Active clinical trials for "Aortic Valve Stenosis"

Transcatheter aortic valve replacement (TAVR) is a well-established alternative to surgical aortic valve replacement (SAVR) for the treatment of patients with severe aortic stenosis regardless of surgical risk. While TAVR and SAVR share some of the benefits and risks, they importantly differ with regards to invasiveness, time to recovery, hemodynamics, as well as options for re-intervention and possibly valve durability. An early benefit of TAVR may be offset by late risks. Therefore, current guidelines of the European Society of Cardiology recommend an integration of patient values and preferences for the selection of the treatment modality. The objective of the TOGETHER trial is to investigate the efficacy of a structured shared decision making approach (SDM) to improve patient-centered outcomes for the choice between SAVR and TAVR. TOGETHER is an investigator-initiated, randomized, open-label, single-center clinical trial. A total of 140 patients referred for treatment of symptomatic severe aortic stenosis and deemed to undergo TAVR or SAVR according to heart team decision will be randomized in a 1:1 ratio to structured SDM or usual care.

This prospective, randomized-controlled multicenter study investigates whether virtual reality-assisted patient education in patients undergoing transfemoral transcatheter aortic valve implantation (TAVI) can improve patient understanding and simulative orientation, thereby reducing postinterventional complications, resulting in significantly shorter length of stay.

Anesthetic agents can cause hypotension, and be especially dangerous in patients with severe aortic stenosis, which can lead to even circulatory collapse. Remimazolam is known for its hemodynamic stability compared to propofol. This study is designed to compare effects of remimazolam vs. sevoflurane anesthesia on intraoperative hemodynamics in patients with severe aortic valve stenosis.

This is a prospective, non-randomized, single arm, multicenter, multinational two-stage FIH feasibility followed by pivotal study in symptomatic patients with severe aortic stenosis.

The goal of this clinical trial is to learn about the safety and performance of the F2 device for cerebral embolic protection in participants with symptomatic aortic stenosis underdoing a Transcatheter Aortic Valve replacement procedure. Participants will complete several neurocognitive assessments and an MRI procedure.

The purpose of this clinical study is to assess the safety, performance, and treatment effect of the use of the AorticLab FLOWer System, in preventing cerebral thromboembolic complications in patients with indication for a TAVI (Transcatheter Aortic Valve Implant).

Aortic stenosis is a progressive disease that affects approximately 3% of adults aged 75 and over. If left untreated, the mortality rate of aortic stenosis, which becomes symptomatic in a short time, is 50% in the first year, while this rate rises to 90% within 5 years. Surgical treatment of aortic stenosis has been proven to reduce symptoms and increase survival. Although surgical treatment is considered the gold standard, 30% of elderly patients cannot undergo surgery due to left ventricular dysfunction and comorbidities. The search for new methods with a low-risk rate and a more comfortable post-procedure process has begun. For this purpose, Cribier et al. Transcatheter aortic valve implantation (TAVI) was developed in 2002 as an important alternative to surgical aortic valve placement. The TAVI method; is the procedure of inserting a bioprosthetic aortic valve into the heart using the catheter method without open heart surgery. Although transcatheter aortic valve implantation is more tolerable than surgery, it has certain complications. According to the Valve Academic Research Consortium (VARC-3), common post-procedural complications are; stroke, myocardial infarction, bleeding, major vascular complications, and acute kidney injury. Nursing-specific care problems are stated as bleeding, infection, pain, decrease in cardiac output, and sleep problems. Many factors, such as the high risk of patients undergoing TAVI, the complexity of the procedure, and the complications that may develop after the procedure, require that the nursing care to be applied be specific and individualized to the TAVI procedure. It is very important to understand the experiences of the patients to effectively carry out this special care to be applied before and after TAVI. It is known that being aware of the experiences and needs will contribute positively to the care and treatment of future patients. Instens et al. stated that experiences can be reached by examining perspectives in depth rather than clinical studies or records. In this regard, Baumbusch et al. in their qualitative design study; It has been revealed that TAVI patients cannot manage their care after the procedure because of their age and comorbidities, there is a difference between their expectations and reality, and they need support in terms of information. In another study, the post-TAVI process was defined as a balance between the struggle for life and hope, and the importance of the support of health professionals during the process was emphasized. For these reasons, TAVI patients need nursing care support and information in terms of post-procedure disease management. The most important component of successful disease management is to increase the participation of the individual in his health. In this direction, nurse-led training and counseling programs are the leading methods that will increase the participation of patients in their health management, and research on this subject has been increasing in recent years. Jiang et al. In their study on patients with myocardial infarction, it was found that a nurse-led training and counseling program increased the quality of life and risk factor control. Boyne et al. In their study of heart failure patients, it was revealed that the knowledge, self-care, and self-efficacy of the patients increased after the intervention. Despite growing evidence for the benefits of nurse-led education and counseling programs, no studies have been found with TAVI patients who might need this intervention the most. The aim of this study; is to examine the effect of education and follow-up program on quality of life, self-care, treatment compliance and hospital readmission in patients who underwent TAVI.

