| Summary: | <b>Aim:</b> The aim of the study was to detect the gross morphology
and measurement of the length of chordae tendineae
of bovine atrioventricular heart valves for future bioprosthesis.<p>
<b>Materials and Methods:</b> Forty atrioventricular heart
valves were obtained from cattle. The tricuspid and bicuspid
valves were harvested by opening the four chambers
of the collected heart specimen by placing finger tightly
into the cusps of the valves and then the ventricular myocardium
muscle trimmed out by scissor slowly. Harvested
valves were gently packed with cotton wool to maintain the
normal architecture of the leaflets and then preserved in
10% formalin solution.<p>
<b>Results:</b> A strongly significant (p<0.01) difference was
found amongst the age group of anterior, intermediate and
posterior cusps of the tricuspid valves. It's also same for
the posterior cusp of the bicuspid valve (p<0.01), although
a statistically significant (p<0.05) difference was found
for anterior cusps of the bicuspid valves. The mean length
of the chordae tendineae of anterior cusp of 2.5 years age
group was higher than posterior cusp.<p>
<b>Conclusion:</b> The arrangement of the valvular apparatus,
the close relation tricuspid and bicuspid valves and adjacent
structures like papillary muscles, chordae tendineae
and atrioventricular conduction bundle are all important
in the clinical arena for future bioprosthesis and other vital
purposes. |
