Summary
Transcatheter aortic valve implantation (TAVI) via the transaortic (TAo) route offers an alternative access method. This article details the technical aspects of performing TAo-TAVI using specific prostheses and delivery systems.
Area of Science:
- Cardiovascular Medicine
- Interventional Cardiology
- Surgical Innovation
Background:
- Aortic stenosis is a significant condition requiring valve replacement.
- Transcatheter aortic valve implantation (TAVI) is a primary treatment for high-risk patients.
- Established TAVI access routes include transfemoral and transapical.
Purpose of the Study:
- To describe the technical aspects of performing transaortic TAVI (TAo-TAVI).
- To detail the use of Edwards Sapien prostheses with Ascendra delivery systems for TAo-TAVI.
Main Methods:
- Description of the transaortic access technique for TAVI.
- Utilization of Edwards Sapien and Sapien XT prostheses.
- Employment of Ascendra I and Ascendra II delivery systems.
Main Results:
- Successful performance of TAo-TAVI procedures.
- Detailed procedural steps for the transaortic approach are outlined.
- Experience with specific TAVI devices via the transaortic route is presented.
Conclusions:
- The transaortic approach is a feasible route for TAVI.
- Detailed technical understanding is crucial for successful TAo-TAVI.
- This method provides an alternative for patients unsuitable for other TAVI access routes.
