Successful aortic valve-sparing procedure for an aortic root aneurysm associated with a congenital defect of the right sinus of Valsalva—a case report
Bibliographic record
Abstract
Background: Aneurysm of the sinuses of Valsalva (ASV) is a rare but potentially lethal condition.Young patients with aortic root aneurysm and normal aortic valve are preferentially treated with a valve-sparing root replacement (VSRR).However, this option may not be feasible in the presence of an ASV.We herein describe a unique repair technique that allows ASV closure and subsequent VSRR.Case Description: A 50-year-old patient with a dilated aortic root was referred to our clinic.Upon examination of the aortic root, a localized disruption of the aortic wall between the annulus and the right coronary artery was identified.This finding jeopardized the feasibility of a valve-sparing procedure.A primary repair of the congenital aneurysm was attempted using a series of interrupted sutures.This successfully recreated the continuity between the valve annulus and the aortic wall.Reimplantation was then carried out in a standard fashion and the postoperative echocardiography showed good aortic valve and cardiac function.Alternatives to this technique include the Bentall procedure which does not require any continuity between the aortic annulus and the sinuses.However, it has been associated with a higher incidence of valve-related complications.Conclusions: Direct closure of an ASV can allow successful valve-sparing.It represents an attractive option in young patients with a repairable aortic valve.

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.
