Eligibility Criteria

Age65 Years+
Sexall
Healthy VolunteersNo
Age GroupsOlder Adult (65+)

You may qualify if:

  • Age ≥ 65;
  • 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.

You may not qualify if:

  • 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;
  • Stenosis of common carotid artery, internal carotid artery or vertebral artery #70%;
  • Severe left ventricular dysfunction, left ventricular ejection fraction (LVEF) \<20%;
  • Hepatic encephalopathy or acute active hepatitis;
  • Receiving hemodialysis;
  • Bleeding tendency or history of coagulopathy or refuse to receive transfusion;
  • +6 more criteria
