Primary Cardiac Tumors Operated on in Côte d’Ivoire: They Are Almost All Myxomas
Bibliographic record
Abstract
Objective: Through this surgical series, we present the epidemiological and anatomical-clinical aspects and the surgical results concerning patients operated on for a primary cardiac tumor at the Abidjan Heart Institute. Materials and Method: This is a retrospective descriptive study covering the period of January 1982 to December 2022, based on the medical records of patients operated on for a primary cardiac tumor at the Abidjan Heart Institute. Results: Twenty-seven (27) patients underwent surgery for a primary cardiac tumor, including 14 women and 13 men with a mean age of 41.5 years (range 19 - 76 years). The main circumstances of discovery were exertional dyspnea, palpitation and syncope or pseudo-syncope. The main site was the septal wall of the left atrium. The diagnosis of myxoma was confirmed by pathological examination of the surgical specimen in 96.3% (n = 24) of the patients and it was a malignant large cell immunoblastic lymphoma of the myocardium in 3.7% (n = 1) of the patients. The mean largest diameter was 46.1 mm. The postoperative course was marked by an ischaemic stroke (n = 1); recurrence of a left atrial myxoma 5 years after the first tumor removal (n = 1). Two cases of death were noted, one due to the evolution of immunoblastic large cell lymphoma and the other due to an extracorporeal circulation accident. Conclusion: Almost all primary cardiac tumors operated on in Abidjan are myxomas. The circumstances of the discovery of these cardiac tumors are multiple and varied but dominated by exertional dyspnea, palpitation and syncope. Whatever their histological type, primary cardiac tumors are serious affections, in view of the haemodynamic and rhythmic disorders they cause.

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; a candidate call from one teacher head, not a consensus.
