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 ...

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 ...

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.

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 ...

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.

LOS ANGELES — Aortic mechanical valves are associated with better survival ... 86% received a bioprosthetic device and 14% received a mechanical prosthesis. After a median follow-up of more ...

LOS ANGELES -- Survival outcomes favored mechanical valves for isolated surgical aortic valve replacement (SAVR) for people ...

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 study presented at the 2025 Society of Thoracic Surgeons (STS) Annual Meeting reveals that mechanical 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 ...
