THE COURSE OF THE INTERVENTRICULAR CORONARY ARTERIES AND MYOCARDIAL BRIDGES IN ONE-HUMPED CAMEL

ABSTRACT The aim of the study was to describe the morphology of the myocardial bridges (MCB) in one-humped camels. Hearts of 17 male wrestler one-humped camels were grouped into three according to the relationship between the course of the interventricular branches of the coronary arteries and MCB formations. MCBs were found in six hearts (35.29%) and were on the right and left side in one (5.88%) and five hearts (29.41%), respectively. The MCB widths were measured by micrometric calibre and the values were found was between 7-15 mm. These results show that both the course of the interventricular branches of the coronary arteries and the localization and existence of MCBs were varying from one specimen to another in the camel. Key Words: myocardial bridges, coronary artery, camel   DEVEDE KORONER ARTERLERİN İNTERVENTRİCULER DALLARININ SEYRİ VE KALP KAS KÖPRÜLERİ ÖZET Develerde kalp kas köprülerinin morfolojik özelliklerini tanımlamak amacıyla yapılan bu çalışma 17 adet erkek tek hörgüçlü güreş devesi kalbi kullanıldı. Kalpler, koroner arterlerin interventrikuler dallarının seyri ve kalp kas köprülerinin şekillenişi arasındaki ilişkiye göre üç grup altında incelendi. Kalplerden birinin sağ yüzünde (%5,88) ve beşinin sol yüzünde (%29,41) olmak üzere, toplam altı kalpte (%35,29) kalp kas köprüsü oluşumu tespit edildi. Mikrometrik kumpas ile ölçülen kalp kas köprüsü genişliklerinin 7-15 mm arasında olduğu belirlendi. Elde edilen bulgular, devede hem koroner arterlerin subperikardial ve intramiyokardiyal seyirleri bakımından hem de kalp kas köprülerinin varlığı ve yerleşim yerleri bakımından bireysel farklılıklar bulunduğunu gösterdi. Anahtar Kelimeler: kalp kas köprüleri, koroner arter, deve
