Has anyone successfully cured atrial fibrillation?

Ablation&maze proced: Catheter ablation and surgical maze procedures can cure atrial fibrillation for many patients.

Define cured: Atrial fibrillation is a degenerative disease of the upper chamber which results in deposition of microscopic amounts of scar tissue, a generally irreversible process. However, certain procedures such as a surgical maze or catheter ablation can prevent patients from developing the rhythm of atrial fibrillation, or, barring that, the symptoms from the arrhythmia with up to ~70% success.
