Featured research - TAVI - Part 12
18 Nov 2025 – From PCR London Valves 2025
This session presents advanced research on transcatheter aortic valve implantation (TAVI), featuring an extensive 30-year in-vitro durability analysis of the Evolut self-expanding valve. It also covers predictive studies on valve-in-valve procedure volumes comparing Japan and the United States, insights into TAVI in patients with left ventricular...
TAVI in aortic regurgitation - Part 2
17 Nov 2025 – From PCR London Valves 2025
This session focuses on transcatheter aortic valve implantation in the setting of aortic regurgitation, a challenging clinical entity. It features novel techniques such as pump-assisted deployment and the use of deflectable self-expanding systems, as well as management of patients with prior valve-sparing aortic root surgery and...
Featured research - Aortic valve (Part 10)
26 Nov 2024 – From PCR London Valves 2024
Explore the latest research and insights in the field of aortic valve interventions through this featured research session. Discover cutting-edge studies on topics ranging from one-year outcomes after TAVI in different valve types to the impact of frailty and mobility on post-TAVI outcomes, and much more....
Aortic regurgitation - Part 3
21 Nov 2023 – From PCR London Valves 2023
Consult this session to gain valuable knowledge on approaches to address aortic regurgitation: uncover the clinical effectiveness of TAVR in managing aortic insufficiency associated with LVAD and delve into the comparison between echocardiography and magnetic resonance imaging for assessing device regurgitation in patients undergoing TAVI.
