Re-operative minimally invasive endoscopic mitral valve repair after partial atrioventricular canal repair
Bibliographic record
Abstract
Re-operation following previous congenital heart repair can be challenging. We present a 38-year-old female with a history of partial atrioventricular septal defect repair in infancy who developed severe mitral regurgitation due to a cleft anterior mitral leaflet. Given her anatomy and prior sternotomy, we performed a redo minimally invasive endoscopic mitral valve repair via right anterolateral minithoracotomy access. We meticulously closed the cleft using precise suture placement to restore leaflet integrity and function and performed an annuloplasty to reinforce the annulus and optimize leaflet coaptation. The minimally invasive approach minimized surgical trauma, while endoscopic visualization allowed for a precise and effective repair. This case highlights the feasibility of this approach in patients with complex congenital heart disease, offering a viable alternative to sternotomy with potential benefits for both short- and long-term outcomes.

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.
