Filter by:Bicuspid Aortic Valve (BAV) is the most common congenital heart malformation in adults, but very little is known about the genetic causes or risk factors for adverse outcomes. Currently, it is estimated that most cases of aortic stenosis in patients less than 65 years old are caused by BAVs. BAV patients are also at high risk to develop aneurysms of the ascending aorta, which may lead to aortic dissections. Dr. Prakash and his colleagues plan to use individual genetic information to identify persons with BAV who are at high risk for complications and to customize therapies.
The purpose of this study is to assess the safety and device success of the Edwards SAPIEN 3 Transcatheter Heart Valve (S3 THV) and the Edwards Commander and Certitude Delivery Systems in patients with symptomatic, severe aortic stenosis who are indicated for aortic valve replacement.
The purpose of this study is to assess the safety and device success of the Edwards CENTERA Transcatheter Heart Valve (THV) System in patients with symptomatic, severe aortic stenosis who are indicated for aortic valve replacement.
The study is being done to determine if the Endovent pulmonary catheter kit, used for port access surgery, can be used as a passageway for a pacing wire. The study hypothesis is that the Endovent kit can be used effectively as a passageway for a pacing wire system.
The purpose of this study is to compare aspirin + clopidogrel with aspirin alone as antithrombotic treatment following transcatheter aortic valve implantation (TAVI) for the prevention of major ischemic events [myocardial infarction (MI), ischemic stroke] or death without increasing the risk of major bleeding events.
The purpose of this prospective multi-center, observational national registry in Switzerland is to obtain clinical baseline, procedural and follow-up data of all patients treated with TAVI in Switzerland and to assess short, mid- and long-term clinical outcome data of the CE approved devices. All centers in Switzerland implanting the CE approved devices for TAVI will be invited to include patients in the registry. Each site will collect baseline and procedural data as well as clinical outcome data up to five years.
The bioprosthetic aortic valve replacement is a frequent intervention because of the predominance of calcified aortic stenosis, which is the most common valvular disease, and aging of the population. International guidelines recommend anticoagulant therapy during the 3 postoperative months, but the risk-benefit ratio of anticoagulation post-operatively is questioned because of the low level of evidence available studies and their sometimes conflicting conclusions. Questionnaires sent to practitioners have highlighted discrepancies between common practices and recommendations. However, there is no analysis of actual patterns of postoperative anticoagulation after aortic valve replacement with bioprosthesis. The aim of the ARVA observatory is to establish a cohort of 600 patients enrolled in 3 months and had a bioprosthetic aortic valve replacement in one of the 22 surgical centers French.
Use of whole blood impedance aggregometry and rotational thromboelastometry can reveal useful data about platelet function and viscoelastic properties of blood clot in patients undergoing cardiac surgery. The purpose of this study is to clarify whether it is possible to predict patients on excessive risk of perioperative bleeding using whole blood impedance aggregometry and rotational thromoelastometry. Antiplatelet therapy is the cornerstone in treatment of patients with coronary artery disease. Another research goal is to determine the degree of response to antiplatelet therapy before and after surgery and to investigate whether patients by level of response to antiplatelet therapy before surgery have a higher risk of perioperative bleeding.
The Trifecta™ Durability Study was a multi-center, prospective, single-arm, post-market study conducted in Europe and Canada to collect long-term safety and performance data on the Trifecta™ valve. The Trifecta™ valve is a stented surgical aortic bioprosthesis with bovine pericardial leaflets designed for supra annular placement.
For this study, blood and tissue samples will be collected in order to perform genetic testing to help researchers gather information about this disease and how and why it affects some patients more than others.
