Aortic Angulation Does Not Influence Outcomes in Contemporary Transcatheter Aortic Valve Replacement
Background: Initial experience in transcatheter aortic valve replacement (TAVR) has demonstrated that an aortic angulation (AA) greater than 48 degrees can reduce the likelihood of procedural success in high-risk patients receiving a self-expanding (SE) transcatheter heart valve (THV). It is not clear whether AA still impacts outcomes with contemporary THVs and deployment techniques.
