congenital heart disease; it represents the 0,5% of these congenital cardiopathies. OBJECTIVE: To describe the clinical and echocardiographic characteristics of a series of 11 patients. METHODS: Eleven patients with DCRV were studied. A complete medical history, chest radiograph, electrocardiogram, and transthoracic echocardiography were performed. RESULTS: The median age of studied patients was 10 years. The 36.45% of cases were asymptomatic and the diagnosis was made by echocardiography. Other cases had weakness during food in the lactancy stage and worsening of NYHA functional class in older children. The echocardiogram showed double-chambered right by a muscular band in all studied patients. The most frequent associated anomalies were: ventricular septal defect, patent foramen ovale, subvalvular aortic stenosis, and Fallot's Tetralogy. Seven patients went to surgical treatment and now 6 of them are in NYHA functional class i. CONCLUSIONS: This paper has a special importance, because is the biggest series of patients with double-chambered right ventricle in Mexico and the results are comparable to the studies reported in the literature. The worsening of the NYHA functional class was the predominate symptom. The clinical manifestations can be presented from the lactancy to adulthood and the degree of obstruction could have a progressive character. The echocardiography is the method of choice in the diagnosis of these patients. The 91% of patients with DCRV who went to surgical treatment had excellent hemodynamic and functional results in the mid-follow-up.

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.
