Deep dives
Evolution of Aortic Stenosis Treatments
Aortic stenosis is the most common valve disease necessitating intervention in the UK, and its incidence is rising as the population ages. The introduction of Transcatheter Aortic Valve Implantation (TAVI) represents a significant advancement, providing an alternative to traditional surgical aortic valve replacement (SAVR) for many patients. While TAVI procedures have increased substantially over the last two decades, the rates of SAVR have remained relatively stable. Emerging research suggests the possibility of offering these treatments earlier, based on imaging studies indicating structural heart changes may occur before symptoms arise, potentially affecting long-term outcomes.
