| 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) |
| aortitis | <medicine> Inflammation of the aorta. Origin: Aorta + -itis. Source: Websters Dictionary (01 Mar 1998) |
| aortoannular ectasia | annuloaortic ectasia |
| aortocoronary | Relating to the aorta and the coronary arteries. (05 Mar 2000) |
| aortocoronary bypass | Vein grafts or other conduits shunting blood from the aorta to branches of the coronary arteries, to increase the flow beyond the local obstruction. Synonym: aortocoronary bypass. (05 Mar 2000) |

| aortic sinusal aneurysm |
aneurysm arising in the aortic sinuses of Valsalva; it is a rare, usually congenital lesion that begins as finger-like projections in the right or noncoronary sinuses and can progress to rupture, usually into the right ventricle or atrium, causing volume overload and congestive heart failure.
