Filter by:This study aimed to evaluate incidence, prognosis and predictive factors of new-onset of persistent left bundle branch block (LBBB) after rapid-deployment aortic valve replacement (RD-AVR) with the IntuityTM bioprosthesis. It was an observational, retrospective and single-center study. Two hundred and seventy-four consecutive patients without any baseline ventricular conduction disorder or previous permanent pacemaker or defibrillator implantation who underwent RD-AVR with the IntuityTM valve were included. Twelve-lead electrocardiogram and transthoracic echocardiography were performed preoperatively, postoperatively, at discharge, 1-month, and 1-year. Incidence, prognosis and predictive factors of new-onset of persistent LBBB were evaluated.
Prospective, multicenter, randomized trial.
Prospective Cohort Study aims at elaborating the outcomes of the Tricuspid Reconstruction of Aortic valve leaflets using autologous pericardium (Ozaki procedure) in the adult and paediatric patients. A very promising technique with the potential benefits of dodging oral anticoagulation, foreign material, and suitable for patients with small aortic annuli and in infectious endocarditis. Performing hemodynamic evaluation, assess the clinical implementation and report preliminary results at follow up .
Multicenter, global, prospective, non-randomized, interventional, post-market trial. All subjects enrolled will receive an Abbott Valved Graft device.
Investigators plan to characterize systemic inflammation and circulating immune cells in participants with moderate and severe calcific aortic valve disease and matched healthy controls.
The objective of this study is to compare surgical outcomes between patients who underwent valve replacement with and without the help of the automated annular suturing technology. In addition, data of the early and intermediate postoperative period will be collected within routine clinical follow-up in order to assess morbidity and mortality as well as echocardiographic parameters.
The CAvEAT study is a not for profit, international, multicenter study aimed to assess the feasibility of selective coronary angiography (CA) after Transcatheter Aortic Valve Implantation (TAVI), to investigate predictors of successful selective cannulation (anatomical, technical, etc.) and to investigate if there is a significant difference among different type of transcatheter valves in selective coronary cannulation.
Background Calcification of the aortic valve affects more than 26% of adult patients over 65 years of age and is the main indication for valve replacement in the United States of America. Previous evidence shows that aortic valve calcification is an active biological process associated with inflammation. The only actual treatment for severe aortic stenosis is surgical aortic valve replacement (AVR). The materials with which the different types of prostheses are manufactured could induce inflammation per se. Biological prostheses, an incomplete cell removal process and therefore, the presence of residual proteins of animal origin, could induce the immune system's response. In the manufacturing bioprosthesis at the "Ignacio Chávez" National Institute of Cardiology (INC), an evaluation was carried out in the early, and late post-surgical period, it was shown that the inflammatory response after six months is similar to that produced by mechanical prosthesis. This study's main objective is to evaluate the inflammatory response in patients with post-operated AVR due to biological or mechanical prosthetic valve through different plasma biomarkers in long-term follow-up. Research question What is the inflammatory response and calcification in patients who undergo aortic valve replacement for a manufactured prosthesis at the "Ignacio Chávez" National Institute of Cardiology in the long-term follow-up? Hypothesis Manufactured bioprostheses at the "Ignacio Chávez" National Institute of Cardiology show a similar or lower inflammatory response to imported bioprostheses or mechanical prostheses associated with less valve dysfunction and more outstanding durability.
Common barriers to receiving appropriate guideline-driven care for patients with severe aortic stenosis include referral biases by primary care providers (lack of provider education), patient comorbidities (degree of fragility), as well as psychosocial issues and cultural barriers. Additionally, race, ethnicity, socioeconomic status (SES) and education level are shown to be persistent barriers to accessing healthcare services and healthcare systems, creating a significant practice gap between various patient populations. The most recent transcatheter valve therapies (TVT) registry data show that >94% of TAVR recipients are Caucasian, followed by less than 4% of African-Americans and Hispanics, respectively. There is a critical need to understand the barriers to treatment and care among severe aortic valve disease patients of disparate groups. This study is a multi-center, retrospective and prospective cohort study of patients diagnosed with severe aortic stenosis. Additionally, we will be surveying referring primary care providers, cardiologists and cardiovascular surgeons to assess their current referral practices for patients with severe aortic stenosis.
