Risks

Cardiac ablation carries a risk of complications, including:

• Bleeding or infection 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 your heart
• Damage to your heart valves
• Damage to your heart's electrical system, which could worsen your arrhythmia and require a pacemaker to correct
• Blood clots in your legs or lungs (venous thromboembolism)
• Stroke or heart attack
• 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
• Death in rare cases

Discuss the risks and benefits of cardiac ablation with your doctor to understand if this procedure is right for you.
