Abstract

fetched live from OpenAlex

Objective: To study the implantation skill of aortic valve replacement with stentless porcine valve (SPV) and the early clinical results. Methods: Between Nov.1999 and Jun. 2000, the Toronto SPV valve was implanted in 12 patients (mean age 65 years). All patients were followed up at one month postoperation with doppler echocardiography.Results: There was one operative death. Echocardiography indicated that the blood flow across a Toronto SPV bioprothesis resembles that of a normal aortic valve. Conclusion: Toronto SPV valves provide excellent clinical results. It may enhance regression of left ventricular hypertrophy and restoration of normal ventricular function.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
