Abstract

fetched live from OpenAlex

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.

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.

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.
