Eligibility
Key inclusion criteria
1. Patient must be at least 70 years of age or older, and meets all of the criteria
below.
2. Patient has documented calcified native aortic valve stenosis, defined with an initial
aortic valve area (AVA) of <1.0 cm2 (or AVA index of <0.6 cm2/m2), and a mean pressure
gradient >40 mmHg or a jet velocity >4 m/s, as measured by echocardiography.
3. The patient is considered at high risk for surgical aortic valve replacement with an
STS (Society of Thoracic Surgeons) score =8% or a EuroSCORE =20%, or documented
multidisciplinary heart team agreement that the patient is at high risk for surgery
due to frailty and/or coexisting comorbidities.
4. Symptomatic aortic valve stenosis with New York Heart Association (NYHA) Functional
Class = II.
5. Patient has a documented aortic annulus size between 19 and 22 mm (able to accommodate
the 23 mm Lotus™ Valve). Pre-procedure measurement by transthoracic echocardiography
(TTE) is required. Other imaging modalities (e.g., transesophageal echocardiography
(TEE), CT scan) can be used in an adjunctive manner.
6. Patient (or legal representative) understands the trial requirements and the treatment
procedures, and provides written informed consent.
7. Patient agrees and is capable of returning to the study hospital for all required
scheduled follow up visits.

Key exclusion criteria
1. Patient has a congenital unicuspid or bicuspid aortic valve.
2. Patient with an acute myocardial infarction (MI) within 30 days of the index procedure
(defined as Q wave MI, or non-Q wave MI with total creatine kinase (CK) elevation =
twice normal in the presence of CK-MB elevation and/or troponin level elevation (WHO
definition)).
3. Patient has had a cerebrovascular accident (CVA) or transient ischemic attack (TIA)
within the past 6 months, or has any permanent neurologic defect prior to study
enrollment.
4. Patient is on dialysis or has serum creatinine level >3.0 mg/dL.
5. Patient has a pre-existing prosthetic heart valve (aortic or mitral) or a prosthetic
ring in any position.
6. Patient has >2+ mitral regurgitation or >2+ aortic regurgitation (ie., patient cannot
have more than moderate mitral or aortic regurgitation).
7. Moderate to severe pulmonary hypertension (PA systolic pressure >60 mm Hg) as assessed
by transthoracic echocardiography.
8. Patient has a need for emergency surgery for any reason.
9. Patient has a history of endocarditis within 12 months of index procedure or evidence
of an active systemic infection or sepsis.
10. Patient has echocardiographic evidence of intra-cardiac mass, thrombus or vegetation.
11. Patient has Hgb <9 g/dL, platelet count <100,000 cells/mm3 or >700,000 cells/mm3, and
white blood cell (WBC) count <3,000 cells/mm3.
12. Patient is receiving chronic (=72 hours) anticoagulation therapy (e.g., heparin,
warfarin) and who cannot tolerate concomitant therapy with aspirin and clopidogrel
(patients who require chronic anticoagulation must be treated with either aspirin or
clopidogrel).
13. Patient has active peptic ulcer disease, gastrointestinal (GI) bleed within the past 3
months, other bleeding diathesis or coagulopathy or will refuse transfusions.
14. Patient is contraindicated for transesophageal echocardiography (TEE).
15. Patient has known hypersensitivity to contrast agents that cannot be adequately
pre-medicated, or has known hypersensitivity to aspirin, all thienopyridines, heparin,
nickel, titanium, or polyurethanes.
16. 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 enrollment.
17. Patient has other cardiac devices or hardware with which the study device will
interfere with device placement (per physician judgment).
18. Patient has hypertrophic obstructive cardiomyopathy.
19. Patient has any therapeutic invasive cardiac procedure within 30 days prior to the
index procedure.
20. Untreated clinically significant coronary artery disease requiring revascularization.
21. Patient has documented left ventricular ejection fraction (LVEF) <30%.
22. Patient is in cardiogenic shock or has hemodynamic instability requiring inotropic
support or mechanical support devices.
23. Patient has severe peripheral vascular disease (including aneurysm defined as maximal
luminal diameter >5cm or with documented presence of thrombus, marked tortuosity,
narrowing of the abdominal aorta, severe unfolding of the thoracic aorta or thick
(>5mm), protruding or ulcerated atheroma in the aortic arch) or symptomatic carotid or
vertebral disease.
24. Patient has a femoral artery lumen of <6.0 mm or severe iliofemoral tortuosity or
calcification that would prevent safe placement of the introducer sheath.
25. Current problems with substance abuse (e.g. alcohol, cocaine, heroin, etc).
26. Patient is participating in another investigational drug or device study that has not
reached its primary endpoint.
27. Patient has preexisting untreated conduction system disorders: Type II second-degree
atrioventricular (AV) block, bifascicular or trifascicular block.
