Coronary Angiogram
CORONARY ANGIOGRAM
(BARTS HEART CENTRE)
A coronary angiogram is a procedure that uses X-ray imaging to see your heart's blood vessels. The test is generally done to see if there's a restriction in blood flow going to the heart. Coronary angiograms are part of a general group of procedures known as heart (cardiac) catheterisations
Procedure Equipment list:
- ANGIO-pack (KIMAL)
- Spike for saline bag
- 2 chloraprep
- 500ml NSS (sterile bag)
- Tegaderm dressing (to secure radial sheath)
- 6F Terumo radial sheath (Radial Approach) or 6F Cordis femoral sheath (Femoral approach)
- May use 5F catheters and 5F sheath if patient have small radial artery, female, or small male)
For IV drug line
- 500 mL saline bag
- Extension line (long)
- 3-way tap
- 20mL luerlock syringe
- 2ml or 5 ml luerlock syringe (labeled, for midazolam)
- blunt needle for aspirating drugs
- giving set
Diagnostic Catheters:
LCA (for left coronaries)
- 6F JL 3.5 catheter if radial
- 6F JL4 if femoral
- Others : JL 3,5,6 AR, MPA
RCA (for right coronaries)
- 6F JR4 catheter
- Others: WR, AL1,2, AR 1,2,3, MP
Single catheter technique: 5F TIG (for RCA and LCA)
If tortous vessel or if there’s spasm:
- 0.35 Terumo glide wire 150cm
- 0.35 Exchange wire 260cm
- 0.014 BMW wire
Medications:
- Lidocaine 1% 5ml amp if radial (20ml if femoral)
- Heparin 10,000iu/10mL
- 1 amp Isosorbide Dinitrate 10mg/10ml (Dilution: ISDN 2mg/2mL add with 8mL NSS to make 2mg/10mL or 200mcg/mL dilution)
- 1 amp Verapamil 2.5mg/2ml (Dilution: Verapamil 2.5mg/mL add with 4mL NSS to make 2.5mg/5mL)
- Optional: Midazolam 1mg/mL or Diazemuls 10mg/2ml
If taking aortogram or femoral angiogram
- 6F pigtail catheter
- High pressure tubing
- High pressure Contrast syringe
- High power injector
- Forcep (for tapping tubes to remove air and secure tube connections)
Closure devices:
- Angioseal (6F or 8F) for femoral access
- TR band or Helix (regular or large) for radial access
PROCEDURE STEPS
RADIAL APPROACH:
Operator injects 2-3 mL of Lidociane 1% subcutaneously
Inserts the sheath using Seldinger Technique
Aspirates blood from sheath to confirm patency of the puncture
Verapamil 2.5mg/5mL through the sheath (spasm prevention)
Then introduce catheter with guidewire (JR4 first for RRA, JL4 for RFA)
For RCA:
LAO 30
LAO 20 CRAN 20 / PA CRAN 30
RAO 30
For LCA:
PA CAUDAL 40
LAO 40 CAUDAL 40
LAO 10 CRAN 40
RAO 40 CRAN 40
RAO 30 CAUD 30
