[Viability of new valvular homografts. An evaluation at the Henri Mondor Hospital].
The renewed interest in valvular homograft is due to the new concept of their viability. This viability requires procurement from organ donors and preparation in rich tissue culture medium immediately prior to cryopreservation. This viability, confirmed by morphological tests especially electron microscopy, and by cell culture tests is the basis for satisfactory long-term results. Antigenic aspects justify rigorous respect of A-B-O compatibility. A preliminary clinical series of 35 valvular homografts (16 on the right side and 19 in the aortic position), implanted especially in children over the last five years at the Henri Mondor Hospital, is reported here, No tissue failures have been reported to date.
