Studies on the prospect of bioprostheses by bovine aortic valve for human use

A total of 21 heart specimens from indigenous cattle (Bos indicus) were studied. The measurement and observation of bovine heart and aortic valve in different age group is the preliminary finding of this research work. After harvesting, the bovine aortic valves were measured and the sizes ranged from 21 mm to 35 mm in orifice diameter. In comparison with implanted aortic and mitral valves at NICVD in 1989, it indicates that the selected bovine heart valves (specially aortic valves) were similar to human valve size and can be used in future for implantation as far as the size is concerned. Now further study regarding making these tissue valves implantation worthy for clinical use is to be undertaken. We strongly feel the prospect is bright.
