Filter by:Calcified cerebral embolism (CCE) is a relatively rare but underdiagnosed cause of infarction. CCE diagnosis is made by CT. Radiological characteristics of CCE have been reported in small case series. The aim of this study was to describe clinical and radiological characteristics of CCE in a large number of patients, and to compare patients with different radiological CCE characteristics.
The primary objective of this investigation is to compare the efficacy of two different antithrombotic strategies after percutaneous LAA occlusion with a Watchman device on the prevention of silent cerebral embolism.
The purpose of this clinical study is to assess the safety, performance, and treatment effect of the use of the AorticLab FLOWer System, in preventing cerebral thromboembolic complications in patients with indication for a TAVI (Transcatheter Aortic Valve Implant).
The purpose of this prospective randomized controlled study is to evaluate the risk of asymptomatic cerebral embolism during catheter ablation of atrial fibrillation (AF) with AI-HPSD strategy versus standard radiofrequency ablation settings, with the diagnosis of asymptomatic cerebral embolism is determined by brain high-resolution diffusion-weighted magnetic resonance imaging technique.
During different interventional cardiology procedures we aim to identify cerebral microemboli load. Further we aim to differentiate the quality and the quantity of cerebral microemboli.We will measure cerebral microemboli in different interventional phases, e.g. during valve deployment, rapid pacing, post-implantation.
Remote ischemic postconditioning (RIPC) is suggested to protect the cerebral cell against ischemia in various settings. However, the effect of RIPC in patients with acute ischemic stroke who undergo thrombolysis has yet to be examined. In this single-center, randomized controlled trial, we examined the effect of RIPC on the resolution of nerve function deficient in response to thrombolysis. Patients in the RIPC group had five cycles of 5-min cuff inflation followed by 3-min deflation to the bilateral upper arm after thrombolysis. The primary endpoint was the recovery of nerve function deficient assessed by National Institutes of Health Stroke Scale(NIHSS), Activities of Daily Living(ADL), Modified Rankin Scale(mRS), CT cerebral perfusion imaging (CTP) and CT angiography(CTA). Secondary endpoints included the following: angiogenesis assessed by the level of vascular endothelial growth factor (VEGF), basic fibroblast growth factor (bFGF).
The objective of the MEDIS study is to determine if subjects experiencing an Acute Ischaemic Stroke due to large vessel occlusion, treated with IV tPA combined with the MED procedure have a greater likelihood of recanalisation 30-90 minutes after the completion of tPA infusion than subjects treated with IV tPA (plus sham device). Safety of the MED System Procedure will be evaluated by the incidence of symptomatic PH-2 haemorrhagic transformation within 24 hours following the procedure. Lastly, a health economics study will be conducted to estimate health care costs for each treatment.
Prevention for the Restenosis of Intracranial artery Stent Implantation Treated with herbal medicine C117--PRISIT Trial
TAVI is increasingly adopted as standard treatment for many subgroups of patients with aortic stenosis. However, due to a lack of data there is yet no TAVI-specific guidance regarding the optimum periinterventional drug regimen. The study evaluates the effect of dual antiplatelet pretreatment on periinterventional embolic cerebral lesions and bleeding complications in patients undergoing transfemoral aortic valve implantation (TF-TAVI).
The purpose of this study is to study the effects of transthoracic electrical cardioversion for restoration of sinus rhythm in patients who present with recent onset atrial fibrillation, with regard to new silent cerebral thrombo-embolic lesions and cognitive function, as well as electrical and functional/structural reverse remodelling, and its effects on inflammatory changes / specific cardiac biomarkers, vasoactive peptides, coagulation activity, and active fibrinolysis.
