Abstract

fetched live from OpenAlex

Background: Structural heart procedures performed under fluoroscopy and transesophageal echocardiography guidance require the expertise of an interventional echocardiographer in the heart team. Due to the proximity with the radiation source, the physician might be exposed to high radiation doses. This study aims to assess the interventional echocardiographer radioprotection by means of a dedicated cabin and evaluate its ergonomic characteristics. Methods: This is an observational nonrandomized study comparing cumulative radiation exposure between a control arm, consisting of a standard lead glass panel, and the experimental arm using the dedicated radioprotective Echosafe cabin. All structural heart procedures requiring transesophageal echocardiography between July 2021 and April 2022 were included. Cumulative radiation exposure of the interventional echocardiographer was collected by the body part and the satisfaction of the heart team with the cabin was assessed with a questionnaire. Results: = 0.94). The use of the cabin resulted in a numerically lower cumulative radiation dose to each body part. The mean overall reduction in radiation dose was estimated to be between 56 and 78% with the cabin. The most frequent negative aspects reported by the cabin users included difficulty moving the transesophageal echocardiography probe and the physical burden associated with initial installation. Conclusions: This preliminary study suggests that radioprotection of the interventional echocardiographer can be increased during structural procedures by using a dedicated cabin. Further studies with larger sample sizes and different design will be needed to confirm the reduction in irradiation of the echocardiographer.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
