Percutaneous Closure of Postinfarct Left Ventricular Pseudoaneurysm After Surgical Patch Dehiscence
Bibliographic record
Abstract
BACKGROUND: Left ventricular free wall rupture is a life-threatening mechanical complication of ST-segment elevation myocardial infarction. In patients with a timely diagnosis, emergent surgical patch repair is the cornerstone of management; re-rupture, surgical patch dehiscence, and left ventricular pseudoaneurysm (LVPA) are potential late complications after surgery. CASE SUMMARY: A 72-year-old man presented with NYHA functional class III dyspnea 4 months after surgical patch repair. We report, to our knowledge, the first case of successful percutaneous closure of LVPA resulting from surgical patch dehiscence. DISCUSSION: LVPA after surgical repair is a serious late complication. Multimodality imaging and careful case planning allowed for successful device closure with excellent clinical outcome. TAKE-HOME MESSAGES: Multimodality cardiac imaging is essential for accurate diagnosis and management of acute left ventricular free wall rupture and LVPA resulting from surgical patch dehiscence. Percutaneous closure of LVPA after surgical patch dehiscence is an effective and safe alternative to redo surgery.

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.
