Study summary

Severe aortic stenosis is a common heart condition affecting elderly patients. Degeneration of the aortic valve (oneway valve between the heart and the aorta) causes high resistence to blood flow, resulting in strain on the heart and the potential for heart failure and death. Treatment of aortic stenosis has traditionally been with open heart surgery. A new procedure called transcatheter aortic valve implantation (TAVI) allows new aortic valves to be implanted through the femoral arteries, resulting in equivalent outcomes to open surgery with a more rapid recovery. Some complications remain present however, including the risk of debris released during the valve implantation being carried by the blood stream into the brain. This may lead to strokes and a loss of mental capacity. Devices that filter the blood stream and capture this debris have now been developed but are of uncertain benefit. We plan to investigate the brain function of patients who have been randomly assigned to the TAVI procedure with and without the use of filters to see if there are any cognitive benefits to the use of this technology.

Patients who are enrolled in the BHF PROTECT-TAVI trial will be invited to partcipate in this trial. They will have already been randomly assigned to TAVI with or without cerebral filter use. We will perform a series of bedside clinical tests (lasting \~40 minutes) involving questionnaires, pen \& paper and computer-based tasks. These will be performed both pre- and post-TAVI. There is no change to routine patient care. Data will be analysed with the assistance of trained neuropsychologists and will provide a valuable insight into the performance and role of the cerebral filter for TAVI patients in the future.

Study population

Patients will be selected from those undergoing Transcatheter Aortic Valve Implantation at the Royal Sussex County Hospital, Brighton, United Kingdom.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Randomised in the BHF PROTECT-TAVI trial (assessing stroke outcomes in TAVI with and without filter use).
  • Willing to provide for participation in this trial.

Exclusion criteria

Exclusion Criteria:

  • Participant has been excluded from use of the filter device due to anatomical or clinical .
  • Inadequate English skills.
  • Inability to complete assessment tasks due to visual or auditory impairment.
Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from May 2021 to primary completion in Jun 2022, 12 months.

Of 47 non-industry observational studies under Aortic Valve Disease, half reached primary completion within 49 months of starting (the median), counting those still running; a quarter within 23 and three quarters within 147. This study's 12 months is below that.

Counting every sponsor, half of 56 studies reached it within 49 months; a quarter within 23 and three quarters within 97.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Nov 7, 2023, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
