5. “I definitely have A-Flutter and possibly A-Fib as well. They want to do an A-Flutter-only ablation on me. Will that help me?”
Probably not. We now know that, in general, A-Flutter originates in the right Atrium, and Atrial Fibrillation originates in the Left Atrium.
A right atrium ablation for A-Flutter does little for A-Fib. If you have both A-Fib and A-Flutter, but only have and Flutter-only ablation of the right atrium, it’s estimated the success rate for curing A-Fib is only between 5% and 10%.1
You’re probably wasting your time and undergoing needless risk to do an A-Flutter-only ablation when you also have A-Fib. Some A-Flutter may originate in the left atrium, or the A-Flutter may mask A-Fib which may appear later after a successful A-Flutter ablation. As many as half of all patients ablated for A-Flutter may later develop A-Fib.
But what if you have Atrial Flutter only and don’t have A-Fib? A Flutter ablation in the right atrium is relatively simple and doesn’t take much time.
In my opinion, an A-Fib ablation in the left atrium should normally be done at the same time as a Flutter ablation.
