About this study

Official title: Cognitive and Functional Outcomes Following Transcatheter Aortic Valve Implantation (TAVI): a Pilot Study

Narrowing of the aortic valve in the heart, known as severe aortic stenosis, can impede blood delivery and is associated with poor quality of life and death. In the elderly with considerable medical burden, a relatively new non-invasive valve replacement technique called Transcatheter Aortic Valve Implantation (TAVI) can be used instead of open-heart surgery. However, long term changes in cognition after TAVI remain unclear and previous studies have suggested an increased risk of cognitive decline in patients following the surgical procedure. In this pilot study, the investigators will characterize changes in cognition, physical capacity, overall quality of life and neuropsychiatric symptoms (depression and apathy) over 6 months after TAVI.

Read the detailed description

Cardiovascular disease including valvular heart disease, contributes to an estimated 36% of all deaths over the age of 70. In particular, severe aortic stenosis is the most common valvular heart disease in the elderly in the Western world and is associated with reduced quality of life and increased mortality. TAVI has been shown to improve survival, with an all-cause mortality at 1 year similar to surgical aortic valve replacement (SAVR) with favourable outcomes long-term including improved functional capacity and quality of life. Recent evidence from randomized controlled trials suggests an increased risk of neurological events (e.g. cognitive decline) up to 1 year after TAVI in comparison to both SAVR and medical treatment. Studies have shown no change in short-term memory, working memory, verbal learning, delayed recognition and verbal fluency 3 months after TAVI. In addition, patients with severe aortic stenosis have an increased risk of mortality and future health complications. This study will be an observational, prospective cohort pilot study to examine changes in cognitive performance and functional outcomes after TAVI. We propose to recruit 34 patients for this study. Cognitive performance will be measured using a standardized cognitive battery prior to TAVI and 6 months post-TAVI. Functional capacity, changes in neuropsychiatric symptoms and quality of life will also be assessed prior to TAVI and 6 months post-TAVI. We hypothesize there will a change in cognitive performance, functional capacity, mood outcomes and quality of life over 6 months after TAVI.

Questions about this trial

What is this clinical trial studying?

An observational study of Aortic Stenosis, run by Sunnybrook Health Sciences Centre at 1 site in Canada.

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 3 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: finished, as of the sponsor's last update on 17 Oct 2016. 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 Canada. 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.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Cognitive performance (time frame: 6 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 17 Oct 2016.
