Only the transcripts of the films in this library, and the text of the slides shown in them. Every film is a Calcium Masterclass session recorded with practising interventional cardiologists. Nothing else is used: no internet search, no general medical knowledge, no other documents.

• Your question is matched against every passage spoken across the films, and the text of every slide shown in them.
• If nothing is close enough, the site says the library doesn't cover it and writes nothing.
• Otherwise a short summary is written from up to eight matching passages. Every sentence has to cite the passage it came from, or it is removed.
• If too little survives that check, no summary is shown, only the passages themselves.

The summary is labelled as written by AI. Beside it, each passage appears word for word with the film it came from, and plays from the moment it was said. Play all runs them back to back.

It doesn't give advice about individual patients, and it can't go beyond what was said on camera. A short answer, or none, means the films don't cover the question.

Anything on screen can be traced to a named clinician in an approved film, so nothing appears here that hasn't already been through review.
