Health Status of < 50 Year Old Patients After Surgically Implanted Biological and Mechanical Aortic Valves: a Population-based Retrospective Analysis (2010-2020)

Health Status of < 50 Year Old Patients After Surgically Implanted Biological and Mechanical Aortic Valves: a Population-based Retrospective Analysis (2010-2020)

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 2010-2020 in under 50 year old patients.

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, MACE (secondary outcomes) after aortic valve replacement in under 50 year olds. 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 2010-2020.

Inclusion Criteria:

• isolated surgical aortic valve replacement in Austria

Exclusion Criteria:

• below 18 years of age
• above 50 years of age
• concomitant heart surgery
