Beschrijving
Inclusion Criteria:
- Male or non-pregnant female, ≥18 years
- Patients with symptomatic severe aortic stenosis who are scheduled to undergo TAVR with commercialized transcatheter aortic valve system.
- Compatible left common carotid artery (6.5-10 mm) and brachiocephalic artery (9-15mm) diameters without significant stenosis (> 70%)
- Patients who are able to understand the study objectives, voluntarily participate, sign the informed consent form, and are willing to undergo required examinations and clinical follow-up.
Exclusion Criteria:
General
- Contraindications to MRI, or planned implantation of an MRI-incompatible device at the index procedure, or planned implantation of an MRI-incompatible pacemaker or defibrillator within 30 days post-procedure.
- Acute myocardial infarction ≤ 30 days before the intended treatment
- Pure aortic regurgitation
- Pre-existing prosthetic aortic valve
- Echocardiographic evidence of intracardiac or aortic mass, thrombus, or vegetation
- Contraindication to antiplatelet and/or anticoagulant therapy, nitinol , or contrast media, or refusal to receive blood transfusions
- Vulnerable populations, including those unable to adequately understand the trial, those potentially subject to undue influence or coercion, those unable to complete the informed consent process, and those with severe disabling dementia or cognitive impairment Anatomic
- Vasculature (ie, right radial/brachial artery, carotid artery) precluding the device access
- Patients whose brachiocephalic or left carotid artery reveals significant stenosis(>70%), ectasia, dissection, or aneurysm at the ostium or within 3 cm of the ostium

Tijdsspanne: 30 days post-procedure
|
MACCE: all-cause death, disabling and non-disabling stroke, and Acute Kidney Injury (AKI) Stage 3 or higher at discharge or within7 days post-procedure, whichever occurs first (definitions of all-cause death, stroke, and AKI are based on VARC-3 criteria)
|
30 days post-procedure
