What this Trial Is About

Surgical indication in patients suffering from Ascending aorta aneurysm is currently based mainly on the maximum diameter of the aortic dilatation and on the yearly growth rate. Several clinical preoperative patients characteristics have been, potentially, correlated to impaired mechanical characteristics of aortic wall, and therefore to an increased risk of rupture and or dissection. On other hands, such suppositions have been never confirmed, as a full characterization of the mechanical behaviour of the ascending aortic tissue, especially in case of aneurysm, has not been fully clarified yet. Objective of this observational study is to better elucidate, using direct in vivo evaluation, the mechanical characteristics of the aortic wall in patients with ascending aorta diseases. Our study will have a further peculiar characteristic as we have the intention of compare such mechanical characteristics to those of patients, without known aortic diseases, undergoing heart transplantation. Potential correlation between, directly measured mechanical characteristics of the aortic wall, and preoperative parameters (anagraphic patients characteristics, clinical data and diagnostic tests) will be also investigated.
