Atrial fibrillation ablation

Risks

Possible atrial fibrillation ablation risks include:

  • Bleeding or infection at the site where the catheters were inserted
  • Blood vessel damage
  • Heart valve damage
  • New or worsening arrhythmia
  • Slow heart rate that could 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 atrial fibrillation ablation with your doctor to decide whether it's right for you.
