Applied Anatomy: Width of Sinuses
- The wider the sinus the more room there is to manipulate a catheter towards the coronary ostium.
- A narrow sinus would require a very acute angle for the catheter to be pointing towards the ostia for a non-selective coronary angiogram.

- A JR 4 can be used to engage left coronary in case of narrow sinus. And AR2 can be used to reach right coronary through valve frame in case of a wider sinus.
