Pulmonary vein ablation is a treatment for atrial fibrillation.
Pulmonary vein ablation is one option used to treat atrial fibrillation and may be most appropriate for patients who:
Have continued symptoms of atrial fibrillation, despite treatment with medications
Can not tolerate antiarrhythmic drugs, or have had complications from these drugs
Atrial fibrillation is an abnormal heart rhythm that originates in the top chambers of the heart.
With atrial fibrillation, the SA node does not direct the heart’s electrical rhythm. Instead, many different impulses rapidly fire at once, causing a very fast, chaotic rhythm in the atria. Because the electrical impulses are so fast and chaotic, the atria cannot contract and/or squeeze blood effectively into the ventricle.
During the procedure energy is delivered through the tip of the catheter to tissue that is targeted for ablation. The energy is applied in a circle around the connection of the left upper and lower pulmonary veins to the left atrium.
