Filter by:Atrial Fibrillation represents an important risk of cardioembolic stroke. In more than 90% of cases, thrombus originate in the left atrial appendage. Therefore guidelines recommend the anticoagulation of patients with atrial fibrillation and a significant cardioembolic risk, predicted by the CHA2DS2VASc score. However, serious bleeding complications may definitively contraindicate the use of anticoagulants. For those patients, percutaneous Left Atrial Appendage Occlusion (LAAO) has became a recommended alternative to prevent the thrombus formation and reduce the risk of cardioembolic events. In the CHU of Brest, more than 120 patients have been treated with LAAO for the last 8 years with two different occluder devices : WATCHMAN®, Boston Scientifc and AMPLATZER Amulet®, Abbott Laboratories. This retrospective longitudinal observational study named CLAPOT (CHU of Brest' Left Atrial Appendage Percutaneous Occlusion Treatment) aims to evaluate the long term results of this procedure for effectiveness and safety and to compare the results between the two devices (Watchman and Amplatzer).
INVISIBLE-1 aims to prospectively follow patients up to one year after ischemic stroke to: 1. Determine the cumulative incidence of occult cancer in patients with embolic stroke of undetermined source (ESUS) and elevated D-dimer 2. Describe occult cancer characteristics and spontaneous course of occult cancer Methodology The investigators will include 370 stroke patients with elevated D-dimer (≥ 820 μg/L) at the time of stroke, suspicion of ESUS after initial workup and without known cancer. The investigators will perform a follow-up telephone interview at one year to assess the occurrence of a new cancer and characterize the course of the disease. Significance Determining the real incidence of occult cancer in high-risk patients will help support the implementation of screening trials in the future. Faster detection and treatment of occult cancers would significantly impact patient' outcomes by offering faster cancer treatment and optimal secondary stroke prevention.
International medical centre Medicor from Slovenia has reported 306 successful percutaneous closures of patent foramen ovale (PFO) from October 2006 till June 2022. The investigators are going to follow-up the participants clinically and with contrast transthoracic echocardiography (TTE) to define the percentage of functional percutaneous closure. The latter is defined with the number (ten or less) of contrast-bubbles in the left atrium during Valsalva maneuver and contrast (agitated saline) application. The clinical follow-up will show the recurrence of embolic events (cerebrovascular insults, transient ischemic attacks) after percutaneous closure. In addition all of the participants are going to be screened for atrial fibrillation. The patients with moderate residual shunts (more than ten bubbles in the left atrium) will then according to the protocol have a transesophageal echocardiogram (TEE) to show the eventual mechanism of the shunt. If the TEE will not show any signs of a residual shunt, the patients will undergo a computed tomography angiogram (CTA) of the pulmonary circulation to exclude arterio-venous fistulas as a cause of the shunt seen on TTE. The investigators will also show the comparison in functional closure between classic and alternative device occluders.
Study Title: A real-world registry of multidisciplinary collaborative diagnosis and treatment models for cardioembolic stroke Research Objectives: ① Main objective: To establish a multidisciplinary assisted diagnosis and treatment model for patients at high risk of cardioembolic stroke, manage and collect the diagnosis, treatment and prognosis data of patients. ② Secondary objective: To investigate the improvement of cardioembolic stroke, cardiovascular complex events, recurrent stroke and all-cause mortality risk, quality of life, and cardiac function between the "multidisciplinary assisted treatment model" group and the "conventional treatment model group". The routine diagnosis and treatment mode can match the patients who did not adopt the "multidisciplinary assisted diagnosis and treatment mode" in the same period. Type of design: A prospective, observational, real-world study. No fixed diagnosis and treatment plan was established in advance, and only a multidisciplinary assisted diagnosis and treatment model was established. All treatment choices were made by clinicians according to the expert consensus of relevant textbooks and clinical guidelines, and according to the patient's condition. Subjects: From September 2022 to September 2023, high-risk patients with cardioembolic stroke were collected from the Second Affiliated Hospital of Nanchang University and sub-centers of hospitals at all levels in Jiangxi Province.
This is an observational, prospective, multicenter, cohort study in patients with cardioembolic stroke and previous oral or parenteral anticoagulant therapy. Patients in which anticoagulante therapy is mantained will be compared to those in which it is interrupted, in terms of stroke or systemic embolism and haemorrhagic transformation.
The ARIES study is an observational study in which patients with a recent acute ischemic stroke of cryptogenic aetiology are consecutively enrolled in order to perform a extensive cardiologic work-up. The main objective is to study parameters that could predict arrythmias on prolonged monitoring and also echocardiographic parameters of left atrial disfunction that could predict the presence of a hidden atrial fibrilation and recurrent ischemic events in patients with cryptogenic stroke.
The aim of the study is to evaluate the efficacy and safety of the Cardea SOLO Compared to 12 lead EKG for Paroxysmal Atrial Fibrillation Diagnosis in ESUS patients with Left Atrial Enlargement.
In adult patients presenting to emergency departments within 24 hours of symptom onset with suspected acute stroke, we aim: 1. to identify early brain- and pathology-specific circulating, whole blood, plasma and serum panorOmic biomarkers that enable early acute stroke detection, diagnosis, dynamics, differentiation, monitoring, prediction and prognosis. 2. to identify early brain- and pathology-specific, panorOmic biomarkers in saliva that enable early acute stroke detection, diagnosis, dynamics, differentiation, monitoring, prediction and prognosis. 3. to derive biomarker platforms of models for early acute stroke detection, diagnosis, dynamics, differentiation, monitoring, prediction and prognosis 4. to validate these models in independent and external datasets
This is a multi-center, randomized, double-blind, placebo-controlled trial of MLC1501 in patients with stroke. Eligible participants will be randomized in a 1:1:1 ratio to orally receive MLC1501 high-dose twice a day, MLC1501 low-dose twice a day, or matching placebo for 24 weeks.
Patent foramen ovale (PFO) is associated with an increased risk of stroke. PFO-closure was effective in preventing stroke in young stroke patients less than age 60 presented as an embolic stroke of undetermined source (ESUS). However, the benefit of PFO-closure in elderly ESUS patients is not clear. The investigators designed this prospective register-based observational study to verify the efficacy of PFO-closure in elderly ESUS patients with high-risk PFO, older than 60 years
