Filter by:This is a prospctive, unrandomized multicentric registry which will enrol patients with an indication for aortc valve replacement combined with myocardial reperfusion (CABG). The registry will collect patient specific baseline data and established risk scores (Logistic Euroscore I & II, STS-Score, KBA Score) to enable us to make an estimate about the perioperative risks.
The PROTEMBO SF Trial is a prospective, observational, multi-center, intention-to-treat study of the safety and feasibility of the ProtEmbo Cerebral Protection System in subjects with severe symptomatic native aortic valve stenosis indicated for TAVR.
To evaluate the safety and effectiveness of the SAPIEN XT (Edwards Lifesciences, Irvine, California) transcatheter heart valve implantation (TAVI) in Chinese patients with symptomatic severe calcific aortic stenosis who are considered at high risk for surgical valve replacement.
This trial is to compare the efficacy of NOAC(Novel Oral Anticoagulants) with edoxaban vs. dual antiplatelet therapy (DAPT) for prevention of leaflet thrombosis (documented by cardiac CT imaging) and cerebral embolization (documented with brainDiffusion-weighted (DW) magnetic resonance (MR) imaging) in patients without an absolute indication for chronic oral anticoagulation (OAC) after successful transcatheter aortic valve replacement(TAVR).
This study is being performed in patients who have undergone transcatheter aortic valve replacement (TAVR) for aortic stenosis. The goal is to obtain pilot and feasibility data on a novel post-procedure rehabilitation strategy, including a daily activity goal using a fitness tracking device (Fitbit Alta HR) and in-home resistance training exercises targeting muscles related to activities of daily living. We will evaluate the effect of these interventions on physical performance and several quality of life domains.
Prospective cohort study to test the hypothesis that patients identified with severe aortic stenosis are under-diagnosed and under-treated. Such patients shall be identified by auscultation or target echocardiography during flu vaccination. The hypothesis is that this will increase detection of aortic stenosis in the community.
Transcatheter aortic valve implantation (TAVI) is well established, and can improve clinical outcomes of patients with severe aortic valve stenosis (AS) who are inoperable or have high surgical risk. Although the rates of periprocedural bleeding events are lower in TAVI compared to those in surgical aortic valve replacement, those in TAVI still remains high. In addition, current guideline recommended the dual antiplatelet (DAPT), clopidogrel plus aspirin, for a 3- to 6-month period after TAVI, however no evidences supports this approach. The antithrombotic regimen in patients undergoing TAVI is needed to be established. To establish the antithrombotic regimen in patients undergoing TAVI, 1. the investigators assess the changes in platelet thrombus formation and white thrombus formation in patients undergoing TAVI measured by Total Thrombus Formation Analysis System (T-TAS). 2. the investigators analyze plasma microRNAs, and shear stress by using computational fluid dynamics (CFD) to clarify the mechanistic factors regarding those changes.
Aortic stenosis is a common heart valve disease and due to the growing elderly population the prevalence is increasing. The disease is progressive with increasing calcification of the valve cusps. A few attempts with medical preventive treatment have failed, thus presently the only effective treatment of aortic stenosis is surgery. This study will examine the effect of menaquinone-7 (MK-7) supplementation on progression of aortic valve calcification (AVC). The investigators hypothesize that MK-7 supplementation will slow down the calcification process.
To assess the safety and effectiveness of the SAPIEN XT transcatheter heart valve in patients with a failing surgical aortic bioprosthetic valve.
The purpose of this trial is to determine the safety and effectiveness of the Edwards SAPIEN 3 transcatheter heart valve and delivery systems which are intended for use in patients with symptomatic, calcific, severe aortic stenosis, and are in high risk.
