Effective Treatments for Thoracic Aortic Aneurysms (ETTAA) Study is an observational clinical trial set up to try to find the most effective treatment for a potentially fatal chronic chest condition.

The five-year study, funded by the Health Technology Assessment (HTA) Programme, has been designed to collect information on patients who have been diagnosed with a chronic thoracic aortic aneurysm (CTAA) to determine the best management strategy, timing and cost effectiveness of different interventions for the treatment of CTAA.

The study will follow patients from a number of centres across the UK over a period of time to see how well they do. The type of treatment patients receive will not be altered by taking part in this study.

The results from this study will enable clinicians to make a more informed decision about which treatment option will be best for individual patients.

We aim to analyse all the information collected in order to:

  1. Understand the growth rate of chronic thoracic aortic aneurysms and identify which factors influence the growth rate
  2. Understand how quality of life changes whilst you are monitored prior to surgery, following any surgical procedures or over time if you have decided against having any treatment.
  3. Estimate the cost-effectiveness of the different treatment options by measuring changes in survival and quality of life of patients compared to the cost of treatment and post-operative patient care
  4. Create a risk score that will help specialists determine which treatment pathway is best suited to a given patient and when this treatment should be offered.
