Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Despite 2020 American College of Cardiology (ACC)/American Heart Association (AHA) guidelines recommended SAVR for patients with symptomatic severe AS aged \<65 years, the previous data from United States nationwide Vizient Clinical Data Base and Northern New England Cardiovascular Disease Group Consortium (NNECDSG) registry demonstrated dramatic growth in TAVR utilization in younger patients aged \<65 years from 2015 to 2021/2022, which is possibly driven by increased TAVR utilization in low surgical risk patients.
However, TAVR has never been systematically tested in young (\<65 years old), low-risk patients, with many unanswered questions, especially the safety and effectiveness of TAVR in patients with bicuspid aortic valves and the durability of transcatheter heart valves. Furthermore, we noticed that the patients between 65 years old and 70 years old accounted for 23.3% of all the TAVR patients and this patient subgroup were underrepresented in the previous study, which makes it necessary to also explore the interested endpoints in this subgroup.
The aim of this study is to establish the safety and efficacy of Sapien 3 TAVR in young (50\~70 years old) Chinese patients with severe symptomatic AS, including Type-1 bicuspid population and to explore the durability performance of Sapien 3 in this cohort.

300 retrospectively enrolled patients
Procedure: TAVR
Transcatheter Aortic Valve Replacement (TAVR)
TAVR procedure was performed according to standard clinical practice. Successful vascular access, delivery and deployment of the device and successful retrieval of the delivery system will be attempted. Vascular access site will be through transfemoral on the basis of pre-procedural evaluation of access site vessel. The procedure will be performed under local or general anesthesia and per clinical practice standard.
150 prospectively enrolled patients
Procedure: TAVR
Transcatheter Aortic Valve Replacement (TAVR)
TAVR procedure was performed according to standard clinical practice. Successful vascular access, delivery and deployment of the device and successful retrieval of the delivery system will be attempted. Vascular access site will be through transfemoral on the basis of pre-procedural evaluation of access site vessel. The procedure will be performed under local or general anesthesia and per clinical practice standard.

Exclusion Criteria
* Aortic valve is a congenital unicuspid valve, congenital Type-0 or Type-2 bicuspid valve, or quadricuspid valve.
* Severe femoral, iliac or aortic atherosclerosis, calcification, coarctation, aneurysm or tortuosity, which prevents transfemoral TAVR.
* Evidence of an acute myocardial infarction ≤ 1 month (30 days), with evidence of myocardial necrosis in a clinical setting consistent with acute myocardial ischemia.
* Need for open heart surgery (including severe aortic regurgitation, mitral regurgitation or stenosis, or tricuspid regurgitation, congenital heart disease, AF, complex coronary artery disease).
* Aortic disease: a. bicuspid aortic valve with an ascending aorta diameter ≥ 45mm b. tricuspid aortic valve with an ascending aorta diameter ≥ 50mm.
* Pre-existing mechanical or bioprosthetic valve in any position.
* Hemodynamic or respiratory instability requiring inotropic support, mechanical ventilation or mechanical heart assistance within 30 days of the screening visit.
* Emergency interventional/surgical procedures within 30 days of the valve implant procedure.
* Hypertrophic cardiomyopathy with or without obstruction.
* Ventricular dysfunction with LVEF \< 30%.
* Cardiac imaging (echo, CT, and/or MRI) evidence of ventricular mass, thrombus or vegetation.
* Inability (including allergy) to heparin, iodine contrast agent, warfarin or NOAC, aspirin or clopidogrel.
* Stroke or transient ischemic attack (TIA) within 180 days of the valve implant procedure.
* Renal replacement therapy at the time of screening.
* Severe lung disease (FEV1 \< 50% predicted) or currently on home oxygen.
* Estimated life expectancy \< 24 months.
* Currently participating in an investigational drug or another device study. Note: Trials requiring extended follow-up for products that were investigational, but have since become commercially available, are not considered investigational trials. Observational studies are not considered exclusionary.
