CTO PCI and routine PCI have similar complications, although they are more common in CTO PCI. These may include:
- bleeding at the puncture site (arm or groin)
- kidney damage (usually temporary)
- allergy to contrast dye or medications
- heart attack
- damage to the arteries or the heart itself
Specific risks of the procedure, possible hurdles that may be encountered, as well as potential benefits for each patient are carefully reviewed prior to the procedure and discussed with the patient. At any time before or during the procedure, if the team detects that the risk may outweigh the benefits, the procedure is interrupted or not even performed.
