Filter by:Patients undergoing transcatheter valvular interventions will be prospectively included into the present registry. Baseline, procedural and follow-up data will be collected and analyzed to adress various issues in the field of percutaneous valvular interventions.
The objective of this registry is the characterization of patients with atrial fibrillation (AF) and/ or atrial flutter (AFL) with confirmed VHD who are prescribed edoxaban in a real life clinical setting.
This is a observational、multicenter, prospective cohort study for adults with significant VHD. The purposes of this study were to evaluate the etiology、clinical characteristics、treatment modalities, and outcomes of patients with VHD；also to set up registration system of adult VHD in China, to build a database of Chinese adult VHD, to establish a web-based international standard data acquisition system for VHD and a multicenter clinical research platform. The results of the study will provide a basis for the future national health policy for prevention and treatment of adult VHD.
To compare the efficiency and safety between gene-oriented group and standard care group during 90 days of initial warfarin-treatment for requiring anticoagulation patients with valve replacement or atrial fibrillation with or without valvular heart disease。
The objective is the development and validation of morphological markers informative of aortic dilatation in order to improve the precision of the risk of aneurysm of the thoracic aorta and of acute aortic syndrome for patients with bicuspid aortic valve (BAV). The primary objective of this study is to demonstrate a correlation between the aortic local pulse wave velocity (PWV) measured with MRI and the progression of the thoracic aorta diameters measured by MRI after a follow-up of 2 years.
Pre-habilitation programs that combine physical training, nutritional support and emotional reinforcement have demonstrated efficacy as presurgical optimization strategies in the context of digestive surgery. The experience in patients at risk for cardiac surgery, one of those associated with higher morbidity and mortality, is anecdotal. Main objective: to evaluate the feasibility, efficacy and cost-effectiveness of a pre-habilitation program for the improvement of preoperative functional capacity in high-risk and intermediate risk groups for cardiac surgery and its impact on the reduction of postoperative complications (primary endpoint). Secondary objectives: (i) in-hospital stay; (ii) symptoms, quality of life, (iii) evaluation of information and communication technologies (ICT) as a support for the pre-habilitation, and (iv) design and validation of indicators for a future large-scale implementation of this type of intervention. Design: Subproject: #1: Prospective study of the efficacy of prehabilitation in heart transplant candidates during the study period. The results will be compared with historical records; #2: Randomized controlled trial with a 1:1 ratio to assess the efficacy of prehabilitation in patients undergoing elective coronary revascularization or valve replacement surgery. Subjects: Subproject #1: 40 patients candidates for heart transplantation. Subproject #2: 80 patients in the prehabilitation group and 80 controls in which a conventional treatment will be performed. Intervention: (i) personalized supervised resistance training, and (ii) program to promote physical activity and healthy lifestyles. The overall duration of the intervention is estimated to be at least 4-6 weeks (variable in each subproject). The support with ICTs will be a significant aspect of the program in which the adaptation of the personal health folder of Catalonia (Cat@SalutLaMevaSalut) will be fundamental.
The diagnosis of valvular heart disease (VHD), or its absence, invariably requires cardiac imaging. A familiar and inexpensive tool to assist in the diagnosis or exclusion of significant VHD could both expedite access to life-saving therapies and reduce the need for costly testing. The FDA-approved Eko Duo device consists of a digital stethoscope and a single-lead electrocardiogram (ECG), which wirelessly pairs with the Eko Mobile application to allow for simultaneous recording and visualization of phono- and electrocardiograms. These features uniquely situate this device to accumulate large sets of auscultatory data on patients both with and without VHD. In this study, the investigators seek to develop an automated system to identify VHD by phono- and electrocardiogram. Specifically, the investigators will attempt to develop machine learning algorithms to learn the phonocardiograms of patients with clinically important aortic stenosis (AS) or mitral regurgitation (MR), and then task the algorithms to identify subjects with clinically important VHD, as identified by a gold standard, from naïve phonocardiograms. The investigators anticipate that the study has the potential to revolutionize the diagnosis of VHD by providing a more accurate substitute to traditional auscultation.
This is a pilot study to determine the hemodynamic effects when hydroxocobalamin vs methylene blue is administered during cardiopulmonary bypass in patients at risk of vasoplegia by measuring mean arterial pressure (MAP), systemic vascular resistance (SVR) and vasopressor requirement.
The main purpose of this study is to define the complex genetic and pathogenic basis of thoracic aortic aneurysm (TAA) and other forms of aortopathy and/or aortic valve disease by identifying novel disease-causing genes and by identifying important genetic modifiers for aortic and aortic valve disease severity.
This is a randomized clinical trial, double-blind, placebo-controlled study with the goal to assess the influence of using N-AcetylCysteyn (NAC) for prevention of AKI (Acute Kidney Injury) in post operatory of valve replacement until their discharge or death
