New‐onset postoperative atrial fibrillation after heart surgery

New‐onset postoperative atrial fibrillation (poAF) complicates approximately 20‐60% of all cardiac surgical procedures and is associated with an increased periprocedural mortality and morbitity, prolonged hospital stay, increased costs, and worse long‐term survival. Unfortunately multiple advances in surgery and perioperative care over the last two decades have not led to a reduction in the incidence of poAF or associated complications in the daily clinical practice.
