The size of the ascending aorta may increase due to aging or pathologic conditions. The authors consider an aortic root or ascending aorta diameter above 4.0 cm as abnormal. From a diameter of >4.0 cm begins a monitor-zone for extended diagnostic evaluation, treatment advices and pre-pregnancy ...
even preserved thickness with dilation requires an increase in totalaortic tissuemass. As a result, the concentration of aortic elastin decreases by approximately one-third over 8 decades of life.43,44The total mass of elastin likely remains constant in theascending aortaand the decrease in concentr...
Aortic size at the sinuses of Valsalva was slightly larger among female rowers than runners (mean [SD], 33.7 [3.3] mm; 95% CI, 33.1-34.3; vs 32.3 [2.9] mm; 95% CI, 31.6-33.1; P = .008), but there was no difference across sports in the ascending aorta (mean [SD]...
An increase in orifice size of the stoma with time was documented in eight patients. Additional subsequent palliative surgery was required in 22 per cent (45/208). Mortality rate was directly related to age to operation and was highest in neonates less than one week of age. In infants with...
A relatively greater aortic expansion rate was identified as a risk factor for late mortality (p=0.015, HR 1.08 (CI: 1.02 to 1.15).ConclusionsConcomitant replacement of the dilated ascending aorta during AVR did not increase the immediate postoperative morbidity or mortality risks and tended to ...
Full size image Expression of cell junction and RHOA and NOTCH pathway-related proteins in internal thoracic artery To investigate whether the observed differences were specific for the ascending aorta, internal thoracic arteries of the same patients were stained with antibodies used for aortic intima-...
Download: Download full-size image Fig. 1. Comparison of the rate of change in aortic stiffness parameters in bicuspid aortic valve (BAV) and connective tissue disorder (CTD) patients at the ascending aorta (AAo) and descending aorta (DAo). Each trendline represents the average change in the ...
Cardiovascular disease: High-fat diets cause changes to aorta cells RNA sequencing of aorta cells reveals how key changes in cell populations and gene expression caused by a high-fat diet can increase risk of cardiovascular diseases. Xin Ma and co-workers at Jiangnan University in Wuxi, China, ...
Catastrophic ascending aorta aneurysm (AsAA) dissection and rupture can be prevented by elective surgical repair, but identifying individuals at risk remains a challenge. Typically the decision to operate is based primarily on the overall aneurysm size, which may not be a reliable indicator of risk....
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...
