By Mayo Clinic staffCardiac 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.
