SIZEADULTSQuantification of the age- and gender-specific in vivo mechanical characteristics of the ascending aorta (AA) will allow for identification of abnormalities aside from changes brought on by aging alone. Multiphase clinical CT scans of 45 male patients between the ages of 30 and 79 years...
Age, sex, and body size (both BSA and height) were all significantly associated with aortic size at both the sinuses of Valsalva and the ascending aorta. The presence of hypertension was also significantly associated with aortic size at both locations, while other clinical markers of ...
cross-classification, cross-division - classification according to more than one attribute at the same time; "the cross-classification of cases was done by age and sex" subsumption - incorporating something under a more general category 3. sorting - grouping by class or kind or size grouping -...
Is a 4 cm aorta normal? The normal diameter of the ascending aorta has been defined as<2.1 cm/m2and of the descending aorta as <1.6 cm/m2. The normal diameter of the abdominal aorta is regarded to be less than 3.0 cm. The normal range has to be corrected for age and sex, as wel...
BACKGROUND:Acute intramural hematoma (IMH) of the ascending thoracic aorta and aortic arch is a life-threatening condition, particularly in elderly patients with comorbidities, due to its risk of progression and rupture. Unlike aortic dissection, IMH lac
In contrast, at the DAo, the BAV patients had a more distensible aorta at all ages with a similar age related decline in distensibility, compared to CTD. Notably, although the BAV group had a higher prevalence of aortic valve stenosis and regurgitation, this did not significantly impact the...
The aorta contains numerous cell types that contribute to vascular inflammation and thus the progression of aortic diseases. However, the heterogeneity and cellular composition of the ascending aorta in the setting of a high-fat diet (HFD) have not been
An aneurysm of the ascending aorta encountered during an aortic valve operation may be of limited size. It is tempting under these conditions to use a less radical operation than graft replacement, such as reduction aortoplasty, especially in high-risk elderly patients in whom a decreased aortic ...
Full size table Overall, atherosclerotic plaques were detected in 336 segments; 164 segments in the proximal section of the ascending aorta and 172 segments in the distal section of the ascending aorta. Atherosclerotic disease affected only one segment of the ascending aorta in 50.3% (n = 80...
