Evaluating the Hydra valve for severe aortic stenosis in Copenhagen

Prospective Observational Single-centre Study on the Efficacy and Safety of Hydra Transcatheter Aortic Valve

Observational Sahajanand Medical Technologies Limited · NCT06342635

This study is testing a new type of heart valve for people with severe aortic stenosis to see how well it works and if it causes any new heart rhythm problems after the procedure.

What this trial studies

This observational study aims to assess the efficacy and safety of the Hydra transcatheter aortic valve (THV) series in patients with severe aortic stenosis over a one-year period following the procedure. It will also investigate the impact of valve geometry on the occurrence of new conduction abnormalities by analyzing post-operative CT scans one month after the transcatheter aortic valve replacement. The study involves patients who are eligible for the TAVI procedure as determined by a local Heart Team evaluation.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18 years and older with severe aortic stenosis who are eligible for the TAVI procedure.

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 valve.

How similar studies have performed: While this study focuses on a specific valve series, similar studies evaluating transcatheter aortic valve replacements have shown promising results in improving patient outcomes.
