aortic valve replacement

Full Definition

Aortic valve replacement (AVR) is a cardiac surgical procedure performed to replace a diseased or malfunctioning aortic valve with either a mechanical or biological prosthetic valve. The procedure is indicated for severe aortic stenosis or regurgitation that cannot be managed conservatively. Access is typically gained through a median sternotomy, though minimally invasive approaches are increasingly used. The choice between mechanical and biological valves depends on patient age, lifestyle, and anticoagulation considerations.
