Filter by:EARTH-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.
The primary objective of this study is to investigate the impact of continuous renal replacement therapy and intermittent renal replacement therapy on microbubble / cerebral microemboli generation in a cohort of critically ill patients with dialysis-dependent acute kidney injury.
Because 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.
In this study, the investigators would like to compare a heparin-coated tubing system for minimized extracorporeal circulation (MECC) with the conventional tubing system for MECC, which does not contain heparin coating. The MECC system has been used since 14 years in the investigators' hospital as an extracorporeal system to support circulation and provide oxygen to the tissues during coronary artery bypass grafting. Until today, the investigators performed more than 5000 MECC procedures in their department.
The purpose of this study is get to know what and how Shuxuening injection in hospital results in adverse events or adverse drug reactions from a cohort event monitoring.
The purpose of this study is to determine the incidence of major vascular events (ischemic or haemorrhagics) at the third month after initiation of the antithrombotic treatment (oral anticoagulation or dual antiplatelet therapy) in both arms followed TAVI.
Radiofrequency catheter ablation of atrial fibrillation (AF) induces a procoagulant state, which leads to an acute risk for symptomatic cerebral embolism (CE) of approximately 1%. The induction of a procoagulant state has been studied in pulmonary vein isolation (PVI) with a non-cooled tip catheter. The induction of a procoagulant state using a cooled-tip catheter has not been studied yet. Due to the avoidance of high endocardial temperatures, it can be expected that these procedures induce a lower level of procoagulation. Recent studies showed an 11% incidence of CE on diffusion weighted (DW) MRI in patients undergoing cooled-tip catheter ablation of AF. In this study there will be used to different catheters, the cooled-tip catheter and the PVAC Gold catheter. Since the PVAC Gold catheter is equipped with non-cooled electrodes, the risk of endothelial scarring, local thrombosis and CE may be increased. The goal of this study is to determine the effect of two different ablation catheters on the induction of a procoagulant state and the incidence of CE on DW-MRI in patients with AF undergoing PVI. Our hypothesis is that patients with AF undergoing PVI using the PVAC gold catheter will show a higher rise in procoagulation and a higher incidence of CE on DW-MRI than patients with AF undergoing PVI with the cooled-tip catheter.
The purpose of this study is to determine whether autologous bone marrow mononuclear cells transplantation after stroke is safe and/or effective to improve neurological outcome.
The 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.
The purpose of this study is to determine, in patients undergoing carotid endarterectomy, the effect of ARC1779 Injection on the number of microembolic signals detected by transcranial Doppler immediately after surgery. This study will also evaluate the safety of ARC1779 Injection with respect to bleeding risk in patients in the peri-operative (during surgery) period.
