Filter by:The overall project aim is to study outcomes following aortic valve replacement with surgically implanted bioprostheses or TAVI by retrieving data from the main social security carriers in Austria for the years 2010-2020.
This is a prospective, randomized, comparative, clinical trial conducted by Wuhan Union Hospital that aims to evaluate the efficacy and safety of pioglitazone compared to placebo in patients with calcific aortic valve disease with mild aortic valve stenosis.
This is a prospective, randomized, comparative, clinical trial conducted by Wuhan Union Hospital that aims to evaluate the efficacy and safety of folic acid compared to placebo in patients with calcific aortic valve disease with mild aortic valve stenosis.
In patients with severe aortic stenosis (AS) undergoing transcatheter aortic valve implantation (TAVI) minimal evidence is available for invasive hemodynamic monitoring and no evidence for tools able to measure traditionally invasive parameters non-invasively for peri-procedural guidance and post-interventional management. The aim of this study is to evaluate the effectiveness and safety of a non-invasive hemodynamics monitoring tool called ClearSight for monitoring during TAVI procedures compared with standard invasive measurements.
Aortic valve bicuspid disease is the most common congenital heart disease. It affects 0.5-2% of the population and is associated with an increased risk of developing aortic or ascending aortic valve complications. There is no agreement regarding the opportunity for a "prophylactic" simultaneous aortic valve replacement in the case of mild or moderate aortic valve disease in the bicuspid valve, in patients with an indication for replacement of the ascending aorta due to an aneurysm involving its supra-coronary tract. The aim of this study is to evaluate the long-term evolution of mild and moderate aortic valve disease in untreated bicuspid valve during supracoronary ascending aortic replacement surgery at our institution.
Calcific aoric valve disease (CAVD) is extremely common worldwide, affecting almost 50% of the population over 85 years of age, with a lethality higher than 50% at 2 years for symptomatic patients, unless aortic-valve replacement is performed. CAVD is characterized by slowly progressive fibro-calcific remodelling of the valve leaflets causing aortic stenosis. The spectrum of the disease progression starts with leaflet degeneration and progresses from early lesions to valve stenosis/obstruction, which is initially mild to moderate but eventually becomes severe. Risk factors for CAVD partly overlap those for atherosclerosis but also intake age-related tissue changes and effects of comorbiditiies (e.g. renal failure) in the overall complex mechanisms of valve leaflet degeneration, which is, at present, unpreventable, leaving aortic valve repair the only treatment option for severe aortic stenosis. In the first phase of the disease the valve becomes thickened and mildly calcified, then the disease evolves to severe valve calcification with impaired leaflet motion and vast blood flow obstruction. Calcific AS valves show advanced osteogenic metaplasia with the presence of osteoblast-like cells and chondrocytes associated with dense inflammatory infiltrates. Bacteria have been detected in the absence of diagnosis of acute infective endocarditis, but their role is still unknown. Different bacterial species (C. acnes (59%), E. faecalis (16%), S. aureus (15%), and S. pyogenes (10%)) have been typed and intramural bacterial colonization has been observed in patients with calcified structural valvular heart disease. Indeed, it has been recently demonstrated that bacterial infections can directly affect osteoblast differentiation/activation. The Authors hypothesized that a subclinical or latent valvular bacterial infiltration facilitates a chronic inflammation and contributes to accelerated structural valve degeneration. An interdisciplinary team has been established to investigate the infective, biochemical and structural features of calcific aortic valve disease.
Evaluation of the safety and efficacy of early discharge (24 hours) after transfemoral transcatheter aortic prosthesis implantation (TAVI).
The goal of this interventional, single-center study is to demonstrate if there is a change in the coronary ostia height after surgical aortic valve replacement and if it depends on the type of prosthesis or surgical technique used. The study involves patients undergoing elective surgical aortic valve replacement with a bioprosthesis. Participants enrolled will undergo a CT scan before and after surgery (at least 90 days after surgery) to analyze coronary ostia height.
DIAMOND study is a national, multicentre, randomized, parallel-group, open label study in patients (aged ≥18 years) with mechanical aortic valve at least 7 days after cardiac surgery. Experimental group: Patients treated with apixaban 5 mg twice daily (BID) Active Comparator group: Patients treated with warfarin with an objective of INR target of 2.5 (range: 2.0-3.0) The Primary objective is To demonstrate that antithrombotic treatment with apixaban is non-inferior to warfarin (INR target range 2.0 - 3.0) in patients with mechanical heart valve implanted in the aortic position for at least 7 days for the primary net clinical benefit endpoint of ischemic outcomes (death, myocardial infarction, stroke, systemic embolism and valve thrombosis) and bleeding (ISTH major and non-major clinically relevant bleeding).
The goal of this study is to investigate whether patient-tailored follow-up for patients treated with transcatheter aortic valve implantation (TAVI) can prevent re-hospitalisation and improve quality of life compared with the standard follow-up program. The rationale of this study is the persistently high rate of re-hospitalisation after TAVI, which increases the risk of mortality and diminishes the patient-evaluated quality of life. Our hypothesis is that patient-tailored follow-up for patients treated with TAVI will reduce the rate of re-hospitalisation after the TAVI-procedure and improve quality of life. The primary endpoints are the rate of re-hospitalisation within 90 days of the procedure and quality of life adjusted life years at 90-day follow-up.
