Flow-Gradient Patterns in Severe Aortic Stenosis with Preserved Ejection Fraction: Clinical Characteristics and Predictors of Survival.

CONCLUSIONS: NF/LG severe AS with preserved EF exhibits favorable survival with medical management and impact of AVR on survival was neutral. LF/LG severe AS is characterized by a high prevalence of atrial fibrillation, heart failure and reduced survival, and AVR was associated with improved survival. These findings have implications for evaluation of AS severity and subsequent management.
