Smart materials have intrinsic properties that change in a controlled fashion in response to
external stimuli. Currently, the only smart materials with a significant clinical impact in …

Leaflet durability and costs restrict contemporary trans-catheter aortic valve replacement
(TAVR) largely to elderly patients in affluent countries. TAVR that are easily deployable …

Background There is a concern that resheathing/repositioning of transcatheter heart valves
during transcatheter aortic valve implantation (TAVI) may lead to an increased risk of …

Background No study has evaluated the impact of the additional manipulation demanded by
multiple resheathing (MR) in patients undergoing transcatheter aortic valve replacement …

Background The possibility to resheath some transcatheter heart valves (THV) facilitates the
optimization of self-expandable devices implantation. However, resheating manoeuvres …

The Evolut platform (Medtronic, Minneapolis, MN) and the Portico (Abbott, Abbott Park, IL)
are selfexpanding transcatheter heart valves (THVs) designed with recapturable and …

Background. Transcatheter aortic valve replacement (TAVR), widely used as an alternative
therapy in patients with severe aortic stenosis, is expected to be offered to low‐risk patents …

Background: The impact of nodular calcifications in left ventricular outlow tract (LVOT) and
aortic annulus on the procedural outcome of transcatheter aortic valve implantation (TAVI) …

Background In recent years, transcatheter aortic valve implantation (TAVI) without
predilation (direct TAVI) has become the preferred method for implanting TAVI prostheses …
