Objectives: Cardioembolism accounts for 15-30% of ischemic strokes. Transesophageal echocardiography (TEE) is useful in detecting potential sources of cardiac embolism. Aortic atheromas have recently been recognized as important causes of stroke. The aim of this study was to evaluate TEE findings in elderly patients with ischemic stroke. A review of literature was done to highlight the significance of aortic atherosclerotic disease in patients with ischemic stroke.
Methods: One hundred consecutive patients with ischemic stroke aged > or =55 years underwent TEE for evaluation of cardiac sources of embolism. Patients with significant carotid artery stenosis (stenosis of >50% in common or internal carotid arteries) were excluded.
Results: The most noteworthy finding was the high prevalence of complex atheromatous plaques in the ascending aorta and/or aortic arch (25%).
Conclusion: The present study demonstrates that TEE is helpful to detect cardiovascular sources of embolism in elderly patients with ischemic stroke. Aortic atheroma is present in 25% of elderly patients with ischemic stroke and without significant carotid artery stenosis. Aortic atherosclerosis may be an important cause of ischemic stroke in this population.

Introduction: Sarcopenia, characterized by reduced skeletal muscle mass (RMM), is increasingly recognized as a significant factor influencing outcomes in various health conditions, including stroke. Although most studies focus on sarcopenia developing during stroke rehabilitation, the impact of sarcopenia present at the onset of acute ischemic stroke remains underexplored. This study aims to evaluate the effect of RMM at stroke onset on 3-month functional outcomes in acute ischemic stroke patients.

Introduction: Radiological calcified cerebral embolism (CCE) characteristics have been reported in small case series. Our aim was to describe clinical and radiological CCE characteristics in a large number of CCE and to compare characteristics between different patient groups.
Methods: Characteristics of 79 stroke patients with CCE were analyzed retrospectively.

Introduction: Mechanical thrombectomy (MT) efficacy in medium vessel occlusion (MeVO) stroke, particularly in patients with low Alberta Stroke Program Early Computed Tomography Score (ASPECTS), remains less explored.
Methods: This retrospective study analyzed data from 443 AIS patients treated with MT for MeVO and low ASPECTS (4-7) at 37 centers across North America, Asia, and Europe, from September 2017 to July 2021. Patients were categorized into ASPECTS of 4-5 and 6-7.
