Portico TAVI Implant With Transfemoral Delivery System
Portico TAVI Implant With Transfemoral Delivery System
The purpose of this study is to assess the safety and effectiveness of the SJM Portico
 Transcatheter Heart Valve and the SJM TAVI Transfemoral Transcatheter delivery system in
 subjects with severe symptomatic aortic stenosis (AS).
Data will be collected at baseline, procedure, discharge, 30 days post implant, 3 months post
 implant, 6 months post implant, and 12 months post implant.
Inclusion Criteria:

 1. Subject has given written study Informed Consent for participation prior to procedure.

 2. Subject is ≥ 18 years of age or legal age in host country.

 3. Subject's aortic annulus diameter meets the range indicated in the Instructions for
 use as measured by echocardiogram (echo) or CT conducted within the past 90 days.

 4. Subject has senile degenerative aortic stenosis with echocardiography (echo) derived
 mean gradient >40mmHg or jet velocity greater than 4.0 m/s or an initial valve area of
 <1.0 cm2 (or aortic valve area index ≤ 0.6 cm2/m2). (Baseline measurement taken by
 echo within 30 days of procedure).

 5. Subject has symptomatic aortic stenosis as demonstrated by NYHA Functional
 Classification of II or greater.

 6. Subject is deemed high operable risk and suitable for TAVI per the medical opinion of
 the Subject Selection Committee (See Section 3.1 for the definition of the Subject
 Selection Committee)

 7. Subject's predicted operative mortality or serious, irreversible morbidity risk is
 <50% at 30 days.

 8. In the opinion of the Subject Selection Committee and based upon angiographic
 measurements, the subject has suitable peripheral vessels and aorta to allow for
 access of the 18 French delivery system.

 9. Subject has structurally normal cardiac anatomy.

 10. Subject is willing and able to comply with all required follow-up evaluations.

 Exclusion Criteria:

 1. Subject has a history of a cerebral vascular accident (CVA) or transient ischemic
 attack (TIA) within the past 6 months (≤180 days) of the index procedure.

 2. Subject has carotid artery disease requiring intervention.

 3. Subject has evidence of a myocardial infarction (MI) within the past 6 months (≤180
 days) of the index procedure.

 4. Subject has hypertrophic cardiomyopathy.

 5. Subject has a native aortic valve that is congenitally unicuspid, bicuspid,
 quadricuspid or non-calcified as seen by echocardiography.

 6. Subject has mitral or tricuspid valvular regurgitation (>grade III) or moderate to
 severe mitral stenosis.

 7. Subject has aortic root angulation >70 degrees (horizontal aorta).

 8. Subject has a pre-existing prosthetic valve or prosthetic ring in any position.

 9. Subject refuses blood transfusion or surgical valve replacement.

 10. Subject has left ventricular ejection fraction (LVEF) < 20%.

 11. The subject has documented, untreated coronary artery disease (CAD) requiring
 revascularization.

 12. Subject has severe basal septal hypertrophy.

 13. Subject has had a percutaneous interventional or other invasive cardiac or peripheral
 procedure ≤ 14 days of the index procedure.

 14. Subject has a history of or has active endocarditis.

 15. Subject has echocardiographic evidence of intracardiac mass, thrombus, or vegetation.

 16. Subject has hemodynamic instability (requiring inotropic support or mechanical heart
 assistance).

 17. Subject is in acute pulmonary edema or requiring intravenous diuretic therapy to
 stabilize heart failure.

 18. Subject with significant pulmonary disease.

 19. Subject has significant chronic steroid use.

 20. Subject has a known hypersensitivity or contraindication to anticoagulant or
 antiplatelet medication.

 21. Subject has renal insufficiency as evidenced by a serum creatinine > 3.0 mg/dL
 (265µmol/L) or end-stage renal disease requiring chronic dialysis.

 22. Subject has morbid obesity defined as BMI ≥ 40.

 23. Subject's iliac arteries have severe calcification, tortuosity (>two 90 degree bends),
 diameter <6mm, or subject has had an aorto-femoral bypass.

 24. Subject has ongoing infection or sepsis.

 25. Subject has blood dyscrasias (leukopenia, acute anemia, thrombocytopenia, history of
 bleeding diathesis, or coagulopathy).

 26. Subject has a current autoimmune disease that, in the opinion of the Principal
 Investigator precludes the subject from study participation.

 27. Subject has significant aortic disease, including:

 -  aortic abdominal aneurysm (AAA) ≥ 4cm

 -  thoracic aneurysm (defined as a maximal luminal diameter of 5 cm or greater)

 -  marked tortuosity

 -  significant aortic arch atheroma or narrowing of the abdominal or thoracic aorta

 -  severe tortuosity of the thoracic aorta.

 28. Subject has a pre-existing endovascular stent graft in the supra- or infrarenal aorta
 or pre-existing stent grafts in the ileo-femoral arteries.

 29. Subject has an active peptic ulcer or has had gastrointestinal (GI) bleeding within
 the past 90 days prior to the index procedure.

 30. Subject is currently participating in another investigational drug or device study.

 31. Subject requires emergency surgery for any reason.

 32. Subject has a life expectancy < 12 months.

 33. Subject has other medical, social or psychological conditions that, in the opinion of
 the Subject Selection Committee, preclude the subject from study participation.

 34. Subject is suffering from dementia or admitted to a chronic care facility which would
 fundamentally complicate rehabilitation from the procedure or compliance with
 follow-up visits.

 35. Subject has a known allergy to contrast media, nitinol alloys, porcine tissue, or
 bovine tissue.
