In‐silico evaluation (computer simulated analysis in a virtual stroke model) has the potential to test and optimize large number of stent‐retriever design variations in a relatively time and cost‐effective manner. Further, new design concepts can be tested across multiple anatomical scenarios.

She was taken to the cath lab, where she was found to have 100% in-stent restenosis of the proximal LAD. Prompt cath to define the anatomy should be expedited. About 45 minutes after the second EKG, the patient was found in cardiac arrest. She was worked as a full code, and ROSC was achieved.
