Especially cardiovascular echo plays an important role in the primary evaluation of patients with suspicious aortic dissections, and the detection of a flap in the aorta can be a key to its diagnosis. Blaivas et al. reported on an ultrasonographic sign of dissection of the ascending aorta in ...
(IMH) is a variant of aortic dissection characterized by separation of the intima from the adventitia, with a hematoma within the medial layer (Fig. 19-13).30A typical feature of IMH is thatechocardiographycannot identify an intimal tear, although at times the hematoma will contain echolucent ...
A diagnosis of type I aortic dissection was ultimately made by echocardiography. At surgery there was a circumferential intimal tear in the aortic root, ... SP Goldberg,C Sanders,NC Nanda,... - 《Journal of Cardiovascular Surgery》 被引量: 23发表: 2000年 A Two-Dimensional Echoaortocardiograp...

The term acute aortic syndrome (AAS) refers to a range of different entities, including dissection, intramural haematoma and penetrating atherosclerotic ul
(eg, Marfan syndrome or aortic dissection) may cause enlargement of the aortic valve annulus; this results in failure of the leaflets to coapt (close) properly in diastole (loss of coaptation) and aortic regurgitation. Frequently, repairs to the aortic root and valve are required in these ...
These linear echo densities have characteristic features which distinguish them from a true intimal flap (septum). Their recognition is critical in avoiding false positive transesophageal echocardiography findings. The general consensus on operations for ascending aorta and aortic arch dissection is that ...

Unusual Echocardiographie and Doppler Findings in a Patient with Unsuspected Aortic Dissection A patient with aortic dissection, in whom the diagnosis was clinically not obvious is reported. In thiscase echocardiography proved useful in suggesting the correct diagnosis, demonstrating a serpen L Mancuso...
(see Fig.5), additional imaging is recommended. TOE is a useful adjunct to help clarify valve morphology, regurgitation mechanism and severity, and provides assessment for possible infection or dissection. TOE should also be considered pre-surgery where patients are undergoing aortic valve sparing or...
