[Low-flow low-gradient aortic valve stenosis : Current evidence].

Many patients with severe aortic stenosis have a "low-flow, low-gradient" aortic stenosis. The management of these patients can be quite difficult, as these patients often show impairment of the left ventricle, which can lead to false measurements of the severity of stenosis and also leads to a higher risk during aortic valve replacement. More diagnostic tools than only standard echocardiography are needed to correctly differentiate true severe aortic stenosis from pseudo severe aortic stenosis.

Predicting long-term outcomes of acute aortic dissection: a focus on gender.

Acute aortic disease ranks as the 19th leading cause of death with steadily increasing incidence. The prevalence of aneurysms varies depending on the localization along the aorta with a mortality of aortic rupture of around 80%. Traditionally, aortic disease affects men more frequently than women, however, with a varying gender ratio.

[Risk evaluation of type B aortic dissection: importance for treatment of acute aortic syndrome].

Acute aortic syndrome (AAS) is a modern term used to describe interrelated emergency aortic conditions with similar clinical characteristics and challenges including aortic dissection, intramural hematoma (IMH) and penetrating aortic ulcer (PAU). Population-based studies suggest that the incidence of aortic dissection ranges from 2.6 to 3.
