Evaluation of the Elastic Properties of the Thoracic Descending Aorta with Strain-Rate Measurement with Transesophageal Echocardiography: Its Correlation with the Left Ventricular Diastolic Function Assessed with Transthoracic Echocardiography

Aortic valve calcification and increased stiffness of the proximal thoracic ascending aorta: association with left ventricular diastolic dysfunction and early chronic kidney disease

“…The decreased vessel wall radial strain measured by Doppler imaging is an important supplement to assessment of the elastic properties of the thoracic aorta and is more accurate than wall velocities, presumably because the systolic deformation is more uniformly distributed in all aortic segments. In our experience, SR measurements obtained with transesophageal echocardiography could be used to detect disturbances of thoracic descending aorta distensibility and recoil at the early stage of arteriosclerosis, as well as the effects of these aortic changes on LV diastolic function [21].…”

Assessment of aortic elasticity and its relation with left ventricular filling and diastolic parameters by transthoracic and transesophageal echocardiography

“…To quantify the aortic elasticity, many techniques can be used such as transthoracic echocardiography (TTE) or transesophageal echocardiography (TEE), magnetic resonance imaging, and computed tomography (CT) (7)(8)(9). However, there are very limited studies related to assessment of aortic elasticity on TEE (10)(11)(12)(13)(14)(15)(16). Moreover, in majority of these studies, the elastic properties of aorta were measured on descending aorta in contrast to TTE studies and there were only a few data regarding to elasticity indices of ascending aortic by TEE.…”
