Complicated: The answer to this is complicated. In electrophysiologists who are well trained catheter ablation to create pulmonary vein isolation is reasonably successful if that is the focus of your af. There are procedural risks (cardiac damage, arrhythmia, stroke, pulmonary vein stenosis and others) and the success is not always permanent (af can come back even if there was initial success.).
