Background: Aortic diseases are prevalent and are a major health burden worldwide. Globally, it is estimated that more than 170,000 die every year due to aortic aneurysms alone. Aims: We seek to investigate characteristics, patterns, trends and outcomes of aortic diseases in the West of Ireland in the last two decades. In addition we will compare and contrast our findings in relation to international metrics. Hypotheses: Characteristics, patterns, trends and outcomes of aortic diseases in the West of Ireland could be different than the rest of the world. Methodology: We will collect clinical data, demographics, vital signs, imaging data, interventional data and outcomes of patients treated at the Galway University Hospital during the period between 2003 to 2023. We will run statistical analysis using conventional methods as well as advanced as advanced machine learning algorithms in order to describe patient characteristics, trends in patient phenotypes, management strategies, outcomes and predictors of outcomes. In addition, we will use statistical modelling to compare and contrast our findings to the rest of the world using available data from main regestries and clinical trials. Data will be presented as descriptive statistics and Kaplan-Meir survival curves.
