System Specifications C7/ILUMIEN C8 Clinical

Impact

Frame rate (frames per second)

100 fps 180 fps Higher frame rate = faster pullback

Pullback speeds

10, 20, 25 mm/sec

18, 36 mm/sec

Faster speed minimizes contrast required for longer

pullback

Pullback length 54 mm 75 mm

~90% of total lesions will occur in the proximal 50 mm of the left arterial

system. In the RCA, 80% of lesions are within 75 mm of the

ostium. Ref: Lesion locations within Arteries; J Am Coll Cardiol, 2005; 45:1186-1192

PULLBACK PREPARATION – PURGE THE CATHETER

• If blood enters the catheter lumen, purge with the attached 3 cc contrast syringe.

Blood in catheter lumen Purged catheter lumen

27

PREPARATION OF INJECTION

Recommended Settings:• Injection by hand

• Left coronary, Right coronary arteries: (16----20) ml ;

• We can use 12-20 ml syring In your Cath. (Depend on operator)

• When the operator is ready to inject contrast, click the “Enable Pullback ” button.

• Ask the Physician to inject, 3 sec from the injection and when the image is clear press ”Start Pullback”

PULLBACK PREPARATION – PUFF INTO THE VESSEL

• During live scan, puff with the contrast injector to determine guiding catheter position for optimal image clarity.
