入选标准
- •Failing aortic bioprosthetic valve demonstrating ≥ moderate stenosis and/or ≥ moderate insufficiency
- •Bioprosthetic valve size suitable for SAPIEN X4 THV
- •NYHA functional class ≥ II
- •Heart Team agrees the subject is at high or greater surgical risk
- •The subject has been informed of the nature of the study, agrees to its provisions and has provided written informed consent.
排除标准
- •Anatomical characteristics that would preclude safe femoral placement of the introducer sheath or safe passage of the delivery system
- •Failing valve has moderate or severe paravalvular regurgitation
- •Failing valve is unstable, rocking, or not structurally intact
- •Known severe patient-prosthesis mismatch or bioprosthetic valve with residual mean gradient > 20 mmHg at the end of the index procedure for implantation of the original valve
- •Increased risk of THV embolization
- •Surgical or transcatheter valve in the mitral position
- •Severe mitral regurgitation (> 3+) or ≥ moderate mitral stenosis
- •Need for mitral, tricuspid or pulmonic valve intervention within the next 12 months
- •Left ventricular ejection fraction < 20%
- •Cardiac imaging evidence of intracardiac mass, thrombus or vegetation
- •Increased risk of coronary artery obstruction after THV implantation
- •Myocardial infarction within 30 days prior to the study procedure
- •Hypertrophic cardiomyopathy with subvalvular obstruction
- •Subjects with planned concomitant ablation for atrial fibrillation
- •Clinically significant coronary artery disease requiring revascularization
- •Any surgical or transcatheter procedure within 30 days prior to the study procedure. Implantation of a permanent pacemaker or implantable cardioverter defibrillator is not considered an exclusion.
- •Any planned surgical or transcatheter intervention to be performed within 30 days following the study procedure
- •Endocarditis within 180 days prior to the study procedure
- •Stroke, transient ischemic attack or neurological signs and symptoms attributed to carotid or vertebrobasilar disease within 90 days prior to the study procedure
- •Hemodynamic or respiratory instability requiring inotropic or mechanical support within 30 days prior to the study procedure
- •Renal insufficiency and/or renal replacement therapy
- •Leukopenia, anemia, thrombocytopenia
- •Inability to tolerate or condition precluding treatment with antithrombotic therapy
- •Hypercoagulable state or other condition that increases risk of thrombosis
- •Absolute contraindications or allergy to iodinated contrast that cannot be adequately treated with premedication
- •Subject refuses blood products
- •Body mass index > 50 kg/m2
- •Estimated life expectancy < 24 months
- •Female who is pregnant or lactating
- •Active SARS-CoV-2 infection or previously diagnosed with COVID-19 with sequelae that could confound endpoint assessments
- •Participating in another investigational drug or device study that has not reached its primary endpoint
- •Subject considered to be part of a vulnerable population
