| aortic sulcus | A broad deep groove on the medial aspect of the left lung above and behind the hilum receiving the arch of the aorta and the thoracic aorta. Synonym: sulcus aorticus. (05 Mar 2000) |
|---|---|
| aortic ultrasound | An ultrasound examination of the aorta to determine its size, shape and course. The diagnosis of abdominal aortic aneurysm can be made using this test. (27 Sep 1997) |
| aortic valve | The heart valve that divides the left ventricle and the aorta. The aortic valve opens during left ventricular contraction and then closes to prohibit the backwash of oxygenated blood from the aorta into the ventricle. The aortic valve has 3 valve cusps. (27 Sep 1997) |
| aortic valve insufficiency | Backflow of blood from the aorta into the left ventricle, owing to imperfect functioning of the aortic semilunar valve. (12 Dec 1998) |
| aortic valve prolapse | The downward displacement of the cuspal material (misalignment of the cusps) below a line joining points of attachment of the aortic valve leaflets. The prolapsed cusp may occlude the ventricular septal defect during ventricular diastole. (12 Dec 1998) |
| aortic valve stenosis | Narrowing of the orifice of the aortic valve or of the supravalular or subvalvular regions. (12 Dec 1998) |
| aortic vestibule | The anterosuperior portion of the left ventricle of the heart immediately below the aortic orifice, having fibrous walls and affording room for the segments of the closed aortic valve. Synonym: Sibson's aortic vestibule, vestibulum aortae. (05 Mar 2000) |
| aortic-pulmonic window | The indentation of the left side of the mediastinum by the lung partially interposed between the aortic arch and the left pulmonary artery, seen on frontal radiographs of the chest. Synonym: aortic-pulmonic window. (05 Mar 2000) |
| aortico-left ventricular tunnel | Congenital connection between the aorta above exit of coronary arteries and the left ventricle. (05 Mar 2000) |
| aorticopulmonary window | A small congenital opening between the aorta and pulmonary artery about 1 cm above the semilunar valves, e.g., aorticopulmonary window. Synonym: aorticopulmonary window. (05 Mar 2000) |
| aorticorenal | Related to the aorta and kidney, specifically the ganglion aorticorenale. (05 Mar 2000) |
| aorticorenal ganglia | A semidetached portion of the coeliac ganglia, at the origin of each renal artery; contains the sympathetic neurons innervating the vasculature of the kidney. Synonym: ganglia aorticorenalia. (05 Mar 2000) |
| aortic stenosis |
Narrowing of the aortic valve opening, causing obstruction of blood flow into the circulation. The condition causes the heart to work harder and the muscle in the wall of the left ventricle (lower chamber) to thicken.

| aortic insufficiency |
Failure of the aortic valve to prevent backflow of oxygen-rich blood from aorta to left ventricle, resulting in dilatation, hypertrophy and ultimately failure of the pumping mechanism.

|
| aortic valve |
Valve located where the aorta meets the left ventricle of the heart. It allows the blood to flow from the heart into the aorta and prevents back flow.

| aortic aneurysm |
Localised ballooning of the aorta, potentially causing pressure on adjacent structures and liability to rupture.
