Peripheral embolisation and retrieval of an everolimus-eluting stent during intervention in a tortuous right coronary artery
Bibliographic record
Abstract
A 78 year-old female with dyslipidemia, diabetes, and hypertension as cardiovascular risk factors underwent percutaneous coronary intervention of tortuous, diffusely diseased right coronary artery (90% stenosis) due to chronic stable angina (Canadian Cardiovascular Society class III) despite guideline-directed medical treatment. After predilatation, a 2.75 × 44 mm Xience Expedition everolimus-eluting stent (Abbott, USA) was tracked, which failed and embolised to the right deep femoral artery during its pullback. It was successfully retrieved by an EN snare: 6–10 mm (Merit Medical, USA) by contralateral femoral approach. Lesion was further dilated and successfully stented using a GuideLiner mother–and-child catheter (Vascular Solutions Inc., USA) by deploying two overlapping 2.75 × 33, and 3 × 23 Xience Expedition drug-eluting stents distally and proximally respectively showing proper stent expansion with TIMI-3 coronary flow.This case highlights trackability issues and the importance of adequate lesion preparation before stent deployment in a tortuous vessel with diffuse disease, especially with a very long stent.

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.
