All Women Comparing Self-expanding ALLEGRA Valve to Any Other Balloon-expandable Valve
All Women A Multicenter Randomized Clinical Trial Comparing Self-expanding ALLEGRA Valve to Any Other Balloon-expandable Valve in a Women Population
Study Overview

Conditions
Intervention / Treatment
Detailed Description
Study is aimed to demonstrate that the self-expandable Allegra transcatheter aortic valve implantation (TAVI) system provides lower mean gradient assessed by Transthoracic Echo (TTE) at 30 days post procedure, compared to balloon-expandable valve systems in a female patient population with symptomatic severe aortic stenosis.
Patients in both arm will receive anticoagulants according to routine practice of the hospital.
Patients will be followed-up until 1 year after the procedure.

Accepts Healthy Volunteers
Description
Inclusion Criteria:
- Female sex
- Age ≥ 75 years (according to ESC/EACTS, Guidelines for the management of valvular heart disease)
- Severe calcific aortic valve stenosis defined as follows: high-gradient aortic stenosis (mean pressure gradient across aortic valve > 40 mmHg or peak velocity > 4.0 m/s) Symptomatic aortic valve stenosis with New York Heart Association (NYHA) Class ≥II
- ECG-gated Multi-Slice Computed Tomographic (MSCT) measurements determined an aortic annulus perimeter-derived average diameter >19 mm and <27.4 mm or area-derived diameter >18 and <28 mm
- Anatomy suitable for trans-femoral TAVI for both devices used in the study, including a minimum femoral diameter of 6 mm.
- Subject with a documented local Heart Team (HT) indication for TF TAVI
- Life expectancy longer than 1 year.
- Willingness to undergo clinical and echocardiographic follow-up after the procedure.
- Subject can understand the purpose of the clinical investigation, has signed voluntarily the informed consent form and is agreeing to the scheduled follow-up requirements
Exclusion Criteria:
- Male sex
- Non-calcific acquired aortic stenosis
- Native unicuspid/bicuspid aortic valve or congenital aortic abnormality
- Previous implantation of heart valve in any position
- Severe aortic regurgitation (> 3+)
- Severe mitral regurgitation (> 3+)
- Severe tricuspid regurgitation (> 3+)
- Severe left ventricular dysfunction (Left Ventricular Ejection Fraction (LVEF) < 30%)
- Echocardiographic evidence of intracardiac mass, thrombus or vegetation
- Untreated cardiac conduction disease in need of pacemaker implantation
- Evidence of acute Myocardial Infarction (MI) less than 30 days before signing informed consent
- Any need for emergency surgery
- Any active bleeding that precludes anticoagulation
- Liver failure (Child-C)
- End-stage renal disease requiring chronic dialysis or creatinine clearance < 30cc/min
- Pulmonary hypertension (systolic pressure > 80mmHg)
- A known hypersensitivity or contraindication to all anticoagulation/antiplatelet regimens (or inability to be anticoagulated for the index procedure), to cobalt chromium, to bovine and/or collagen, glutaraldehyde or contrast media
- Any medical, social or psychological condition that in the opinion of the investigator precludes the subject from giving appropriate consent or adherence to the required follow-up procedures
- Currently participating in another drug or device trial (excluding observational registries) for which the primary endpoint has not been assessed
- Subject under judicial protection, tutorship or curatorship (for France only)
