About this study

Official title: Multicenter Ambispective Study of Clinical Outcomes of the CoreValve™Evolut R™ 34mm System: All Comers Post-market Registry

With the introduction of the CoreValve™ Evolut R™ 34mm (Medtronic™) prosthesis, patients with severe symptomatic aortic stenosis (AS) and large aortic annulus have become eligible for transcatheter aortic valve implantation (TAVI). The aim of this study is to detect the number of TAVI candidates with large aortic annulus, and to evaluate the feasibility, efficacy, and safety of TAVI using the CoreValve™ Evolut R™ 34mm.

Read the detailed description

With the current transcatheter valves available in the market, is possible to cover a wide range of patients with diverse and complex anatomies. Nevertheless, there is a subgroup of patient with large aortic annulus (diameter > 27 mm), in whom the implant of a transcatheter valve is not possible because there is no valve suitable for such as aortic annulus size.

With the introduction of the CoreValveTM EvolutionTM R 34mm, patients with an aorttic annulus dimension up to 29 mm in diameter have become eligible for TAVI. However, there is a lack of information regarding the number of patient with AS and this particular anatomy of the aortic annulus. Italian and Dutch registries have reported a prevalence between 6.5 to 12.3% with large aortic annulus requiring the previous CoreValveTM 31mm. Yet, there is no reported data regarding this population of patients in Spain. Also, the clinical use of this larger prosthesis covers a wider range of aortic rings and may enchance the procedural challenges, such as a little margin for proper valve placement, more likelihood of interference with mitral valve function and damage to the cardiac conduction system during the prosthesis deployment.

So far, no studies regarding clinical experiences with the CoreValveTM EvolutionTM R 34mm have been published. The scarce information currently available with this new device may be distant from those found in its daily clinical use in non-selected patients. The results of this Spanish nationwide registry will help to answer a scientific need of information regarding acute procedural results and mid

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 19 Mar 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Spain. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03621709, which also lists 12 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
