At present TAVR is a valid alternative to treat different risk groups of patients with severe aortic stenosis. Among the different valves, there are two types, the self-expanding (SEV) and the balloon expandable (BEV) valves, that are the most implanted and the most researched by randomized studies across different risk groups. There are different generations…
EuroPCR 2022 | LYTEN Trial: V-in-V in Small Annuli
TAVR is a valid alternative to treat failed surgical bioprosthetic valves, but one of its biggest challenges is patients with a small annulus. When using self-expanding valves, supra-annular implantation is recommended. However, at present, we only have retrospective, observational studies, not large enough. The LYTEN Trial is a randomized study in patients presenting failed bioprosthetic…
Are Self-Expandable Valves a Valid Option in Bicuspids?
Bicuspid Aortic Valves (VAV) are challenging for TAVR given its anatomical characteristics and the important presence of calcification. However, current data are promising. Even though traditionally excluded from the larger randomized studies, self-expandable valves appear to have similar evolution to tricuspid aortic valves (TAV) with severe stenosis. Researchers looked at the Low-Risk Bicuspid Study and…
Are Expandable-Balloon Valves an Option for the Bicuspid Valve in Low-Risk Patients?
Bicuspid aortic valve malformation is the most frequent cardiac malformation (about 1%), and a significant percentage of these cases generate severe aortic stenosis. As we know, transcatheter aortic valve replacement (TAVR) has been developed for tricuspid valves, which are studied in the most important randomized trials for high-, medium-, and low-risk patients. While current information…
Is Cusp Overlapping Projection the New Self-Expandable Valve Implantation Technique?
In Europe and the US, aortic stenosis is the most frequent cause of valve intervention, both surgical and percutaneous, and, as we all know, TAVR has made great progress in this regard. However, this technique has an Achilles heel when it comes to self-expandable valves: definite pacemaker implantation rate is 3 to 4 times higher…
