A Rare Complication of Transcatheter Aortic Valve Replacement: Right Ventricular Intramyocardial Hematoma
Bibliographic record
Abstract
Right ventricular (RV) intramyocardial hematoma is a rare yet potentially life-threatening complication associated with percutaneous coronary intervention (PCI), cardiac surgery, and catheter ablation. Here, we present a unique case of RV intramyocardial hematoma that developed within hours following transcatheter aortic valve replacement (TAVR). The patient experienced hemodynamic instability due to compression of the right ventricular outflow tract (RVOT). The clinical presentation and echocardiographic findings initially suggested tamponade, prompting urgent surgical exploration with redo-sternotomy. Intraoperative findings enabled the refinement of the diagnosis and led to a conservative management approach, resulting in a favorable outcome.

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.
