Unusual presentation of an isolated unruptured aneurysm of the right sinus of Valsalva causing compression of the right ventricular outflow tract
Bibliographic record
Abstract
The aneurysm of the sinus of Valsalva is rare and usually asymptomatic unless rupture occurs. A 72-year-old man presented with exertional dyspnoea due to an unruptured aneurysm of the right sinus of Valsalva compressing the right ventricular outflow tract (Fig. 1 ). Successful elective surgical repair was undertaken (Fig. 2 ). Three-dimensional reconstruction of the computed tomographic scan demonstrating the aneurysm of the right sinus of Valsalva (ASV) with compression of the right ventricular (RV) outflow tract, under the pulmonary artery (PA). Intraoperative views and findings (A) showing the large aneurysm of the right sinus of Valsalva (ASV). The aneurysm appeared to have almost eroded into the right ventricle. Sutures have been placed into the right coronary cusp portion of the aortic valve annulus to reconstruct the proximal aortic root with a Dacron patch. (B) The Dacron patch was secured to the annulus and to the aorta. The right coronary artery will be re-implanted onto the Dacron patch.

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.
