Comparison of porcine versus bovine pericardial bioprosthesis in the mitral position

摘要

Background There are no reports of midterm outcomes after mitral valve replacement with a 25-mm bioprosthesis in a large series of patients. This study aimed to examine perioperative and midterm outcomes of bioprosthetic valve choice, porcine or bovine pericardial, in the mitral position, focusing on 25-mm valves.
