Abstract
Bu çalışma, Hasak koyununun kalbindeki koroner sirkülasyonu ve koroner arterler üzerinde bulunan kalp kası köprüsünün makroskobik özelliklerini belirlemek amacı ile yapıldı. Araştırmada 10 adet Hasak koyun kalbi kullanıldı. Latex enjeksiyon ve korozyon kast tekniklerinden faydalanıldı. Kalbin arteriyel vaskularizasyonunun, a. coronaria dextra ve a. coronaria sinistra tarafından sağlandığı gözlendi. A. coronaria dextra ve dallarının a. coronaria sinistra’ya göre daha zayıf ve az sayıda septal dal verdiği belirlendi. A. coronaria dextra’nın, r. interventricularis subsinuosus ve r. interventricularis paraconalis ile anastomoz yaptığı belirlendi. Arteria coronaria sinistra, arteria coronaria dextra, ramus interventricularis paraconalis, ramus interventricularis subsinuosus, ramus circumflexus sinister ve ramus circumflexus dexter’in subepicardial yağ dokusu altında seyrettiği tespit edildi. Bu damarlardan ayrılan ventriküler dalların ise başlangıçlarında subendokardiyal, devamında ise intramiyokardiyal olarak seyrettiği görüldü. Kalp kas köprüsünün ramus interventricularis paraconalis ve ramus circumflexus sinister’de daha fazla olduğu bulundu
Abstract
This study was conducted to determine of the coronary circulation and macroscopic properties of myocardial bridge on coronary arteries in Hasak sheep heart. In this study, 10 Hasak sheep hearts were used as the material. Latex injection and corrosion cast techniques were utilized. Dissected hearts were evaluated and photographed. Arterial vascularisation of the heart was provided by the left and right coronary arteries. The septal branches from which the right coronary artery and its branches gave off during their course were lesser in number and thinner than the septal branches from which the left coronary artery and its branches gave off during their course. Right coronary artery anastomoses were found between r. interventricularis subsinuosus and r. interventricularis paraconalis. Left coronary artery, right coronary artery, interventricular paraconal branch, interventricular subsinuosal branch, left circumflexus branch, and right circumflexus branch were located under the subepicardial fat tissue. It was seen that ventricular branches of these vessels, on the other hand, had a subendocardial course initially, and continued as intramyocardially. These vessels run intramyocardially in variable lenghts and then return to the subepicardial surface. It was found that the myocardial bridge was more common in ramus interventricularis paraconalis and ramus circumflexus sinister
