Background: Prosthetic heart valve for middle aged patients requiring valve replacement remains controversial Because of the co-morbidities and limited life expectancy, bioprosthesis is the likely choice for older aged patients.
Objective: The aim of the study was to quantify long term survival rate and major morbidity in patients undergoing heart valve replacement and to optimise selection criteria of biologic versus mechanical valve prostheses.
