Inclusion Criteria: 1. Age ≥ 18 years 2. Patients who are clinically indicated for aortic valve replacement 3. Patients who are willing and able to participate in the follow-up requirements, and provide written informed consent Exclusion Criteria: 1. Previous surgical or/and transcatheter cardiac valve replacement at any site 2. Previous open-heart surgical valve repair at any site 3. Any percutaneous cardiovascular intervention (excluding diagnostic percutaneous coronary artery intervention), cardiovascular surgery, carotid surgery within 30 days 4. Untreated mitral, tricuspid, or pulmonary valve diseases requiring procedural intervention 5. Untreated clinically significant coronary artery diseases requiring revascularization 6. Acute myocardial infarct within the previous 30 days 7. Severe right heart dysfunction 8. Active infection requiring antibiotic therapy including infective endocarditis 9. Hypertrophic obstructive cardiomyopathy (HOCM) 10. Severe symptomatic carotid artery stenosis 11. Stroke or TIA within 3 months or Modified Rankin Scale ≥ 4 disability 12. Chronic kidney disease (eGFR\<45 mL/min/1.73m2) or end-stage renal disease requiring chronic dialysis 13. Hematologic disorders: Leukopenia (WBC \< 3000 cell/mL), anemia (Hgb \< 9 g/dL), thrombocytopenia (Plt\< 50,000 cell/mL), or any known blood clotting disorder, deemed clinically significant after consultation with Hematooncology specialists 14.

Urgent, emergency or salvage surgeries 22. Known intolerance for periprocedural/post-procedural anticoagulation or antiplatelet therapy leading to be unable to undergo index procedure per physicians' judgement 23. Life expectancy ≤ 1 year due to non-cardiac reasons 24. Planned relevant concomitant procedure within 30 days post index procedure 25. Current or recent participation (within 6 weeks prior to index procedure) in another drug or device trial 26. Pregnant, breastfeeding or intend to become pregnant within 1 year 27. Currently incarcerated or unable to give voluntary informed consent
