In patients undergoing aortic-valve or mitral-valve replacement, either a mechanical or biologic prosthesis is used. Biologic prostheses have been increasingly favored despite limited evidence ...

Choosing the optimal aortic valve prosthesis for middle-aged patients (late 40s to early 60s) with aortic stenosis presents a challenge. The available options all have substantial drawbacks that ...

have performed the first implantation of the Medtronic CoreValve® Transcatheter Aortic Valve Prosthesis in the United States. The CoreValve System is a new device that treats severe aortic ...

8 The purpose of the present study was to assess the safety and effectiveness of TAVR with a self-expanding prosthesis as compared with surgical valve replacement in patients with severe aortic ...

We should also emphasize that implantation of a small prosthesis does not necessarily result in PPM, and can be perfectly adequate in a patient with small body size. In conclusion, PPM is a ...

TAVI uses the expandable Medtronic CoreValve prosthesis, which is delivered through the femoral or subclavian arteries and allowed to expand into the location of the defective aortic valve.

An aortic valve replacement can be a lifesaving measure to preserve healthy heart function and robust circulation throughout the body. Like any heart procedure, the recovery can be lengthy and ...

Aortic valve replacement is a surgery that removes and replaces the damaged aortic valve with a prosthetic valve. It is a major surgery. Not everyone is a good candidate for this surgery.

“While surgery removes the native valve for implanting a new biological prosthesis (ie, the term replacement is correct), transcatheter treatment involves crushing the aortic valve leaflets (not ...

During aortic valve replacement surgery, the size of the orifice of the prosthetic valve can sometimes be smaller than necessary for adequately supplying blood to the body and can result in the ...

It is also known as percutaneous aortic valve replacement (PAVR). Prosthetic heart valves are also utilized to replace native heart valves which function poorly or need a replacement with an ...

A late-breaking study presented today at the 2025 Society of Thoracic Surgeons (STS) Annual Meeting reveals that mechanical aortic valve ... analysis to date of prosthetic valve outcomes ...
