218. A new approach to the treatment of mitral regurgitation caused by mural leaflet pathologies
Bibliographic record
Abstract
To assess immediate postoperative outcomes of mitral valve reconstruction with MitroFix device (Biointegral Surgical, Mississauga, ON, Canada) in patients with extensive prolapse of the mural leaflet. Seventy-one patients undergoing mitral valve reconstruction for extensive prolapse of the mural leaflet between March 2007 and February 2010, were assessed before surgery with transthoracic (TTE) and transesophageal echocardiography (TEE). They were re-assessed intraoperatively in operating room with 2D and 3D TEE. None of the patients showed more than trivial regurgitation in the early postoperative period. Repair techniques of the mural leaflet of the mitral valve may be challenging in cases of extensive prolapse, damage caused by infective endocarditis and restrictive motion as seen in ischaemic cardiomyopathy. The MitroFix concept comprises of a D-shaped annuloplasty ring with a curved surface made of medical-grade polymer covered with porcine pericardium. The device mimics the mural leaflet in the closed position.

Full frame machine prediction
Teacher imitationNot 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.
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 source (direct Gemma or distilled Codex), not a consensus.
