What this trial studies

This observational study aims to assess the efficacy and safety of the Hydra transcatheter aortic heart valve series in patients with severe aortic stenosis over a one-year period following the transcatheter aortic valve implantation (TAVI) procedure. It will collect clinical, procedural, and follow-up data, including evaluations of coronary access post-implantation and the use of remote ambulatory continuous electrocardiogram monitoring for 72 hours after discharge. The study will involve multiple centers and will follow patients for clinical outcomes at 45 days and one year.

Who should consider this trial

Good fit: Ideal candidates include patients aged 18 and older with severe aortic stenosis who are eligible for transfemoral TAVI as determined by their local Heart Team.

Not a fit: Patients with contraindications to TAVI or those deemed unsuitable for the Hydra THV series will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve treatment outcomes for patients with severe aortic stenosis by providing insights into the safety and efficacy of the Hydra heart valve.

How similar studies have performed: Other studies have shown success with similar transcatheter heart valve approaches, indicating a promising avenue for treatment.
