Who can take part

AI summary

From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.

The trial is looking for adults with a small or moderate aneurysm (a bulge) of the aortic root, who can be followed for 5 years.

Age
45 to 80 years
Sex
Men and women can join.
Disease stage
An aortic root aneurysm larger than 40 mm. Aneurysms of 50 mm or more cannot join.
Earlier treatment
Anyone with earlier aortic surgery or an endovascular (inside the vessel) procedure cannot join.

Main reasons for not taking part

  • Illness with an expected survival of less than 1 year
  • Genetic connective tissue disease, or signs suggesting Marfan disease
  • Severe heart valve disease, even without symptoms
  • Uncontrolled high blood pressure of 180/110 mmHg or more
  • Kidney failure on dialysis, or GFR below 30 ml/mn

Who can take part

  • Documentation of an aortic root aneurysm > 40 mm

  • Aneurysm (regardless of thoracic or abdominal location) ≥ 50 mm
  • Aneurysm (regardless of thoracic or abdominal location) with documented progression of more than 5 mm over one year

About the trial

What the trial wants to find out

Thoracic aneurysm is a silent disease with a potential mid-term high risk of death or major complications. Few data are available on the real incidence of major complications in case of small and moderate thoracic aneurysm. Different factors are supposed to increase the risk of aortic enlargement as high blood pressure and sleep disorder breathing. The modality of imaging and clinical follow-up are well defined. In this prospective observational study, the aim to assess the incidence of of major complications during follow-up in a population of patients with a small or moderate thoracic aneurysm. The study will also try to identify systemic factors influencing aneurysm evolution.

Questions to ask the study team

  1. How often do I need to come in, and for how long each time?
  2. Are travel costs paid?
  3. Can I keep my own doctor?
  4. What happens if I want to stop?
