Damage to the kidneys from contrast dye used during the procedureĭiscuss the risks and benefits of atrial fibrillation ablation with your health care provider to decide whether it's right for you.Ĭatheter insertion points for cardiac ablationĭuring cardiac ablation, catheters are passed through a vein in order to reach the heart.Narrowing of the veins that carry blood between the lungs and heart (pulmonary vein stenosis).Blood clots in the legs or lungs (venous thromboembolism).Slow heart rate that could require a pacemaker to correct.New or worsening irregular heartbeats (arrhythmias).Bleeding or infection at the site where the catheters were inserted.Possible atrial fibrillation ablation risks include: A health care provider may recommend this type of ablation if you have A-fib symptoms, including a fast, fluttering heartbeat, that hasn't improved with medication or other treatments. Since the AV node doesn't prevent all of these chaotic signals from entering the lower chambers, the heart beats faster and irregularly.Ītrial fibrillation ablation is done to reset the heart's rhythm. In atrial fibrillation, electrical signals fire from many locations in the upper chambers, causing them to beat chaotically. The signal then passes into the lower heart chambers, causing them to squeeze and pump out blood. The signal travels through the heart's upper chambers to the atrioventricular (AV) node. In a typical heart, a tiny group of cells at the sinus node sends out an electrical signal.
