Cardiac ablation does carry risks, which include:

  • Bleeding at the site where your catheter was inserted
  • Damage to your blood vessels where the catheter may have scraped as it traveled to your heart
  • Puncture of the heart
  • Damage to your heart's electrical system, which could worsen your arrhythmia and require a pacemaker to correct
  • Blood clots, which could lead to a heart attack or stroke
  • Narrowing of the veins that carry blood between your lungs and heart (pulmonary vein stenosis)
  • Damage to your kidneys from dye used during the procedure

Your risk of having these complications may increase if you have diabetes or kidney disease. You also have a greater risk of complications from ablation if you're 75 or older.
