SCIENTIFIC CHRONICLE Report from the 4th Vietnam Congress of Congenital and Structural Heart Disease (8-10 January 2014, Saigon, Vietnam) – “Fistulas from A to Z”
Bibliographic record
Abstract
on the morphology of the defect, he used various coils and implants made of nitinol wire mesh (type PDA, muscular VSD and others -American and Chinese production).In his material, no patient had either a heart rhythm disorder and cardiac conduction disease in the follow-up, or aortic valve regurgitation and tricuspid insufficiency, which may cause complications in such interventions.During the congress, a new pulmonary valve in the stent (Venus P Valve System), produced by Liftech, was presented.This very interesting product can be used in the case of a wider right ventricular outflow tract (RVOT) -also after correction of the Tetralogy of Fallot (TOF) with annular dilatation with patch, which is the most frequent in Poland.The implantation of the pulmonary valve is an outpatient procedure, whose main problem is the shortage of patients, who fully meet the criteria for the currently used "Melody" (maximum diameter 24 mm) and "Edwards" valves (maximum diameter 26 mm).Consultants of the venous valve are high quality experts such as Dr. Qureshi (UK) and Dr. Hijazi (US).With that valve, 10 procedures thus far have been performed in patients after surgical correction of TOF.For the first time in this congress, participants were directly acquainted with the method of implantation and valve's structure.It is made from pig pericardium and bound on a self-expanding nitinol stent, which does not require prestenting (as opposed to "Melody" and "Edwards" valves).Radial strength for this stent does not seem to be high, which indicates its potential application only in cases of dominant pulmonary regurgitation (frequent clinical problem).A number of procedures were performed live during the conference, usually by foreign experts.Within 3 days, 33 interventions, of any grade, were conducted.Procedures ranged from balloon pulmonary valvuloplasty (BPV) and balloon aortic valvuloplasty (BAV) to ASD closure, VSD closure and PDA closure, with different occluders for stent implantation in aortic coarctation, pulmonary artery and PDA, left atrial appendage closure etc.I was participating in effective BPV, performed in an infant (body mass 9.4 kg) with balloon catheter Valver produced by Balton Ltd.

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.
