RisksBy Mayo Clinic staff
As with most procedures done on your heart and blood vessels, cardiac catheterization has some risks. Major complications are rare, though.
Risks of cardiac catheterization are:
- Heart attack
- Damage to the artery where the catheter was inserted that may require medical attention (pseudoaneurysm)
- Irregular heart rhythms (arrhythmias)
- Allergic reactions to the dye or medication
- Tearing the tissue of your heart or artery
- Kidney damage
- Blood clots
If you are either pregnant or planning to become pregnant, tell your doctor before having cardiac catheterization performed.