Aortic stenosis (AS) is the most frequent valvulopathy in Western countries. The prevalence of AS is constantly increasing due to the aging of the population. Although significant progress has been made in understanding the pathophysiological mechanisms underlying the onset and progression of AS, there is no medical treatment to slow or prevent its progression. The only treatment available is Aortic Valve Replacement (AVR) performed by surgery or by catheterization (TAVI). Once a diagnosis has been made and the decision to treat these patients has been taken, the procedure (AVR or TAVI) must be performed rapidly given the poor prognosis of the disease without treatment. Studies have shown that on the waiting list, the probability of death and hospitalisation for heart failure increases with time. This delay could also reduce the effectiveness of TAVI, thus affecting the performance of the healthcare system. In this study, an intervention combining an e-health component (tool intended for patients, families and health professionals in contact with patients), and an organisational component (for TAVI implanting centres) has been designed. The aim of this study is to evaluate the effectiveness of this intervention.

The TAVI (Thubrikar Aortic Valve, Inc.) -1 Study: Safety and Performance Study of the Optimum Transcatheter Aortic Valve- First-in-human study to assess feasibility and safety of the Optimum Aortic Valve Implant

Study category and Rationale Clinical study, Category A. Clinical Phase: Post market study Background and Rationale: Left atrial appendage occlusion (LAAO) allows avoiding oral anticoagulation and provides at the same time an at least equally good protection from strokes and peripheral embolism. It may therefore be an attractive alternative to oral anticoagulation in the patient population undergoing transcatheter aortic valve implantation (TAVI): the concept of LAAO is based on the fact that thrombus formation in atrial fibrillation occurs in >90% in the left atrial appendage (LAA). Mechanical occlusion of the LAA reduces the stroke risk by eliminating the source of thrombus formation. In the here proposed "Randomized Comparison of Left Atrial Appendage Occlusion versus Standard Medical Therapy in Patients in Atrial Fibrillation Undergoing Transfemoral Transcatheter Aortic Valve Implantation", study we test the hypothesis, that LAAO is superior to standard medical therapy in the high-risk TAVI population. This hypothesis has not been investigated by previous studies so far. Overall Objective(s): Overall objective: to compare the safety (and efficacy) of LAAO using the St. Jude left atrial appendage closure device with standard medical therapy in a prospective, multi-center, randomized trial in patients undergoing TAVI in routine clinical practice. Primary Objective: To assess the safety of the device intervention with regard to stroke prevention and prevention of bleeding complications in a patients population at high risk of stroke and bleeding. Secondary Objectives: Short-term (procedural) safety of device intervention is assessed (rate of successful deployment of a left atrial appendage occluder; rate of kidney failure). As a further secondary objective, long-term effects of device intervention on stroke and bleeding prevention as well as mortality are assessed and compared to medical therapy. Outcome(s): Primary: Composite endpoint of ischemic and hemorrhagic neurologic events, peripheral embolism, life-threatening/disabling and major bleeding complications and cardiovascular mortality at 1 year Secondary: All deaths (cardiac and non-cardiac) at 30 days, 1, 3, and 5 years Device success at 30 days In-hospital acute kidney injury (AKI) Study design: An investigator-initiated, randomized, multicenter, non-blinded, all-comers study Measurements and Procedures: 80 patients in atrial fibrillation undergoing TAVI will be randomized in a non-blinded fashion (1:1 randomization) to LAAO (device group) or SMT at the operators' discretion (medical group; antiplatelet therapy and oral anticoagulation or oral anticoagulation alone). All patients will be followed for up to 5 years. The primary analysis will be performed at 30 days and after completion of a 1-year follow-up. 80 patients in atrial fibrillation undergoing TAVI will be randomized in a non-blinded fashion (1:1 randomization) to LAAO (device group) or standard medical therapy (SMT) at the operators' discretion (medical group; antiplatelet therapy, oral anticoagulation or oral anticoagulation alone). Estimated duration for the main investigational plan from start of screening of first participant to last participant processed and finishing the study: 6 years
