About this study

Official title: Association Between Surgical Aortic Valve Replacement and Long-term Outcomes in 50 to 65-year-olds: Results of the AUTHEARTVISIT Study

The goal of this observational study o is to compare outcomes after either biological or mechanical aortic valve replacement. The main question it aims to answer:

Is survival better after mechanical aortic valve replacement compared to biological aortic valve replacement? Are there less complications and reoperations after mechanical aortic valve replacement compared to biological aortic valve replacement? We perform a retrospective Data Collection of anonymized Austrian health insurance data.

Read the detailed description

Objectives: In recent years, age recommendations for the utilization of biological prostheses rather than mechanical prostheses for surgical aortic valve replacement (sAVR) have been significantly reduced. This study evaluated survival rates, major adverse cardiac events (MACEs), and reoperation risks following surgical (sM-AVR) and biological (sB-AVR) AVR, with the aim of providing data to inform optimal prosthesis selection for middle-aged patients between 50 and 65 years.

Methods: A population-based cohort study was conducted using data from the Austrian Health System from 2010 to 2020. Patients undergoing isolated sAVR (n=3761) were categorized into sM-AVR (n=1018) and sB-AVR (n=2743) groups. Propensity score matching (PSM) was applied to balance covariates. The primary endpoint was all-cause mortality. The secondary endpoints included MACEs, reoperation, stroke, bleeding, and post-reoperation survival. Outcomes were assessed using Cox regression and Kaplan-Meier analyses.

Questions about this trial

What is this clinical trial studying?

An observational study of Aortic Valve Replacement, run by Medical University of Vienna at 1 site in Austria.

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 2 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 20 Jan 2025. 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 Austria. 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?

Survival (time frame: up to 12 years). 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 20 Jan 2025.
