About this study

Official title: Single-center Randomized Controlled Trial of Cardiac Function After Minimally Invasive Aortic Valve Implantation (CMILE)

This is a single-center, open-label, randomized controlled trial. Patients scheduled for aortic valve replacement (AVR) at Karolinska University Hospital in Stockholm, Sweden will be eligible. Forty patients will be randomly assigned to either minimally invasive (20 patients) or conventional AVR (20 patients). CE-marked and FDA-approved mechanical and bioprosthetic aortic valves (conventional stented or sutureless bioprostheses) will be implanted. Transthoracic echocardiography will be performed before surgery, and at day 1, 4, and 40. Echocardiographic parameters as well as preoperative clinical characteristics and postoperative clinical outcomes will be registered. Routine blood sampling will be performed pre- and postoperatively. All available data will be collected prospectively. Informed consent will be obtained from patients meeting the inclusion criteria before the initiation of any study-specific procedures.

Questions about this trial

What is this clinical trial studying?

A study testing Minimally invasive aortic valve replacement and Conventional aortic valve replacement in people with Aortic Valve Stenosis and Heart Valve Diseases, run by Karolinska University Hospital at 1 site in Sweden.

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 4 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 4 Aug 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 Sweden. 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?

Tricuspid Annular Peak Systolic Excursion (TAPSE) (time frame: Preoperatively and postoperatively at day 4 and 40). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01972555, which also lists 1 linked publication.

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 4 Aug 2016; AzTrials last refreshed its copy on 31 Oct 2026.
