Post-Operative Echocardiographic follow up After Mitral Valve Replacement By Different Types Of Biological Valves

Abstract

-Objectives: This retrospective study compares porcine with bovine bioprosthesis in mitral position with regard to valvular degeneration -Methods:between 2005 and 2019 , 15 patients underwent mitral valve replacement with porcine Epic biological valve (St-Jude) and 15 patients underwent mitral valve replacement by bovine Carpentier –Edwards Perimount biological valve and follow up ecocardiogarphy was done to evaluate valvular degeneration of both types -Results: Bovine type showed longer durability than porcine and less valvular degeneration within 14 years of follow up regardless age of patient , cause of valve replacement ,lesion of valve -Conclusion: bovine bioprothesis are better than porcine regarding durability
