Left Atrial Appendage Closure During Open Heart Surgery
Atrial FibrillationCerebral Embolism1 moreBecause atrial fibrillation occurs frequently in heart surgery patients, our overall hypothesis is that systematic closing the left atrial appendage during surgery will reduce cerebral embolism coming from the thrombus formation in the left atrium. The specific hypothesis which sought tested is that closure of the left atrial appendage in connection with elective CABG and / or valve surgery will lead to fewer strokes and micro cerebral infarcts measured by MRI.
Boston Area Anticoagulation Trial for Atrial Fibrillation (BAATAF)
ArrhythmiaAtrial Fibrillation6 moreTo determine the benefits and risks of oral anticoagulant therapy in reducing embolic stroke and systemic emboli in patients with atrial fibrillation without rheumatic heart disease.
Dual AntiPlatelet Therapies for Prevention of Periinterventional Embolic Events in TAVI
Aortic Valve StenosisTranscatheter Aortic Valve Replacement1 moreTAVI 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).
Incidence of Acute Cerebrovascular Events Using Either Minimized or Standard Cardiopulmonary Bypass...
Coronary Artery DiseaseAcute Cerebrovascular Accident3 moreThe prospective, randomized, two centre study investigates acute cerebrovascular events during extracorporal circulation and the early post operative outcome when using either the minimized cardiopulmonary bypass circuit (ROCsafeTM) or a standard cardiopulmonary bypass circuit in patients undergoing coronary artery bypass grafting.
Ultrasound Enhanced Thrombolytic Therapy of Middle Cerebral Artery Occlusion
Intracranial EmbolismThrombosisThe purpose of the present, randomized, controlled multicenter phase III trial is to investigate the safety and efficacy of continuous 1-hour insonation of occluded middle cerebral artery with 2 MHz TCCS in stroke patients treated with intravenous tissue plasminogen activator (t-PA) within 3 hours after symptom onset.
Risk of Asymptomatic Cerebral Embolism During AF Ablation With AI-HPSD Strategy Versus Standard...
Atrial FibrillationThe 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.
Stroke Prevention in Sickle Cell Anemia (STOP 1)
AnemiaSickle Cell4 moreTo reduce episodes of first time stroke by 75 percent in children with sickle cell anemia by the administration of prophylactic transfusion therapy.
Evaluation of Cerebral Thrombembolism After TAVR
Aortic Valve StenosisTranscatheter Aortic Valve Replacement1 moreEARTH-TAVR is a diagnostic multicenter study to evaluate the occurrence and extent of cerebral embolization (total new lesion volume) in patients before TAVR versus 3 months after TAVR.

Electrical Cardioversion of Recent Onset Atrial Fibrillation - Silent Thromboembolic Events, Reverse...
Intracranial EmbolismThe 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.
