Atrial fibrillation (AF) is frequent after any cardiac surgery, but evidence suggests it may have no significant impact on survival if sinus rhythm (SR) is effectively restored early after the onset of the arrhythmia. In contrast, management of preoperative AF is often overlooked during or after cardiac surgery despite several proposed protocols. This study sought to evaluate the impact of preoperative AF on mortality in patients undergoing isolated surgical aortic valve replacement (AVR).

术前房颤与接受外科主动脉瓣置换术的患者的长期死亡率相关

心房颤动 (AF) 在任何心脏手术后都很常见，但有证据表明，如果在心律失常发作后早期有效恢复窦性心律 (SR)，它可能对生存没有显着影响。相比之下，尽管提出了几种方案，但在心脏手术期间或之后经常忽视术前 AF 的管理。本研究旨在评估术前 AF 对接受单纯手术主动脉瓣置换术 (AVR) 的患者死亡率的影响。
