People with AF sometimes have a procedure called an ablation to help get their heart back into a normal rhythm. However, this treatment doesn't always work. This study is looking at whether adding an extra step to the usual ablation-specifically treating another area of the heart called the left atrial (LA) posterior wall-can help people feel better overall, compared to just repeating the standard pulmonary vein isolation ablation procedure."}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years',
