Novel self‐expanding ALLEGRA transcatheter aortic valve for native aortic stenosis and degenerated bioprosthesis

Objectives To investigate the safety and efficacy of the ALLEGRA valve in routine use. Background The ALLEGRA aortic valve is a self‐expanding transcatheter heart valve (THV) with bovine pericardial tissue and was CE approved in March 2017. Its unique design was developed to provide low prosthesis gradients. Methods We analyzed patients receiving an ALLEGRA THV between May 2017 and March 2021 at our center for treatment of aortic valve stenosis...
