Filter by:Transcatheter aortic valve replacement (TAVR) has became an important treatment of severe aortic stenosis (AS). Several randomized clinical trials showed that TAVR was non-inferior or superior to surgical aortic valve replacement (SAVR). However, many different issues have emerged: TAVR in younger patients? valve leaflet thrombosis? transcatheter valve durability? coronary reaccess after TAVR? TAVR in bicuspid aortic valve? TAVR in aortic regurgitation? etc. Hence, a prospective, multicenter database is created to provide the real-word data for these questions.
This clinical study is a prospectivećsingle arm and exploratory study, to explore the feasibility and safety of MitrAssist TRISKELE® transcatheter aortic valve system in the treatment of patients with severe aortic stenosis.
Non-randomized, open label, non-interventional, multicenter registry to describe risk factors, management strategies, and clinical outcomes in patients undergoing Valve in Valve (ViV) transcatheter aortic valve implantation (TAVI) in a previously implanted Trifecta or Epic valve using retrospective registry data from large volume centers
The objective of the study is to evaluate the safety, effectiveness, and performance of the EMBLOK EPS during TAVR by randomized comparison with a commercially available embolic protection device. The targeted study population consists of patients meeting FDA-approved indications for TAVR with commercially available transcatheter heart valve systems. This prospective, multicenter, single-blind, randomized controlled trial will enroll up to a total of 532 subjects undergoing TAVR at up to 30 investigational sites in the United States. All subjects will undergo clinical follow-up (including detailed neurological assessments) in-hospital and at 30 days.
This registry is to evaluate procedural outcomes and safety outcomes of cerebral protection devices during transfemoral TAVR in real-world clinical practice. The data from this registry will be compared with the extracted data from the TP TAVR registry(NCT038262664) using Propensity Score Matching.
Aortic stenosis (AS) is the most common valvular heart disease in the developed world. Once symptomatic, untreated patients have a poor prognosis with five-year survival rate of 25%. Once at an advanced stage, AS will lead to the development of left ventricle hypertrophy, and eventually heart failure and death. At-present, there is no effective medical therapy for aortic stenosis. Current management of patients with AS consists of 'watchful waiting'. Valve replacement is needed when these patients (often acutely) become symptomatic. Recent studies have shown that inflammatory processes with similarities to atherosclerosis play an important role in AS. Therefore, we hypothesize that treatment with anti-inflammatory therapy, in the form of colchicine, could reduce the progression of AS. If positive, this trial will be the first to provide a potential therapeutic option for millions of people world-wide with AS.
This is an adaptive Phase 2/3 multicenter, double-blind, placebo-controlled, randomized, parallel, 3 arm study to evaluate the efficacy and safety of DA-1229 compared to placebo in patients with calcific aortic valve disease with mild to moderate aortic stenosis. There are 3 arms in this study to which patients will be randomized in a ratio of 1:1:1 to receive the DA-1229 or placebo orally once daily for a period of 104 weeks . the 3 arms are: placebo, DA-1229 5mg GroupDA-1229 10 mg Group. The study will have three phases: Screening Period (up to 4 weeks), Treatment Period (104 weeks), and Follow-Up Period (2-4 weeks). Total Study Duration is112 Weeks.
The objective of this study is to quantify the amount of debris captured by the SENTINEL transcatheter cerebral embolic protection (TCEP) device in patients undergoing valve in valve transcatheter aortic valve replacement (VIV TAVR) with bioprosthetic valvular fracture (BVF)
This is a prospective, randomized study that is studying the rate of red blood cell (RBC) transfusion rates after planned heart (cardiac) surgery. The study will be conducted at Barnes-Jewish Hospital. Cardioplegia refers to the method of stopping (arresting) the heart in order to perform heart surgery. However, cardioplegia has also come to refer to the solution to achieve cardiac arrest as well as the machinery in which to deliver the solution. This study will investigate our current Standard Cardioplegia (diluted 4:1 blood cardioplegia) versus Microplegia (undiluted blood cardioplegia) to determine if Microplegia reduces peri-operative blood transfusion rates as compared to Standard Cardioplegia. All forms of cardioplegia will be delivered using the MPS2 Microplegia delivery machine by Quest Medical, Inc. Patients will be randomized to receive undiluted microplegia or standard 4:1 cardioplegia. The patient and the surgeon will be blinded to the randomization. Patients will be followed for 30 days post-operatively (or until their initial standard of care post-operative follow up visit with cardiac surgery if that appointment falls outside of the 30 day post-operative window) for the development of any adverse events as well as documentation of blood products given. We will draw one tube of blood for troponin levels at four time points; 1 draw before surgery (this may be done during the intraoperative period), and 3 draws post-operatively: ICU arrival, 12 hours post-ICU arrival and 24 hours post-ICU arrival. This is to closely monitor the patient for any heart tissue injury.
Aortic valve disease (AVD) is the most common and age-related mortality in elderly patients with valvular heart disease (VHD). Although transcatheter aortic valve replacement (TAVR) has been recommended at a higher level in foreign guidelines, there are still many high-risk and severe elderly patients with VHD who have not received effective treatment because of many complications and untimely medical treatment. Different from Europe and the United States, the majority of patients with bicuspid aortic valve are in China, and the calcification is more serious. The current clinical evaluation system and treatment guidelines can not be effectively applied to the high-risk and complex elderly patients. Therefore, the investigators should train and set up a valvular heart disease team, explore the technical difficulties of TAVR treatment in such patients, establish emergency TAVR operation mechanism, build a clinical evaluation system for high-risk and complex elderly patients with aortic valve disease in China, evaluate the curative effect periodically and further optimize the treatment strategy, so as to improve the quality of life and the meaning of life cycle of elderly patients with VHD in China Great significance.
