Pheochromocytoma presenting as inverted Takotsubo cardiomyopathy
Bibliographic record
Abstract
The classical entity of Takotsubo cardiomyopathy is well established in the literature, but mechanisms explaining it remain unelucidated. Recently, the uncommon inverted Takotsubo type (sparing apical ballooning) has been more frequently described. We report the case of a 26-year-old man admitted with gastrointestinal symptoms, whose clinical presentation for a stress-related cardiomyopathy, which usually presents with cardiopulmonary symptoms, was rather atypical. The cardiac assessment including echocardiography and cardiac magnetic resonance imaging (MRI) demonstrated a dilated cardiomyopathy, whereas coronary angiography showed the absence of atherosclerotic disease. The abdominal computed tomography (CT) scan revealed a left adrenal mass, and elevated urinary catecholamine levels were highly suggestive of a pheochromocytoma. Prompt medical and surgical treatments were instituted. During the left adrenalectomy the patient suffered from brief electromechanical dissociation requiring aggressive resuscitation. Postoperative course was unremarkable. Reverse Takotsubo heart failure is a recently recognized syndrome and a systematic review of the literature of 10 cases of pheochromocytoma-induced inverted Takotsubo is presented in the present article.

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.
