Introduction: Care of aortic aneurysms (AA) consists of regular imaging follow-up and managing cardiovascular risk factors. OSA has been proposed to be associated with accelerated expansion of abdominal AA in observational studies. The purpose of this ongoing study is to evaluate whether OSA has an influence on the progression of thoracic aortic aneurysm (TAA).

Methods: In total, 340 people with known TAA are to be included in this prospective, observational study. In women the TAA is defined as aortic diameter > 39mm at the level of Sinus valsalvae and >42mm at the level of the ascending aorta. The values for men are >44mm and >46 mm, respectively. Each participant undergoes a home sleep study at baseline and at the 3-year follow-up. OSA is defined as Apnea-Hypopnea-Index (AHI) ≥ 5/h, and its severity classified into mild, moderate or severe according to the guidelines by the American Academy of Sleep Medicine (AASM). Each participant receives an annual TAA assessment by transthoracic echocardiography. The primary outcome is the yearly expansion rate of TAA in relation to OSA severity. The secondary outcomes encompass aortic events (ruptures, dissections), endovascular repairs and rapid progressions of TAA.
