Coronary Surgery in Patients With Preexisting Chronic Atrial Fibrillation: Early and Midterm Clinical Outcome

Preexisting AF in patients undergoing coronary artery bypass graft surgery is not associated with increased in-hospital mortality and major morbidity; however, it is a risk factor for reduced 5-year survival. Spontaneous cardioversion to SR during surgery is transient in the majority of patients and is not associated with midterm survival benefit.
