简要总结

TAVR is a crucial treatment method for aortic valve diseases. The requirements for the device to cross the aortic arch and for the bioprosthetic valve to be coaxial are quite high, and they are key steps for the success of the surgery. Investigators' aim is to evaluate the safety and effectiveness of a variable-bend sheath for the TAVR procedure.
