Abstract:
Morphomatrical analysis of aortic valves of bovine heart was done
for the purpose of manufacturing of bioprosthetic materials in Bangladesh. The
study analyzed 32 healthy fixed bovine hearts; 50% of them obtained from males,
50% of them from female animals ranged from 2 to 4 years old. The characteristics
assessed related to age and sexes were the following: number and height of the
cusps and size of the lunulae. This study included the assessment of 32 aortic
valves of the hearts, 8 valves from each of 2, 2.5, 3 and 4 years of indigenous
cattle. All the bovine hearts assessed in the present study possessed tricuspid
aortic valve. The values of the heights of left, right and noncoronary cusps
were 14.91±2.47, 14.25±2.60 and 15.19±1.75 mm, respectively and NC cusp had
the largest dimensions, followed by the RC and the LC cusps, whose dimensions
were nearly similar. The highest values of lunula (width and length) were 8.31±1.35
mm for LC in case of width and 32.22±3.10 mm for RC in case of length. Data
about height of the cusps, thesize of the lunula (width and length)
of the cusps and their anatomical relations facilitate the manufacturing of
bovine tissue valves as well as those can be used in valve replacements as like
as stentless porcine and bovine pericardial bioprostheses are being used clinically
