Filter by: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)
The ASCEND post-market clinical follow-up study is undertaken to evaluate safety and clinical performance of the On-X Ascending Aortic Prosthesis (AAP) used in surgical aortic valve replacement.
TAVR patients exhibiting post-procedural residual AR had higher mortality and hospitalization rates due to heart failure, with the extent of this association increasing proportionally to the severity of the regurgitation. Optimizing transcatheter valve performance by intra-procedural hemodynamic evaluation of AR and residual transvalvular gradient remains of high clinical importance.
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.
Cardiac rehabilitation (CR), particularly regular exercise, can improve the cardiopulmonary function, exercise capacity, and quality of life for patients undergoing transcatheter aortic valve implantation (TAVI). Consequently, the patients after TAVI will be enrolled in our randomized controlled trial to demonstrate if the moderate-intensity continuous training (MICT) can improve the cardiopulmonary function compared with the control group after receiving treatment for 12 weeks. Moreover, we will provide new insights regarding whether cardiac systolic function or cardiac diastolic function is mainly improved after regular exercise for TAVI patients. As a result, the principal hypothesis of our study is that MICT will improve the cardiopulmonary function and can extremely affect the cardiac diastolic function of patients with TAVI after the implementation of exercise for 12 weeks.
The purpose of this observational registry is to report real-world safety and performance of VeriSight for ultrasound guided ICE imaging in percutaneous cardiac intervention procedures when used in standard clinical practice.
The general rules of antibiotic prophylaxis in surgery or interventional medicine include the choice of an antibiotic active on the bacteria most frequently encountered in surgical site infections. This antibiotic must cover, the bacteria present on the skin and recognized as responsible for surgical site infections. The aim of this study is to identify bacteria found in skin flora in the inguinal region of patients undergoing Transcatheter Aortic Valve Implantation (TAVI). Flora found will allow to evaluate the impact of skin preparation and antibiotic prophylaxis protocols as they are currently practiced.
The overall project aim is to study outcomes following aortic valve replacement with either mechanical valves or bioprostheses by retrieving data from the main social security carriers in Austria for the years 2010-2018.
