  • Heart attack
  • Stroke
  • Injury to the catheterized artery
  • Irregular heart rhythms (arrhythmias)
  • Allergic reactions to the dye or medications used during the procedure
  • A tear in your heart or artery
  • Kidney damage
  • Excessive bleeding
  • Infection
  • Radiation exposure from the X-rays
