Aortic Valve Disease Clinical Trial
Official title:
Randomized Comparison of Repositionable and Balloon-Expandable Prostheses in Patients Undergoing Trans-catheter Aortic Valve Implantation
There are different aortic valve prosthesis used for treatment of aortic valve disease through catheter-based procedures. The current study aims to compare two different aortic valve prosthesis regarding their outcomes at 30-day and 2-year follow-up.
Important improvements in aortic valve prostheses technology has been made aiming comparable
performance of these prosthesis to surgical valve ones.
The experience with the early generation of aortic valve prostheses revealed some important
differences regarding the incidence of paravalvular leakage, need for pacemaker or valve
thrombosis among them. Currently the new generations of valve prostheses such as Sapien 3
balloon-expandable valve and Lotus, repositionable valve are the most frequently used
devices. There are registry data about the clinical performance of these valve types but a
randomized comparison is missing.
