A comparison of outcomes between bovine pericardial and porcine valves in 38 040 patients in England and Wales over 10 years

OBJECTIVES Biological valves are the most commonly implanted prostheses for aortic valve replacement (AVR) surgery in the UK. The aim of this study was to compare performance of porcine and bovinepericardial valves implanted in AVR surgery with respect to survival and reintervention-free survival in a retrospective observational study.
CONCLUSIONS There were no differences in reintervention-free survival between bovine pericardial and porcine valves used in first-time AVR ± CABG up to a maximum of 10 years.
