Koshy AN, Enyati A, Weinberg L, et al. - In patients undergoing liver transplantation (LT), researchers conducted this retrospective cohort study to evaluate a possible correlation of postoperative atrial fibrillation (POAF) with subsequent thromboembolic events. Between 2010 and 2018, consecutive adults undergoing LT were analyzed. POAF occurred in 47 (10.2%t) out of the 461 patients included at a median of 3 days after transplantation. Advanced age, postoperative sepsis, and left atrial enlargement were independent predictors of POAF. Twenty-one cases of stroke and systemic embolism occurred over a median follow-up of 4.9 (interquartile range, 2.9–7.2) years. An 8-fold increased risk of thromboembolic events is associated with POAF following LT, and risk stratification of these patients can be done via the CHA₂DS₂VASc score. Prospective studies are warranted in order to determine whether oral anticoagulants can reduce the risk of thromboembolism after LT.
