Donnellan E, Wazni O, Kanj M, et al. - Given the link between morbid obesity and unacceptable high recurrence rates after atrial fibrillation (AF) ablation—as well as the recent revelation that risk-factor modification plays a role in reducing arrhythmia recurrence post-ablation—researchers undertook a single-center observational cohort study to compare recurrence rates of arrhythmia in morbidly obese patients who underwent prior bariatric surgery (BS) with those of nonobese patients after AF ablation in addition to morbidly obese patients who did not undergo BS. They found a link between bariatric surgery and a reduction in arrhythmia recurrence post-ablation for AF in morbidly obese patients compared with those of nonobese patients. Experts recommended considering morbidly obese patients for BS prior to AF ablation.
