Atrioventricular heart valves of indigenous cattle (bos indicus): the morphology and morphometry

Abstract

Aim: 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. Materials and Methods: 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. Results: A strongly significant (p Conclusion: 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.
