Mechanical Versus Bioprosthetic Aortic Valve Replacement in Middle-Aged Adults: Western Australian Experience

Selection of the type of prosthesis for middle-aged patients undergoing aortic valve replacement (AVR) is complex, where several patient and prosthesis factors must be considered. A large cohort of Western Australian (WA) patients undergoing AVR was studied and long-term survival between patients receiving bioprosthetic valves (BV) and mechanical valves (MV) was compared.
