New-Onset Postoperative Atrial Fibrillation and Long-Term Survival After Aortic Valve Replacement Surgery

This study provides evidence that new-onset post-AVR AF is significantly associated with increased long-term risk of mortality independent of the preoperative severity of disease. After controlling for a comprehensive array of risk factors associated with post-AVR adverse outcomes, risk of long-term mortality in patients who developed new-onset post-AVR AF was 48% higher than in patients without it.
