ABSTRACT

Objective To assess the impact of atrial fibrillation (AF) on the early outcomes of patients underoin aortic valve replacement (AVR). Methods The clinical data of 961 adult patients who underwent AVR in Department of Cardiothoracic Surery, Chanhai Hospital between Jan. 2000 and Dec. 2011 were retrospectively analyzed. The patients with pre-operative AF were assined to AF roup (= 54) and the rest to non-AF roup (n = 907). Pre-, intra-, and postoperative findinswere compared to assess the impact of AF on early outcomes. Possible risk factors affectin the early mortality were identified usin loistic reression analysis. Results AF patients compared with non-AF patients had an elder age(P120 min were independent risk factors for early mortality. Conclusion AF has a neative impact on the early outcomes of patients underoin AVR. AF patients have hiher pos-operative early mortality and more related complications compared with non-AF patients.
