New-generation TAVI devices: description and specifications

EuroIntervention. 2014 Sep;10 Suppl U:U90-U100. doi: 10.4244/EIJV10SUA13.

Abstract

Transcatheter aortic valve implantation (TAVI) is an established treatment for inoperable patients or patients at high risk for surgery. Despite growing experience, issues remain associated with first-generation TAVI devices, including valve malpositioning, vascular complications, paravalvular regurgitation and conduction disorders. Several second-generation TAVI devices, aimed at addressing these issues, are CE marked or under evaluation for CE marking. The objective of this overview is to describe and illustrate the key design features of the second-generation devices that are entering contemporary clinical practice.
