Brief summary
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.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Occurrence within 5 years of inclusion of a major aortic even | during the 5 years after inclusion | This composite end point is defined as the occurrence of: * Aneurysm-related death * Emergency surgery for threatened aortic rupture or aortic dissection * Scheduled surgery for aneurysmal dilatation of more than 5 mm over 1 year * Aneurysm progression exceeding 55 mm in diameter * Root surgery for management of symptomatic aortic valve disease (insufficiency or narrowing) of high grade defined by tight aortic narrowing (V Max≥4 m/s, mean gradient ≥40mmHg, and area ≤1cm² or severe aortic insufficiency (regurgitated volume≥60 ml, shortening fraction≥ 50%. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Number of Participants with controlled blood pressure defined by ambulatory blood pressure measurement | during the 2 years after inclusion | The blood pressure measurement (averaged over 24 h)\<130/80 mmHg and nocturnal blood pressure ≤120/70 mmHg |
| Presence of sleep disorders defined by an 'Apnea Hypopnea Index and/or an Oxygen Desaturation Index | during the 2 years after inclusion | for Apnea Hypopnea Index = ≥5 events per hour for Oxygen Desaturation Index = ≥5 events per hour |
| Occurrence during the 5 years after inclusion of a major cardiovascular event | during the 5 years after inclusion | This composite criterion is defined by the occurrence of death from cardiovascular causes, myocardial infarction, stroke (ischemic or hemorrhagic), or hospitalization for heart failure |
