Agreed. The subtitle "Catheter navigates autonomously inside hearts in preclinical tests" would be far more accurate and less click baity.

Yes, the submitted title ("Autonomous Driving Inside the Heart") broke the site guidlines, which ask "Please use the original title, unless it is misleading or linkbait; don't editorialize." In this case, the subtitle is best, so we'll use that above. It looks like a good submission otherwise!
