Abstract

fetched live from OpenAlex

This article describes features and functioning of left-ventricular assist devices (LVAD). LVADs are the fastest-growing category of mechanical heart devices and are the only category of mechanical heart-assist devices to be approved in the United States, Canada, and Europe as a commercially available treatment. The current generation of LVADs and implantable artificial hearts represent a major technological step. However, by all accounts, these devices have a long way to go before they are as mechanically sound and user-friendly as they need to be to be widely accepted as a destination therapy for more than just the sickest of the sick. Thoratec Corp., Pleasanton, CA, has received Food and Drug Administration approval of its HeartMate SnapVE LVAD and an updated model, the HeartMateXVE, for use as a long-term, permanent treatment for end-stage congestive heart failure patients who don't qualify for heart transplantation and have a life expectancy of less than two years. These devices, the best known of which is the Abiocor, from AbioMed of Danvers, Massachusetts, are still considered experimental.

Full frame distilled prediction

Teacher imitation

Not 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.
