Why the study?
Current guidelines mainly recommend intervention in symptomatic aortic stenosis and evidence in asymptomatic patients is poor, but advances in procedural safety suggest earlier intervention may be indicated.
Does early aortic valve replacement reduce mortality in asymptomatic patients with severe aortic stenosis compared to conservative management?
Does early aortic valve replacement reduce mortality in asymptomatic patients with severe aortic stenosis compared to conservative management?
While current guidelines recommend watchful waiting for asymptomatic severe aortic stenosis, emerging observational evidence suggests early intervention may improve survival, highlighting the need for ongoing randomized trials.

Should not yet change watchful waiting for asymptomatic severe AS; leaves open early AVR benefit in select high-risk patients pending RCTs.
Aortic stenosis is a very common disease. Current guidelines recommend intervention mainly in symptomatic patients; aortic valve replacement can be considered in asymptomatic patients under specific conditions, but the evidence supporting these indications is poor. Continuous advances in both surgical and percutaneous techniques have substantially decreased rates of perioperative complications and mortality; with this in mind, many authors suggest that earlier intervention in patients with severe aortic stenosis, when they are still asymptomatic, may be indicated. This paper summarises what is known about the natural history of severe aortic stenosis and the scientific evidence available about the optimal timing for aortic valve replacement.
