Second-generation TAVI devices are designed to address the limitations of first-generation devices, including valve malpositioning, vascular complications, and paravalvular regurgitation.
This review provides a descriptive overview of the design features of second-generation TAVI devices aimed at reducing complications seen with earlier generations.
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.
Tchétché et al. (Mon,) conducted a review in Inoperable or high surgical risk patients requiring aortic valve replacement. Second-generation TAVI devices was evaluated. Second-generation TAVI devices are designed to address the limitations of first-generation devices, including valve malpositioning, vascular complications, and paravalvular regurgitation.
