The Sentinel Registry

Aortic Valve DiseaseTranscatheter Aortic Valve Implantation1 more

This registry is to evaluate procedural outcomes and safety outcomes of cerebral protection devices during transfemoral TAVR in real-world clinical practice. The data from this registry will be compared with the extracted data from the TP TAVR registry(NCT038262664) using Propensity Score Matching.

DIrect Oral Anticoagulation and mechaNical Aortic Valve

Aortic Valve Disease

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).

Post-market Clinical Monitoring of the Safety and Efficacy of the Aortic Valve Bioprothesis

Aortic Valve DiseaseArtificial Heart Valves

The goal of this multicenter prospective cohort study is to evaluate the long-term safety and efficacy of clinical outcomes of aortic valve replacement using the "TiAra" prosthesis with or without concomitant procedures. Main research objectives: To analyze the short and mid-term (up to 3 years) outcome of aortic valve replacement using the "TiAra" prosthesis. To study the hemodynamic characteristics of normally functioning "TiAra" prostheses in the aortic position, as well as the condition of the heart chambers in short and long-term period (up to 10 years) after the implantation. To assess complications of the early and mid-term follow-up periods of aortic valve replacement using the "TiAra" prosthesis. This study does not presuppose implementation of comparison groups.

SwissTAVI Registry

Aortic Valve Disease Mixed

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.

Aortic Valve DiseaseMitral Valve Disease

The goal of this open, prospective, multicenter study is analyze long-term outcomes of aortic/mitral valve replacement using the "UniLine" bioprosthesis in patients with acquired aortic or mitral valve diseases. Main research objectives: To analyze long-term (up to 12 years) outcome of aortic or mitral valve replacement using the "UniLine" bioprosthesis. To study the hemodynamic characteristics of normally functioning "UniLine " prostheses in the mitral or aortic valve position based on the transthoracic echocardiography data. To assess the number, type, time frames of dysfunctions of UniLine bioprostheses and the results of their treatment. To analyze the frequency of major serious adverse events associated with the "UniLine" bioprosthesis or procedure.

Calcific Aortic Valve Disease:the Role of Bacteria as Trigger of a Chronic Inflammation

Calcific Aortic Valve Diasease

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.
