Minimal-Access Left Ventricular Assist Device Explantation
Bibliographic record
Abstract
Patients on left ventricular assist device (LVAD) support can be successfully bridged to recovery. A novel explantation technique is reviewed. Six HeartMate II patients were successfully explanted off-pump through a combination of a left anterior minithoracotomy and a subxiphoid incision. A retrospective review of the institutional LVAD database was performed. The median LVAD support duration was 191 days (range, 69-307 days). There was no procedural or 30-day mortality associated with the LVAD explantation, and all patients are in New York Heart Association I to II at a median follow-up of 688 days (range, 127-1033 days). This procedure was associated with minimal blood transfusion and short intensive care unit stay (median, 1 day; range, 1-5 days) and hospitalization (median, 4.5 days; range, 3-19 days). One postexplant embolic cerebral infarct occurred. The HeartMate II LVAD can be safely explanted through a less conventional minimal-access approach.

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.
