Description

Inclusion Criteria:

• Patient has suitable anatomy for J-Valve implantation (see anatomic exclusions below);
• Patient or the patient's legal representative has provided written informed consent;

• Active infection, including infective endocarditis;
• Liver failure (Child-C);
• Reduced left ventricular function with left ventricular ejection fraction (LVEF) <25% as measured by resting echocardiogram;

• Renal insufficiency (eGFR <25) and/or end stage renal disease requiring chronic dialysis;
• Pulmonary Hypertension (systolic pressure ≥2/3 of systemic);
• Severe Chronic Obstructive Pulmonary Disease (COPD) = requiring steroids or requiring continuous home O2
• Severe mitral or severe tricuspid regurgitation or stenosis;
• Symptomatic carotid or vertebral artery disease or successful treatment of carotid stenosis within six weeks of treatment;
• Cardiogenic shock manifested by low cardiac output, vasopressor dependence, or mechanical hemodynamic support;
• Recent (within 6 months of treatment) cerebrovascular accident (CVA) or transient ischemic attack (TIA);
• Active gastrointestinal (GI) bleeding that would preclude anticoagulation;
• Untreated multivessel coronary artery disease with a Syntax score >22 and/or unprotected left main coronary artery;
• Evidence of acute myocardial infarction within 1 month of intended procedure;
• PCI within 30 days of intended procedure;
• Estimated life expectancy of less than 24 months due to associated (excluding cardiac) co-morbid conditions;
• Left Ventricular Assist Device (LVAD) dependent;
• Participating in another study that may influence the outcome of this study;
• Need for emergency surgery for any reason;
• Previous aortic bioprosthesis or mechanical implant.

Anatomic Exclusion Criteria:

• Ascending Aortic diameter >5 cm;
• Aortic Annulus Perimeter <57 mm or >104 mm;
• Access vessel minimum diameter <5.5 mm;
• LVEDD >75 mm;
• Bicuspid aortic valve disease;
• Congenital univentricle or other condition that, in the opinion of the investigator and/or consulting physician, may constitute an unwarranted surgical risk.
• Abdominal aortic aneurysm ≥ 4.0 cm;
• Aorto-iliac disease requiring intervention to facilitate delivery of access sheath;
• Excessive tortuosity of delivery system pathway, defined as severe tortuosity of multiple vessels including iliofemoral, descending aorta, ascending aorta, aortic arch, and aortic angle >80⁰. In most cases, this exclusion will be identified and assigned following review by the multi-disciplinary Screening Committee.
