Outcomes of lung transplant recipients with preoperative atrial fibrillation

Abstract

Background Preoperative atrial fibrillation is associated with poor outcomes after cardiac surgery, but its effect on lung transplantation outcomes remains unknown. Methods We retrospectively reviewed the charts of 235 patients who underwent lung transplantation in our institution from 2013 to 2015, analyzing demographics, length of stay, survival, readmissions, and cardiac events. Mean recipient age was 59 ± 11 years, and 142 (60.4%) were men. Patients were grouped according to pre-transplantation atrial fibrillation status (atrial fibrillation/no atrial fibrillation). Results The atrial fibrillation group ( n = 38; 16.2%) was significantly older with a longer ischemic time, more postoperative atrial arrhythmias (73.7% vs. 20.8%, p = 0.01), and a longer median postoperative length of stay (16 vs. 13 days, p = 0.02). The median total hospital stay in the first postoperative year was also higher in the atrial fibrillation group (27 vs. 21 days, p = 0.25). Short-term survival and survival during follow-up did not differ significantly between groups. Conclusions Lung transplant recipients with preoperative atrial fibrillation are at increased risk of adverse cardiovascular outcomes and longer hospital stay. Preoperative atrial fibrillation may portend adverse events after lung transplantation.
