Morphological importance of coronary ostia in sheep and swine
Anatomia, Histologia, Embryologia, 2022AbstractThe aortic valve was investigated in 58 sheep and 60 swine without heart disease. After fixation in 4% formalin, the distance between the ostia and the elements of the right/left aortic sinuses was measured. For the left coronary ostium (LCO), it was found that in sheep 81% were below and 19% at the level of intercomissural line (IL).

The positions of coronary arterial ostia
Clinical Anatomy, 1996The positions of the coronary arterial ostia were examined in the cadavers of 38 adults. All the ostia were related to the aorta and none to the pulmonary artery. The aortic valves in 37 specimens were normal and possessed three cusps, while one was bicuspid.

Direct cannulation of the coronary ostia
Multimedia Manual of Cardio-Thoracic Surgery, 2005Direct cannulation of the coronary ostia is a technique used by many surgeons in aortic valve surgery, especially when the valve is incompetent. It is safe and feasible, but the small risk of it causing a potentially devastating ostial stenosis must be kept in mind.

Congenital absence of coronary ostia in a single/common coronary system
Cardiology in the Young, 2019AbstractCoronary ostial atresia seen with pulmonary atresia and coronary-cameral fistulae or, more rarely, in isolation manifested as left main coronary artery atresia, is well described. We describe the clinical course and post-mortem findings in a neonate who suffered a fatal cardiac arrest and was found to have congenital absence of both coronary ...

Sinus of valsalva aneurysms involving both coronary ostia
Catheterization and Cardiovascular Diagnosis, 1993AbstractSinus of Valsalva aneurysms are a rare cause of angina or myocardial infarction. We describe a patient with unstable angina and massive unruptured aneurysms of both coronary sinuses causing severe distortion of both coronary ostia, to our knowledge not previously reported.

Imaging of Coronary Grafts Without Catheterization of Coronary Ostia
1984Selective angiography of the coronary arteries is the standard method of visualizing radiologically not only the heart vessels, but also bypass grafts. The invasive nature of this procedure, however, limits its application [1, 2].

Morphometry of the coronary ostia in the domestic shorthair cat [PDF]
Anatomia Histologia Embryologia, 2014 Introduction: Diagnosis and treatment of heart diseases due to changes in the coronary vascularisation need a detailed knowledge on the morphology and possible variations of the aortic valves and coronary ostia. This study was performed to clarify details on morphology and morphometry of these structures in domestic shorthair cats.
