The study findings show the benefit of catheter ablation extends beyond improving quality of life for adults with atrial fibrillation. If successful, ablation improves life span, says lead study author Hamid Ghanbari, M.D., M.P.H., an electrophysiologist at the U-M Cardiovascular Center.
What is life expectancy after an ablation?
After a single ablation procedure, arrhythmia-free survival rates were 40%, 37%, and 29% at one, two, and five years. Most recurrences occurred within the first six months, while arrhythmias recurred in 10 of 36 patients who maintained sinus rhythm for at least one year.
Does ablation damage the heart?
Possible cardiac ablation risks include: Bleeding or infection at the site where the catheter was inserted. Blood vessel damage. Heart valve damage.
Which antiarrhythmic drug has the fewest side effects?
Dronedarone was the best tolerated of the antiarrhythmic drugs, with the lowest rates of severe adverse events and a significant reduction in the risk of stroke. It is our practice to use propafenone, flecainide, sotalol, and dronedarone as first-line therapies in patients without structural heart disease (Table 4).
