Hydra Single-centre Experience - Copenhagen, Denmark
March 28, 2024 updated by: Sahajanand Medical Technologies Limited
Prospective Observational Single-centre Study on the Efficacy and Safety of Hydra Transcatheter Aortic Valve
The present study aims to evaluate the efficacy and safety of TAVI using the Hydra transcatheter aortic valve (THV) series, in patients with severe aortic stenosis up to 1-year after the procedure.
Additionally, the study will assess the role of geometry in the development of new conduction abnormalities based on the analysis of post-operative CT scan at 1-month in patients who had undergone transcatheter aortic valve replacement with a self-expanding Hydra THV series.
