Morphomatrical Analysis of Aortic Valves of Bovine Heart for Bioprosthetic Purpose

M.N. Islam, M.Z.I Khan, S.R. Khan and M.A. Haque

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, the size 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
