Active clinical trials for "Embolism"

A prospective, multicenter, randomized controlled trial of the FlowTriever System compared to Catheter-Directed Thrombolysis (CDT) for use in the treatment of acute pulmonary embolism. The trial includes a non-randomized cohort of subjects with an absolute contraindication to thrombolysis.

In this study, we will assess the efficacy and safety of a reduced dose of thrombolytic therapy given in addition to low-molecular-weight heparin in patients with intermediate-high-risk acute pulmonary embolism. Half of participants will receive thrombolytic treatment, while the other half will receive a placebo.

Researchers are looking for a better way to treat people with atrial fibrillation and prevent stroke or systemic embolism (blood clots travelling through the blood stream to plug another vessel). Atrial fibrillation is a condition of having irregular and often rapid heartbeat. It can lead to the formation of blood clots in the heart which can travel through the blood stream to plug another vessel, and like this lead to serious and life-threatening conditions, such as a stroke. A stroke occurs because the brain tissue beyond the blockage no longer receives nutrients and oxygen so that brain cells die. As strokes arising from atrial fibrillation can involve extensive areas of the brain, it is important to prevent them. Blood clots are formed in a process known as coagulation. Medications are already available to prevent the formation of blood clots. When taken by mouth (orally), they are known as oral anticoagulants (OACs) including apixaban. OACs decrease the risk of the above-mentioned serious and life-threatening conditions. The main side effect of OACs is an increase of the risk of bleeding. The study treatment asundexian is a new type of anticoagulant currently under development to provide further treatment options. Asundexian aims to further improve the standard of care with regard to the risk of bleeding. The main purpose of this study is to collect more data about how well asundexian works to prevent stroke and systemic embolism and how safe it is compared to apixaban in people with atrial fibrillation and at high risk for stroke. To see how well the study treatment asundexian works researchers compare: how long asundexian works well and how long apixaban works well after the start of the treatment. Working well means that the treatments can prevent the following from happening: stroke and/or systemic embolism. The study will keep collecting data until a certain number of strokes or embolisms happen in the study. To see how safe asundexian is, the researchers will compare how often major bleedings occur after taking the study treatments asundexian and apixaban, respectively. Major bleedings are bleedings that have a serious or even life-threatening impact on a person's health. The study participants will be randomly (by chance) assigned to 1 of 2 treatment groups, A and B. Dependent on the treatment group, the participants will either take the study treatment asundexian by mouth once a day or apixaban by mouth twice a day for approximately 9 - 33 months. Each participant will be in the study for approximately 9 - 34 months. There will be visits to the study site every 3 to 6 months and up to 7 phone calls. Those participants who do not want or are unable to have visits to the study site may join the study remotely in selected countries. During the study, the study team will: take blood samples do physical examinations examine heart health using an electrocardiogram (ECG) check vital signs such as blood pressure and heart rate do pregnancy tests ask the participants questions about their quality of life ask the participants questions about how they are feeling and what adverse events they are having. An adverse event is any medical problem that a participant has during a study. Doctors keep track of all adverse events that happen in studies, even if they do not think the adverse events might be related to the study treatments.

This study aims to compare the efficacy and safety of the edoxaban and the warfarin in atrial fibrillation patients with mitral stenosis. The study design is a multicenter, randomized, open-label, investigator initiated phase 2 trial. The patients were randomly assigned to Edoxaban or Warfarin groups. Primary outcome was a composite of stroke and systemic arterial thromboembolism. The safety outcome was major bleeding.

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.

This trial is a prospective, randomized, multicenter, multinational, blinded, superiority trial. The objective of this trial is to evaluate the effectiveness of left atrial appendage exclusion (LAAE) for the prevention of ischemic stroke or systemic arterial embolism in subjects undergoing cardiac surgery who have risk factors for atrial fibrillation and ischemic stroke.

A PMCF study to confirm the performance and safety of the LeMaitre® TufTex Over-the-Wire Embolectomy Catheter

No randomized head-to-head comparison between the individual Non-vitamin K Antagonist Oral Anticoagulants (NOAC) exists. The DANNOAC-VTE study is a nationwide cluster randomized cross-over study comparing efficacy and safety of the four NOACs, edoxaban, apixaban, rivaroxaban and dabigatran for oral anticoagulation in venous thromboembolism across Danish hospitals.

The goal of this multicentric clinical trial is to compare the incidence of pulmonary thromboembolism (PTE), assessed through AngioCT, in the endovascular treatment of acute thrombosis in native and prosthetic arteriovenous fistulas (AVF). The main questions it aims to answer are: What is the difference in the incidence of pulmonary thromboembolism (PTE) assessed by AngioCT in endovascular treatment of acute thrombosis of native and prosthetic arteriovenous fistulas using balloon thrombectomy versus thromboaspiration systems? What is the primary patency rate of arteriovenous fistulas treated with balloon thrombectomy versus thromboaspiration systems? What is the clinical success rate in the treatment of arteriovenous fistulas using balloon thrombectomy compared to thromboaspiration systems? What are the costs associated with the different thrombectomy techniques in the treatment of arteriovenous fistulas? Participants will be underwent to balloon thrombectomy versus thromboaspiration systems. Researchers will compare the patients treated with balloon thrombectomy and thromboaspiration systems to see if the incidence of PE is comparable and to evaluate the primary and secondary patency rates of both thrombectomy techniques, the clinical technical success rate, and the costs associated with each technique.

PE-TRACT is an open-label, assessor-blinded, randomized trial, aiming to compare catheter-directed therapy (CDT) and anticoagulation (CDT group) with anticoagulation alone (No-CDT) in 500 patients with submassive PE, proximal pulmonary artery thrombus and right ventricular dilation.
