A new porcine bioprosthesis: in vitro and in vivo evaluation.
The Wessex porcine bioprosthesis exhibits satisfactory hydrodynamic performance and durability comparable to other clinical porcine valves. In vivo performance and pathological studies of explanted valves confirm adequate biodurability and haemodynamic performance. Early clinical results are satisfactory and encourage further study.
