Filter by:The study aims to evaluate composition differences of aortic valves in different stages and phenotypes of aortic stenosis using non-invasive imaging and histology.
Prior studies have shown that impaired endogenous fibrinolysis is a novel, independent cardiovascular risk factor in patients with myocardial infarction and there is currently no known chronic treatment to enhance endogenous fibrinolysis. To date, no therapies have been able to sufficiently reduce Lp(a) and therefore it was considered to be a non-modifiable cardiovascular risk factor. New data, however, has shown that PCSK9 inhibitors and inclisiran (medication that you have been deemed eligible for in order to help further reduce your cholesterol levels) to reduce Lp(a) levels by approximately 20-25%. The aim of this study to is to assess: 1. if there is an association between raised Lp(a) level in blood and the effectiveness of endogenous fibrinolysis (lysis time). 2. whether lowering Lp(a) with PCSK9i or inclisiran can enhance endogenous fibrinolysis
A prospective, single arm, exploratory clinical investigation to assess preliminary safety and collect performance and effectiveness data of the TRIFLO Heart Valve.
In this study, the investigators will evaluate the feasibility and potential efficacy of programs to improve functional outcomes after minimally-invasive transcatheter aortic valve replacement (TAVR). The investigators will examine the potential efficacy of (a) a motivation interviewing program, and (b) a home-based physical activity + motivational interviewing program, compared to (c) usual care + enhanced education in patients post-TAVR procedure.
This study is a multicenter cohort study including patients diagnosed with aortic valve disease during hospitalization, including aortic insufficiency and aortic valve stenosis. The primary outcome of the study was all-cause death, and the secondary outcome was cardiovascular events. Through follow-up observation, the prognostic risk factors of patients with aortic disease were evaluated, and a prognostic model was constructed to guide clinical decision-making.
The main objective of this study is to assess the preliminary safety and effectiveness of the J-Valve TF System in patients with symptomatic severe native aortic regurgitation who are judged by a multi-disciplinary heart team to be eligible for the device and to be at high risk for open surgical aortic valve replacement.
The goal of this open, prospective, multicenter study is analyze long-term outcomes of aortic/mitral valve replacement using the "UniLine" bioprosthesis in patients with acquired aortic or mitral valve diseases. Main research objectives: To analyze long-term (up to 12 years) outcome of aortic or mitral valve replacement using the "UniLine" bioprosthesis. To study the hemodynamic characteristics of normally functioning "UniLine " prostheses in the mitral or aortic valve position based on the transthoracic echocardiography data. To assess the number, type, time frames of dysfunctions of UniLine bioprostheses and the results of their treatment. To analyze the frequency of major serious adverse events associated with the "UniLine" bioprosthesis or procedure.
Rationale: Patients awaiting cardiac surgery can experience pre-procedural anxiety. This anxiety is associated with increased analgesic needs, increased risk of mortality and prolonged recovery time. Adequate patient education can help diminish pre-procedural anxiety and minimize postoperative complications. Recent studies have demonstrated that Virtual Reality (VR) can function as a useful tool to diminish pre-procedural anxiety in several medical fields. Especially 360 degree VR could familiarize patients with their clinical pathway. Nevertheless, limited to no research on the application of 360 degree VR has been conducted in the context of cardiothoracic surgery yet. Objective: The aim of this study is to explore the effects and possible benefits of 360 degree VR on pre-procedural anxiety in patients awaiting elective cardiac surgery involving a sternotomy, compared to standard forms of patient education. Study design: Single-center, randomized controlled trial Study population: Patients aged 18 or older awaiting elective cardiac surgery involving a sternotomy.
The goal of this multicenter prospective cohort study is to evaluate the long-term safety and efficacy of clinical outcomes of aortic valve replacement using the "TiAra" prosthesis with or without concomitant procedures. Main research objectives: 1. To analyze the short and mid-term (up to 3 years) outcome of aortic valve replacement using the "TiAra" prosthesis. 2. To study the hemodynamic characteristics of normally functioning "TiAra" prostheses in the aortic position, as well as the condition of the heart chambers in short and long-term period (up to 10 years) after the implantation. 3. To assess complications of the early and mid-term follow-up periods of aortic valve replacement using the "TiAra" prosthesis. This study does not presuppose implementation of comparison groups.
In addition to conventional heart valve surgery (HVS) via full-sternotomy, which is still the most prevalent therapeutic strategy to address valvular heart disease (VHD), minimally-invasive approaches evolved as safe alternatives, resulting in lower postoperative ventilation times, transfusion rates and shorter in-hospital stay. Femoral artery cannulation is traditionally performed via surgical cutdown to establish cardiopulmonary bypass during minimally-invasive HVS. To avoid groin incision associated infection and lymphocele formation, and further minimize surgical trauma, the use of percutaneous cannulation including novel endovascular closure devices increases as an alternative but remains to be investigated. The Percutaneous peRipheral cannulatiOn for Minimally-InvaSive heart valve surgEry (PROMISE) registry aims to elucidate the safety, feasibility, and effectiveness of newly developed vascular closure devices during minimally-invasive HVS. Acute intra- and perioperative complications will be evaluated according to modified definitions of the Valve Academic Research Consortium (VARC)-3. In addition, based on the initial results, the comparison of percutaneous cannulation with conventional surgical cut-down techniques is planned.
