You might be better off with an ablation. It is now considered to be the 'gold standard' for AF. What makes the difference, though, is the experience and skill of the EP. Find one who is busy, well regarded, and who does between six and ten ablations each week.

Just so you know, most EPs will want initially to tackle the pulmonary vein ostia where 80%+ of all AF originates. It's a reasonable first step, but while he/she is 'in there', a good EP will map the atrial wall and find other foci...if they exist...and ablate those. No common dog asking a patient to return in six months for another go at it when the risk is doubled, so a conscientious EP will do everything possible, barring complications or an already long ablation, at the one time.

Additionally, about 25% of all initial, or 'index', ablations fail. This is common across practicing EPs, although some do much better, notably Dr. Andrea Natale at Texas Cardiac Arrhythmia Institute in Austin. He travels to quite a few hospitals across the USA, but give his office a call if you can travel, and if you want the best.
