TL;DR: The long-term outcome of asymptomatic patients with severe AS was dismal when managed conservatively in this real-world analysis and might be substantially improved by an initial AVR strategy.

TL;DR: Increased BNP level was associated with a higher risk for AS-related adverse events in patients with asymptomatic severe AS with normal left ventricular ejection fraction who were not referred for AVR.

TL;DR: AHF complicating severe AS was associated with an extremely dismal prognosis, which could not be fully resolved by AVR, and careful management to avoid the development of AHF is crucial.

TL;DR: A large Japanese multicenter registry of consecutive patients with severe AS included a much higher proportion of women than men, with the female:male sex ratio increasing with age, and the 5-year mortality rate of women was lower than that of men.

TL;DR: Both non-cardiac factors (age, male, body mass index <22, diabetes, prior history of stroke, dialysis, anemia, and malignancy) and cardiac factors (atrial fibrillation, ejection fraction <68%, and the initial AVR strategy) were associated with non- Cardiac death.
