Detection of atherosclerotic lesions in the aorta by transesophageal echocardiography

Association Between Large Aortic Arch Atheromas and High-Intensity Transient Signals in Elderly Stroke Patients

“…Previous studies have included a smaller number of patients with AAs, mainly referred for echocardiography to rule out a cardiac source of embolization, and most of them had atrial fibrillation, prosthetic cardiac valves, or cardiac thrombus. 1,3,[7][8][9][10][11][12]18,23,24 The clinical relevance of HITS in the cerebral circulation in patients with cardiac and carotid artery disease is still uncertain. However, several studies have found an association between HITS and increased risk of stroke.…”

Aortic Atheromatous Lesions Developed in APA Hamsters with Streptozotocin induced Diabetes: A New Animal Model for Diabetic Atherosclerosis. 1. Histopathological Studies.

“…Fatty masses sometimes found at 26 WAI are likely to separate from the aortic walls, resulting in embolisms in smaller arteries or arterioles [4,14,24,41,42]. Large plaques consisting of many FCs and SMCs in the aorta and carotid artery bifurcation walls or many small fatty plaques in the carotid arteries possibly decrease the blood flow in the carotid arteries and are suspected of causing brain ishchemia and stroke [9,20,21,44].…”

Aortic Sinotubular Atherosclerotic Debris Associated with Cerebral Embolic Events Can Be Identifiedby Transthoracic Echocardiography

“…Protruding and/or ulcerated atheromas in the ascending thoracic aorta or aortic arch are usually identified by transesophageal or epiaortic echocardiography as atherosclerotic debris and have been associated with cerebral and/or peripheral embolic events [1, 2, 3, 4, 5, 6, 7]. Recently, transcutaneous B-mode ultrasonography performed from a lateral supraclavicular approach has been proposed for identification of aortic root and arch pathology, but this technique failed to detect simple plaques in the proximal ascending aorta [8].…”
