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

Year 2012, Volume: 28 Issue: 1, 1 - 4, 01.03.2012

Abstract

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<0.01) tespit edildi. Bu durum valva bicuspidalis’in cuspis parietalis’i (p<0.01) ve cuspis septalis’i (p<0.05) içinde doğrulandı. Cuspis septalis’e ait chordae tendinea’ların ortalama uzunluğunun 2.5 yaşlı grupta cuspis parietalis’e ait olanlardan daha uzun olduğu tespit edildi. Öneri: Kalp kapakçıklarını oluşturan yapıların yerleşimi, valve tricuspidalis ve bicuspidalis aynı zamanda musculus papillaris, chordae tendineae ve antrioventricular iletim yolları klinik açıdan ve gelecekte yapılacak biyoprotezler için önem arz etmektedir.

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

Year 2012, Volume: 28 Issue: 1, 1 - 4, 01.03.2012

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<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.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.
