Successful Closure of a Ventricular Septal Defect Using a Novel Non-Prosthesis Touching Technique Following Mechanical Aortic Valve Replacement
Bibliographic record
Abstract
Percutaneous intervention is preferred over reoperation for the treatment of iatrogenic membranous ventricular septal defects (VSDs). During the standard percutaneous procedure, an arterio-venous loop is used for occluder deployment, entailing the risk of device impingement on the prosthetic aortic valve, which may cause serious complications or even death. In this report, we describe a novel non-prosthesis touching procedure for the closure of a VSD in a patient with prior aortic valve replacement. The unique feature of this technique is the use of an apex-venous loop for occluder deployment, which prevents the device impingement on the prosthetic valve, thus avoiding difficulties, lengthy operation and serious complications associated with the standard procedure. Immediate and 1-year follow-up results showed that the VSD was successfully closed and no serious complications were observed.

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.
