Rescue Balloon Aortic Valvuloplasty After Sutureless Aortic Valve Replacement for Severe Paravalvular Leak
Bibliographic record
Abstract
Sutureless aortic valve replacement (AVR) is a wide-spreading new technology that provides short clamping time and excellent hemodynamic outcomes. However, among its possible complications is the risk of paravalvular leak. We present the case of a 63-year-old woman who underwent minimally invasive right mini-thoracotomy AVR) with Perceval S sutureless valve (LivaNova, London, UK). Intraoperative transesophageal echocardiography revealed severe paravalvular leak with stent distortion. Rescue balloon valvuloplasty was performed through the right femoral artery, and resulted in the resolution of the paravalvular leak. This case illustrates the utility and feasibility of balloon valvuloplasty in trouble-shooting sutureless aortic valve stent distortion, thus avoiding a repeat aortic cross-clamp and valve replacement.

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.
