Eligibility
Inclusion criteria
Inclusion criteria: 1) age =75 years, STS-PROM/ EuroSCORE IIf > 8%; 2) patients with severe aortic stenosis (mean transaortic gradient =40 mmHg [1 mmHg=0.133 kPa], or transaortic flow velocity =4.0 m/s, or aortic valve orifice area 10 mmHg, or pulmonary artery systolic pressure > 50 mmHg); 4) NYHA grade =II; 5) patients who are anatomically suitable for transfemoral transcatheter aortic valve replacement and percutaneous balloon mitral valve separation; 6) patients who can understand the purpose of the experiment, sign the informed consent form, and are willing to accept the relevant clinical follow-up.
Exclusion criteria
Exclusion criteria: 1) Aortic root and mitral valve region anatomy and lesions are not suitable for prosthetic valve implantation or balloon dissection; 2) The presence of intracardiac mass, thrombus or vegetation by echocardiography; 3) Allergic to Nitinol, PET polyethylene terephthalate and other valve materials or contrast agents; They could not tolerate anticoagulant and antiplatelet therapy. 4) congenital aortic valve malformation (except bicuspid valve); 5) vascular diseases affecting device access; 6) only consents to undergo transcatheter aortic-valve replacement or percutaneous balloon mitral valve isolation.
