Eligibility Criteria

Inclusion Criteria

•Patients with symptomatic aortic valve regurgitation diseases, and New York Heart Association (NYHA) ≥ II;
•Subject must have Society of Thoracic Surgeons (STS) score ≥8% or have been evaluated as inoperable by the surgical team \[defined as rate of death #50% within 30 d post-surgery or accompanied with irreversible occasions of other factors prevent surgeries (such as heavily calcified (porcelain) ascending aorta, weakness, chest malformation, liver dysfunction, pulmonary dysfunction and so on ); (Note: age of inoperable patients can be expanded to ≥ 50);
•Aortic valve anatomy is suitable for TAVR evaluated by the investigators;
•Patients who can sign informed consent form, and are willing to accept relevant examinations and clinical follow-ups.

Exclusion Criteria

•Active endocarditis;
•Acute myocardial infarction or coronary revascularization occurred within 1 month before procedure;
•Cerebrovascular accident (CVA) occurred within 30 days before procedure;
•The echocardiogram indicates the presence of mass, thrombus or vegetation in left ventricle and left atrium;
•Hypertrophic obstructive cardiomyopathy;
•Other valve diseases that need interventions;
•Previous aortic valve implantation (mechanical or biological);
•Allergic to Nickel-titanium alloys or contrast agents or cattle-originated products;
•Known allergy or contraindication to all anticoagulation, or anticoagulation can not be used during the TAVR;
•In presence one of the following (from selection to the day of procedure index): a other diseases that may shorten life expectancy to less than 12 months (recurrent or metastatic cancer, congestive heart failure); b drug abuse (such as cocaine, heroin and so on); c planned additional operations that may result in incompliance or data confusion;
