Eligibility Criteria

Age65 Years - 100 Years
Sexall
Healthy VolunteersYes
Age GroupsOlder Adult (65+)

You may qualify if:

  • Age ≥65 years old, gender is not limited;
  • Patients assessed by a cardiac multidisciplinary team (MDT) expert panel as having severe aortic stenosis and suitable for transcatheter aortic valve replacement;
  • \*Severe aortic stenosis was defined as echocardiographically demonstrated transaortic valve flow velocity ≥4.0 m/s, or transaortic valve pressure differential ≥40 mmHg (1 mmHg=0.133 kPa), or aortic orifice area \<1.0 cm2, or effective aortic orifice area index \<0.6 cm2/m2; for low-pressure-differential-low-flow rate by dopa-phenobutylamine loading test, Doppler ultrasound evaluation or other imaging means of assessment for those judged to have severe aortic stenosis.
  • Have a core laboratory assessment that the patient is anatomically suitable for transcatheter aortic valve replacement;
  • Patients who understand the purpose of the trial, voluntarily participate in the trial, sign an informed consent form, and are willing to cooperate in the follow-up.

You may not qualify if:

  • Patients whose access or aortic root anatomical pattern is unsuitable for TAVR treatment;
  • Poor peripheral arterial conditions that preclude transfemoral TAVR;
  • Aortic annulus horizontal pinch angle ≥65° as measured by preoperative MDCT;
  • Patients at high risk of coronary obstruction requiring intraoperative coronary protection measures;
  • Patients requiring intraoperative delivery with a grapple assist system;
  • Previous implantation of a prosthetic aortic valve (bioprosthetic or mechanical);
  • Active stage of infective endocarditis or other active infection;
  • Combined mitral, tricuspid or severe macrovascular lesions requiring surgical or interventional intervention;
  • Echocardiography suggestive of left ventricular thrombus, intracardiac mass or redundant organisms;
  • Diagnosis of hypertrophic cardiomyopathy, restrictive cardiomyopathy, infiltrative cardiomyopathy (e.g. amyloidosis, haemochromatosis, nodular disease, etc.), constrictive pericarditis;
  • Severe obstruction of the left ventricular outflow tract without corrective measures;
  • Severe pulmonary hypertension (pulmonary artery systolic pressure \>70 mmHg measured by ultrasound);
  • Severe right heart dysfunction as suggested by a combined clinical and ultrasound assessment;
  • Severe left heart systolic insufficiency (left ventricular ejection fraction \<30%);
  • Cardiogenic shock or haemodynamic instability requiring ventricular assist device therapy within 30 days prior to enrolment;
  • +8 more criteria
