Filter by:Left ventricular thrombus is a common complication subsequent to ST-segment elevation myocardial infarction (STEMI) that related to increased embolic events. This study aims to assess the efficacy and safety outcomes of Rivaroxaban on the prevention of post-STEMI left ventricular thrombus.
The incidence of rheumatic heart diseases have not declined in our population .Rheumatic heart diseases, often neglected by media and policy makers, is a major burden in developing countries where it causes most of the cardiovascular morbidity and mortality in young people, leading to about 250000 deaths per year worldwide. Mitralstenosis is one of the most common complications of rheumatic heart diseases in our community. A treatment of choice in suitable cases is percutaneous Mitral Commissurotomy .Preoperative evaluation for Percutaneous Mitral Commissurotomy typically requires trans-esophageal echocardiogram (TEE) for the presence of LA thrombus. TEE is currently considered the gold standard for LA thrombus detection given its favorable sensitivity and specificity . With recent advances,CMRis now becoming another reliable diagnostic method for evaluation of thrombus in the left atrium, particularly when delayed imaging is performed. Whereas TEE is a semi-invasive procedure, CMRis totally non-invasive . Effectiveness of left ventricular thrombus detection by CMR has been validated, and it is now becoming a preferred imaging modality for evaluation of left ventricular thrombus . Moreover, in patients undergoing pulmonary vein isolation,Cardiac Magnetic Resonance was validated against TEE for LA & left atrial appendage . To our knowledge, there are few data regarding the utility of Cardiac Magnetic Resonance for detection of LA thrombus in patients undergoing Percutaneous Mitral Commissurotomy.
The aim of this study is to evaluate the efficacy of rifaximin in the treatment of portal vein thrombosis in cirrhotic patients
Management of venous thromboembolism (VTE) in patients with cancer is complex and require the intervention of many specialized health professionals, in hospital but also at home and during follow-up. The AlloTC project aims to integrate the management of VTE within the multidisciplinary care pathway of the patient with cancer, in order to improve the management of VTE in patients with cancer: optimize treatments and follow-up with appropriate anticoagulants, monitor the implementation of good clinical practice, promote patient involvement and adherence. The objective of this monocentric study is to evaluate the efficiency of the integration of the therapeutic management of VTE into a specific management of patient with cancer and to set up a specialized "AlloTC" team that coordinates this course of care. For that purpose, the management of VTE and outcome of patients with cancer and VTE will be compared between two periods : traditional management and management with the "AlloTC" team.
Atrial fibrillation (AF) is the most frequently encountered cardiac arrhythmia. Emerging data suggests that common genetic variants are associated with the development of AF. The main feature of the structural remodelling in AF is atrial fibrosis and is considered the substrate for AF perpetuation. Genome-wide association studies suggest that AF-susceptibility variants may modulate atrial fibrosis. However, the association between atrial fibrosis and genetic polymorphisms in humans has not yet been specifically investigated. In this study, we plan to investigate the relationship between genetic polymorphisms, atrial fibrosis and other components of thrombogenic substrate in patients with non-valvular AF. Primary objectives of this study are to assess associations between (i) polymorphic genetic variants and atrial fibrosis (detected by magnetic resonance imaging), (ii) polymorphic genetic variants and components of thrombogenic substrate (inflammation, endothelial function, prothrombotic state, atrial functions).
The purpose of the study is to compare outcome of patients with effort thrombosis who were treated operatively to those treated nonoperatively
Initial treatment in the management of acute mesenteric vein thrombosis (MVT) is controversial. Some authors have proposed a surgical approach, whereas others have advocated medical therapy (anticoagulation). In this study, the investigators analyzed and compared the results obtained with surgical and medical treatment to determine the best initial management for this disease.
Hemodialysis catheter related bacterial infections represent a major cause of mortality and morbidity in the hemodialysis population. Several locking agents had been tried with variable degree of success but not without side effects. Neutrolin catheter locking agent comprises of heparin,citrate and trauolidine that had been studied in a prospective study in Germany, and it demonstrated a very good result in terms of reducing the catheter related infections and thrombosis. This study is a multi-center, double-blind RCT comparing the hemodialysis catheter locking solution Neutrolin with heparin in reducing the rate of catheter related bacterial infection and thrombosis.
A multi-center study will be done to explore the optimal regimen of antithrombotic therapy for acute myocardial infarction with left ventricular mural thrombus. The investigators will evaluate the different combinations of antiplatelet drugs and anticoagulants for at least one month, such as aspirin 100mg qd+clopidogrel 75mg qd+warfarin (INR1.8-2.2), aspirin 100mg qd+clopidogrel 75mg qd+dabigatran 110mg bid, aspirin 100mg qd+ticagrelor 60mg bid+warfarin (INR1.8-2.2), and aspirin 100mg qd+ticagrelor 60mg bid+dabigatran 110mg bid. Transthoracic two-dimensional echocardiography will be done at the 1-month, 3-month and 6-month follow-ups to evaluate the left ventricular mural thrombus and determinate whether the antithrombotic therapy regimen could be regulated to double antiplatelet or anticoagulant+clopidogrel 75mg qd/ticagrelor 60mg bid. Then the investigators will complete the 12-month follow-up to evaluate the efficacy and safety of the optimal antithrombotic therapy regimen for acute myocardial infarction with left ventricular mural thrombus.
Infusion therapy comprises the parenteral administration of solutions, through peripheral or central vascular access. Some solutions and drugs are highly irritating to the vascular endothelium and therefore cannot be administered in peripheral vessels, because increase the risk of phlebitis and/or tissue necrosis. Thus, the alternative is the central venous catheter (CVC) where the access can be by direct puncture of a central vessel or peripheral vessel puncture with progression of the catheter until central positioning, through a peripherally inserted central catheter (PICC). We must take into account that indication, insertion, handling and maintenance must be balanced with risks, benefits and costs. The insertion and maintenance of both catheters are not free of complications. Among the most frequent are: Infection, thrombosis, lumen occlusion and accidental early removal of the catheter. This often implies in the need for new vascular access, impacting on morbidity and increased treatment costs. The PICC has some advantages over CVC, for example: avoids repetitive punctures and consequently decreased handling/pain; a lower risk of infection; avoids the use of venous dissections; reduces the risks of pneumothorax/hemothorax; reduces the risk of infiltration, extravasation, necrosis tissue and chemical phlebitis. Further, the PICC can be used as a long-term catheter with easy handling in extra-hospital condition. All these advantages suggest that this technology offers lower cost to the health system and more benefits for patients. However, PICC is not available for use in infusion therapy in patients of the Brazilian public health system, except for neonates. The available literature does not address cost-effectiveness studies of this technology in the international scope comparing the PICC versus CVC. And, similarly, we do not have studies conducted in Brazil to incorporate this technology into our public health system, based on its benefits and potential cost reduction. In order to fill this gap, this study aims to test if the use of PICC in patients with infusional therapy equal or superior to 10 days (Intervention Group), will show a lower incidence in the outcomes (infection, thrombosis or mechanical complications), besides being more cost-effective when compared to the use of CVC of short stay (Control Group).
