Fifteen-year experience in the surgical management of right atrial myxoma
Bibliographic record
Abstract
Objective: This study presents our experience with the clinical presentation, tumor characteristics, surgical management and post-operative outcomes of patients operated for right atrial myxoma.Methods: A retrospective analysis of all patients diagnosed with right atrial myxoma in our center from years 2000 to 2015 was conducted.All data were gathered from medical records following board approval.Twelve cases were identified, eight of which were female.Data is reported as frequencies, percentages, averages and ranges.Results: Clinical presentation proved very heterogeneous amongst our group.The most common finding was right-sided heart failure in 2 patients (17%).The average tumor size was 30mm and the most common attachment site was the inter-atrial septum.Myxomas were resected through median sternotomy or right thoracotomy.Post-operative morbidity includes dysrhythmias and tricuspid disease despite morphologically normal tricuspid structure in most cases.There was no perioperative mortality.Follow-up averaged 39 months and showed no recurrence.Conclusions: While surgical results for right atrial myxoma are satisfactory, its inconsistent presentation and rarity continue to pose a diagnostic challenge to clinicians who encounter it.Our data and review of literature identified right-sided heart failure, tricuspid regurgitation and pulmonary embolism as common findings in right atrial myxoma and lead us to suggest that clinicians consider it in their differential diagnosis in situations where such findings go unexplained.

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.
