Abstract

fetched live from OpenAlex

BACKGROUND : The St. Jude Medical Trifecta TM valve is a newly designed stented pericardial bioprosthesis, intended for implantation in the aortic position.It consists of a titanium stent with externally mounted pericardial leaflets.Its unique design maximizes hemodynamic and valve performance.In this presentation, the early clinical experience with this advanced biological valve will be discussed. METHOD and RESULTS: From August, 2007 to June, 2009, 203 subjects who met the eligibility criteria had Trifecta TM valves implanted as part of the FDA IDE study in seven Canadian centres.Prospective clinical and! or echo data were collected pre, peri" operatively, at discharge, 6 month, 12 month, and annually up to approximately 4 years.The mean age of patients was 73±8 with 64% male.Isolated AVR and AVR+CABG were performed in 45% and 46% of cases respectively.There was no 30" day mortality.One valve related death due to intracranial bleed occurred 116 days post implant.Thirteen(9 early and 4 late) neurologic events, 21(16 early and 5 late)major bleeding events, two late endocarditis, and three late deaths (non" valve related) were reported.No structural valve deterioration has been reported.Significant aortic insufficiency was reported in two subjects, one subject at 6 months had severe central and paravalvular AI and one subject at 1 year had severe paravalvular insufficiency.The hemodynamic results were as below :CONCLUSIONS : The SJM Trifecta TM aortic biological valve demonstrates excellent early clinical results.Its unique design provides superb hemodynamic performance.On" going long" term study is being carried out to access its durability and performance.

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.
