%X <B>BACKGROUND: </B>Recent developments in surgical devices, including left atrial appendage closure, have enabled surgeons to perform aggressive operations for atrial fibrillation (AF). However, the outcomes of AF surgery in emergent cases have not been extensively studied.<BR><B>OBJECTIVE: </B>The present study aimed to investigate the effectiveness of AF surgery in emergency surgery cases associated with cardiovascular events. We enrolled 18 patients who underwent various types of AF surgery due to emergencies, including acute aortic dissection (n = 6), acute myocardial infarction (n = 5), bleeding due to perforation from radiofrequency catheter ablation (n = 4), acute mitral regurgitation (n = 2), and cardiac tumor (n = 1). Four and ten patients underwent the full maze procedure and pulmonary vein isolation, respectively. Ganglionated plexi ablation was also performed in three patients as part of a combined procedure. The left atrial appendage was solely closed in four patients.<BR><B>RESULTS: </B>There was no surgical mortality or major adverse cardiac and cerebrovascular events in our patient series. The rates of freedom of recurrence of AF or atrial tachycardia at 1 and 3 years were 92.9% and 82.5%, respectively. After a mean follow-up period of 46.7 ± 25.8 months, no thromboembolism events were observed in the patients. Furthermore, no cardiovascular death was recorded.<BR><B>CONCLUSIONS: </B>The surgical procedures for AF are safe and effective in cases requiring emergency surgery.
