Health Status of Patients After Surgically Implanted Biological and Mechanical Aortic Valves: a Population-based Retrospective Analysis (2010-2018)

The overall project aim is to study outcomes following aortic valve replacement with either mechanical valves or bioprostheses by retrieving data from the main social security carriers in Austria for the years 2010-2018.

About this study

The purpose of this research project is to evaluate mortality (primary outcome) and incidence of heart attack, stroke, reoperation and first diagnosis of heart insufficiency (secondary outcomes) after aortic valve replacement. We aim to compare those outcomes between mechanical valves and bioprostheses.

Data will be retrieved from the main social security carriers in Austria (covering 98% of its population) from 2010-2018.
