When the Tumor Leaves but the Damage Lingers: A Case of Delayed Cardiomyopathy Recovery Post-Paraganglioma Resection
Bibliographic record
Abstract
Catecholamine-induced cardiomyopathy secondary to paraganglioma is a rare and potentially reversible condition. However, the course of recovery post-resection remains variable and may be delayed despite biochemical cure. We present the case of a 47-year-old male with biopsy-confirmed extra-adrenal paraganglioma who developed acute decompensated heart failure due to catecholamine-induced cardiomyopathy (left ventricular ejection fraction (LVEF) 30-35%) and multiorgan dysfunction. Despite successful surgical resection, his LVEF remained reduced postoperatively, and he was discharged on heart failure therapy and a wearable cardioverter defibrillator. A follow-up echocardiogram showed improvement in LVEF to 45% 2 weeks later, but his blood pressure remained poorly controlled despite adherence to a multi-drug regimen and lifestyle measures. He was readmitted with a transient ischemic attack (TIA) shortly after surgery. This case illustrates the variable recovery trajectory in paraganglioma-induced cardiomyopathy and highlights persistent cardiovascular risks, including resistant hypertension and cerebrovascular events despite biochemical cure. It emphasizes the importance of ongoing cardiac surveillance and multidisciplinary management, particularly in patients facing socioeconomic barriers to follow-up care.

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.
