Filter by:This is a prospective, observational, single-arm, multi-center registry of patients undergoing bioprosthetic aortic valve replacement with the Avalus valve. This prospective registry aims to examine the outcome and performance of surgical aortic valve replacement with the Avalus pericardial bioprosthesis.
To collect information about the management of symptomatic severe Aortic Stenosis (AS) and Aortic Regurgitation (AR) using transcatheter aortic valve replacement (TAVI).
Retrospective observational study of all patients undergoing aortic root surgery with aortic valve conservation, using the inclusion technique described by Tirone David, between January 1, 2004 and December 31, 2020, at six centers (Nantes - Rennes - Brest - Angers - Tours [two centers]). The main objective of this study is to evaluate the survival without re-intervention for aortic valve dysfunction (surgery or TAVI).
Paraprosthetic cardiac valve leaks are a progressive complication after after surgical or percutaneous heart valve replacement. These leaks can lead to heart failure and/or life-threatening hemolysis. Percutaneous closure of para-prosthetic leaks has been developed as an alternative to surgery in high-risk patients. These procedures remain technically challenging with a significant risk of failure and complications, but this risk is improved since the development of dedicated prostheses and the increased experience of the operators. The data in the literature concerning percutaneous leak closure remain limited and disparate and mostly retrospective.The impact of the procedures on the quality of life of patients is not known. Beyond the technical aspects and the follow-up of major cardiovascular events, investigators also wonder what is the impact of these procedures on the quality of life of patients. Investigators hypothesize that even a partial reduction in paraprosthetic leakage may be associated with an improvement in quality of life through reduction of transfusion needs and/or reduction of dyspnea. A prospective study is warranted to assess the technical and clinical and clinical results of these procedures, together with the evaluation of the the possible benefit on the quality of life of the patients.
Data on valve performance following ViV-TAVR has usually been obtained with the use of Doppler-echocardiography. However, some reports have shown significant discordances in the evaluation of mean transvalvular gradient between echocardiography and catheterization, with an overestimation of the real gradient with echo (vs. cath) in most cases. Thus, the incidence of procedural-device failure may be lower than that reported in the ViV-TAVR literature,
The optimal timing of surgical intervention in asymptomatic patients with severe aortic regurgitation remains controversial. As per cardiac magnetic resonance assessment, early surgical treatment will be compared with conventional guideline-based strategy in asymptomatic patients with severe aortic regurgitation.
To Evaluate the Safety and Effectiveness of Transcatheter Aortic Valve System ( Chengdu Silara Medtech Inc. ,Chengdu, China)in Patients with Severe Symptomatic Aortic Insufficiency
To evaluate the safety and performance of The Meridian® TAVR Valve in patients with severe aortic regurgitation who present at high risk for aortic valve replacement surgery.
The aorta is the principal arterial vessel arising from the left heart that transfers blood to the body. Certain genetic and familial disease processes are known to weaken the aortic wall resulting in dilation and potential rupture. These aortic complications carry high mortality (>25%) and current management is orientated towards early detection and preventive treatment. Aortic dilation can also result in aortic valve dysfunction leading to heart failure. The estimated UK incidence of aortic disease per year is around 10 per 100,000 individuals, with 2000 people per year dying from aortic complications. The 2017-2020 National Adult Cardiac Surgery Audit report identified the number of people receiving surgery for aortic dissection in Scotland is per population proportionately lower compared to England (4.6 per million per year in Scotland vs. 6.6 per million per year in England). The reasons for this are unclear but may relate to the prevalence of aortic disease or a large geographic distribution with compromised access to specialized centres. Currently surgery is recommended when the aortic diameter exceeds a certain threshold. There are several types of effective surgical procedures, but there is still limited information on their long-term outcomes and the advantage of one procedure over another. The aims of the project are firstly to determine the clinical outcomes of the surgical procedures that are currently employed in Scotland to treat proximal aortic disease and secondly to describe the prevalence and distribution of proximal aortic disease within the Scottish population. The project will be hosted by the Golden Jubilee Research Institute. Contemporary and retrospective data will be collected from all the Scottish Cardiothoracic Surgery units which are based in Glasgow, Edinburgh and Aberdeen. This will be the first study to analyse surgical outcomes for ascending aortic disease in Scotland, and the first to describe the epidemiology of aortic disease within the population. It is anticipated that the results will guide current surgical practise, and provide data to inform national service provision for the management of proximal aortic disease.
To assess whether cardiac T1 mapping for detection of myocardial fibrosis enables preoperative identification of patients at risk for early left ventricular dysfunction after surgery of aortic regurgitation.
