Atrioventricular heart valves of indigenous cattle (Bos indicus): The morphology and morphometry

Amaç: Bu çalışmanın amacı, sığır atrioventricular kalp kapakçıklarında yer alan chordae tendinea’ların uzunluk ölçümleri ve morfolojisinin ilerde yapılacak biyoprotezler için incelenmesidir. Gereç ve Yöntem: Çalışmada sığırlardan alınan kırk atrioventricular kalp kapakçığı kullanıldı. Valva tricuspidalis ve valva bicuspidalis, temin edilen kalplerin el ve makas yardımı ile dikkatlice açılması ve ventriküler miyokardiyum’un uzaklaştırılması ile toplandı. Toplanan kapakçıklar pamuğa sarılarak kapakçıkların normal yapısı korunmaya çalışıldı ve daha sonra %10 formol solusyonu içerisinde muhafaza edildi. Sonuç: Valva tricuspidalis’e ait cuspis angularis, cuspis septalis ve cuspis parietalis’in uzunlukları arasında yaşa bağlı önemli istatistikî fark (p

Yerli sığır (Bos indicus) ırkının atrioventricular kalp kapakçıkları: Morfoloji ve morfometri

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
