 If the first ablation doesn't work and you repeat with AFib? Yes, you can do a second ablation. Sometimes you can end up with other kind of arrhythmias called scar flutters, which is a total different circuit because the chamber is so remodeled that just like it caused AFib, it can cause other arrhythmias, and we can go in and fix that. If somebody does not have a successful ablation because the atrium is so remodeled, again, remodeling is bad for your heart, not your house, but your heart.
