Pivotal Study of the Vienna Transcatheter Self Expandable Aortic Valve SE System

Exclusion Criteria39

• Cardiovascular System:
• Patient has a congenital unicuspid or bicuspid aortic valve or non-calcified valves.
• Evidence of an acute myocardial infarction (MI) ≤ 30 days prior to screening or IMD implantation (defined as Q-wave MI or non-Q-wave MI with total CK elevation ≥ twice normal in the presence of CK-MB elevation and/or troponin elevation).
• Patient has had a cerebrovascular stroke or TIA within the past 90 days implantation prior to screening or valve implantation.
• Patient has a hypertrophic obstructive cardiomyopathy.
• History of any therapeutic invasive cardiac procedure (including balloon aortic valvuloplasty) within 30 days prior to screening or IMD implantation (except for pacemaker implantation which is allowed).
• Untreated clinically significant coronary artery disease requiring revascularization at the screening visit.
• Severe left ventricular dysfunction with left ventricular ejection fraction (LVEF) < 20% by echocardiography, contrast ventriculography, or radionuclide ventriculography.
• Patient with cardiogenic shock manifested by low cardiac output and hemodynamic instability and vasopressor dependence, or mechanical hemodynamic support
• Patients with clinically significant conduction abnormalities (clinically significant sinus bradycardia, sinus block or pauses, clinically significant atrioventricular (AV)-block >I) at screening and at time of IMD implantation.
• Patient has severe peripheral vascular disease:
• including aortic aneurysm defined as maximal luminal diameter > 5 cm or with documented presence of thrombus, marked tortuosity, narrowing of the abdominal aorta, severe unfolding of the thoracic aorta or thick \[> 5 mm\], protruding or ulcerated atheroma in the aortic arch) or
• symptomatic carotid or vertebral disease or successful treatment of carotid stenosis within 30 days prior to screening or IMD implantation.
• Patient with iliofemoral vessel characteristics that would preclude safe passage of the introducer (both sides), as analyzed by a core lab:
• severe calcification,
• severe tortuosity (> two 90-degree bends),
• diameter < 6 mm, in patients with acceptable levels of calcification and acceptable levels of tortuosity
• diameter < 5.5, in patients with no calcification and no significant tortuosity, OR
• subject has had an aorto-femoral bypass
• Patient with active bacterial endocarditis within 6 months prior to screening or IMD implantation.
• Patient has (echocardiographic/ CT and/or MRI) evidence of intra-cardiac mass, thrombus or vegetation.
• Patient has a pre-existing prosthetic heart valve in any position (Note: mitral ring is not an exclusion).
• Patient has severe mitral regurgitation, severe aortic regurgitation or severe tricuspid regurgitation, moderate or severe mitral stenosis.
• Patient has a need for emergency surgery for any reason at time of screening or IMD implantation.
• General:
• Any condition considered a contraindication for placement of a bioprosthetic valve (e.g. patient with contraindication to oral antiplatelet therapy)
• Patient with renal insufficiency (eGFR < 30 ml/min per the Cockcroft-Gault formula) and/ or renal replacement therapy and/ or has serum creatinine level > 3.0 mg/dL or 265 µmol/L replacement therapy at the time of screening
• Patient with significant pulmonary disease (FEV1 < 30%) or currently on home oxygen
• Severe pulmonary hypertension (e.g., pulmonary artery systolic pressure ≥ 60 mmHg)
• Patients with evidence of an active systemic infection or sepsis.
• Patient has a known hypersensitivity or contraindication to contrast media, bovine tissue, nitinol (titanium or nickel), contraindication to oral antiplatelet therapy (aspirin, ticlopidine or clopidogrel) or heparin.
• Patient has a haemoglobin < 9 g/dL, platelet count < 50,000 cells/mm3 or > 700.000 cells/mm3, or white blood cell count < 1.000 cells/mm3, history of bleeding diathesis or coagulopathy
• Patient has peptic ulcer disease or history of gastrointestinal bleeding within the 3 months prior to screening or IMD implantation.
• Patient refuses blood transfusions.
• Patient has a life expectancy of less than 12 months due to non-cardiac, co-morbid conditions based on the assessment of the investigator at the time of enrolment (i.e. the time of informed consent).
• Patient is pregnant or breast feeding.
• Severe dementia (resulting in either inability to provide informed consent for the study/procedure, prevents independent lifestyle outside of a chronic care facility, or will fundamentally complicate rehabilitation from the procedure or compliance with follow-up visits).
• Other medical, social, or psychological conditions that in the opinion of the Investigator precludes the patient from appropriate consent or adherence to the protocol required follow-up exams.
• Patient is currently participating in another investigational drug or device study that has not reached its primary endpoint (excluding observational studies).
