<i>Cor triatriatum sinister</i> with left superior vena cava, unroofed coronary syndrome and valvular pulmonary stenosis
Bibliographic record
Abstract
A 25-year-old woman with a history of recent dyspnea and palpitation was admitted to our center.Transthoracic echocardiography (TTE) showed an echogenic and septal muscular ridge along the left atrium which were indicative of cor triatriatum sinister (CTS).Further evaluation with transesophageal echocardiography (TEE) showed that a lower chamber of divided left atrium receiving lower right inferior pulmonary vein, mitral valve, left superior vena cava (LSVC) and unroofed coronary sinus (CS).Also, the lower chamber had an unrestrictive communication with the right atrium.The upper accessory chamber receiving one left and one right upper pulmonary vein and communicated with the right atrium by a small atrial septal defect (ASD).However, upper and lower pulmonary venous systems separated directly from each other by a muscular ridge without the presence of any window or hole to allows blood flow between these two accessory chambers.Although the absence of septum associated with the presence of LSVC and unroofed CS makes our case a unique or very rare type of this complex anomaly in an adult case.In our case, surgical removal of dividing muscular membrane with redirection of LSVC and unroofed CS to the right atrium are warranted.

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.
