Discuss:
1. Is the size of the heart normal?
 
 
2. Is the amount of epicardial fat normal?
 
 
3. [Jump to interactive video] Pause the video in anterior view. Draw out the coronary system.
 
 
4. [Jump to interactive video] Pause the video in posterior view. Draw out the coronary system.
 
 
5. [Jump to interactive video] Identify the main external anatomy (left ventricle, right ventricle, etc.)
 
 
6. Does the video show a possible cause of death?
 
 
7. What would be the significance of severe blockage in the left main stem vs. the left anterior descending coronary artery?
 
 
8. How much blockage is considered “clinicially significant”?
 
 
9. What causes coronary a. disease?
 
 
10. How long do you think this patient lived with this amount of blockage?
 
 
11. What are the indications for coronary artery bypass vs. coronary stent vs. balloon angioplasty?
 
 
12. Which treatment option would you select in a patient with this level disease? Or what else would you need to know to make a determination?
 
 
13. You are called to the scene of collapse as an emergency service provider; and informed by the patient’s partner that he had a severe blockage of the left anterior descending coronary artery? What specific resuscitation measures would you take for a patient with that history?
