Abstract

Background: Postoperative atrial fibrillation (POAF), a common complication of cardiac surgery, increases postoperative mortality, morbidity, and medical costs. POAF after coronary artery bypass grafting is well investigated; however, little is known about POAF after aortic valve replacement (AVR). This study aimed to investigate the efficacy of low-dose landiolol in preventing POAF after AVR. Methods: Thirty patients who underwent AVR were randomized into two groups, with or without administration of landiolol (Landiolol, N=15; Control, N=15). In Landiolol, continuous infusion of landiolol (3 µg/kg/min) was maintained for 48 h from admission to the intensive care unit. The occurrence of POAF during seven days after surgery, heart rate, blood pressure, cardiac index, and mixed venous oxygen saturation were compared between the two groups. Results: POAF occurred in one and seven patients in Landiolol (6.7%) and Control (46.7%), respectively, with significantly lower incidence in Landiolol than in Control (p=0.0352). The heart rate was significantly lower in Landiolol than in Control. No significant differences were observed in blood pressure, cardiac indices, and mixed venous hemoglobin oxygen between the two groups. Conclusions: The administration of low-dose landiolol following AVR significantly decreased the incidence of POAF without hemodynamic deterioration, suggesting that it may safely and effectively prevent POAF in patients undergoing AVR.
