Prognostic importance of atrial fibrillation in asymptomatic aortic stenosis: The Simvastatin and Ezetimibe in Aortic Stenosis study
Conclusion: Rate of AF is moderate in asymptomatic AS. Longstanding but not episodic AF was, independently predictive of increased risk of heart failure and non-hemorrhagic stroke. New-onset AF was associated with cardiac decompensation.
