Abstract
The retroesophageal right subclavian artery (ROSRA; arteria lusoria) is one of the anatomical abnormalities encountered at innominate-arch junction during transradial catheterization by right route. Here, we report a case of a 49-year old female who presented with chronic stable angina (Canadian Cardiovascular Society class-III) despite guideline directed medical treatment. Coronary arteries were cannulated with difficulty showing critical lesion of proximal left anterior descending artery (LAD). During angiography, diagnostic catheter has a peculiar cobra loop in the ascending aorta. As the left subclavian artery also has critical lesion at the proximal part, percutaneous coronary intervention of proximal LAD artery was successfully performed with 3.5×23 mm Xience Prime Everolimus eluting stent (Abott, USA) through right femoral route. Multi detector computed tomography (MDCT) contrast aortography showed the origin of the right subclavian artery in the right posterior side of the horizontal aorta with a tortuous course, proximal stenosis of left subclavian artery (LSC), and a bicarotid truncus. This abnormality can be easily detected by angiographic visualization, in the anteroposterior projection, of the angle of the catheter when it engages the ascending aorta, and by manual angiography at the ostium of the right subclavian artery. In such a case, selective catheterization of both coronary arteries may be very difficult, time consuming, and require more catheters. In such cases, one should not be hesitant to switch to transfemoral route if left radial route cannot be utilised.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot 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.
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; both teacher heads agree on what is shown here.
