| aortic dwarfism | Underdevelopment of physical stature associated with severe aortic stenosis. (05 Mar 2000) |
|---|---|
| aortic facies | The pale sallow complexion of one suffering from incompetence of the aortic valve. (05 Mar 2000) |
| aortic foramen | The opening in the diaphragm bounded by the two crura, the vertebral column, and the median arcuate ligament, through which pass the aorta and thoracic duct. Synonym: hiatus aorticus, aortic foramen, aortic opening. (05 Mar 2000) |
| aortic hiatus | The opening in the diaphragm bounded by the two crura, the vertebral column, and the median arcuate ligament, through which pass the aorta and thoracic duct. Synonym: hiatus aorticus, aortic foramen, aortic opening. (05 Mar 2000) |
| aortic incompetence | Defective closure of the aortic valve permitting regurgitation into the left ventricle during diastole. (05 Mar 2000) |
| aortic insufficiency | A congenital or acquired heart valve abnormality that results in the abnormal back flow of blood in the aorta, through an incompetent aortic valve and into the left ventricle. Chronic aortic insufficiency leads to enlargement of the left ventricle and pulmonary congestion. If left uncorrected, congestive heart failure will result. Aortic valve replacement is eventually necessary in most cases of significant valvular incompetence. (27 Sep 1997) |
| aortic knob | The prominent shadow of the aortic arch on a frontal chest radiograph. (05 Mar 2000) |
| aortic knuckle | The contour of the aortic arch protruding from the mediastinal silhouette in an anteroposterior (AP) radiograph of the chest. (05 Mar 2000) |
| aortic laceration | <radiology> Deceleration injury, 80% at aortic isthmus (just distal to insertion of lig. Arteriosum), other sites: proximal ascending aorta, descending aorta at diaphragmatic hiatus, transverse aortic arch, laceration usually transverse, all layers involved in only 40% (12 Dec 1998) |
| aortic lymphatic plexus | A plexus of lymph nodes and connecting vessels lying along the lower portion of the abdominal aorta. Synonym: plexus aorticus. (05 Mar 2000) |
| aortic murmur | A murmur produced at the aortic orifice, either obstructive or regurgitant. (05 Mar 2000) |
| aortic nerve | <anatomy, nerve> A branch of the vagus which ends in the aortic arch and base of the heart; composed entirely of afferent fibres; its stimulation elicits a brainstem reflex which causes slowing of the heart, dilation of the peripheral vessels, and a fall in blood pressure. Synonym: Cyon's nerve, depressor nerve of Ludwig, Ludwig's nerve. (05 Mar 2000) |
| aortic notch | The notch in a sphygmographic tracing caused by rebound following closure of the aortic valves. (05 Mar 2000) |
| aortic occlusion | A blockage of the aorta somewhere along its path. This can result in irreversible damage to the organs which depend on aortic blood below the level of the blockage. See: atherosclerosis. (27 Sep 1997) |
| aortic opening | The opening in the diaphragm bounded by the two crura, the vertebral column, and the median arcuate ligament, through which pass the aorta and thoracic duct. Synonym: hiatus aorticus, aortic foramen, aortic opening. (05 Mar 2000) |

| aortic atresia |
absence or closure of the aortic root orifice, a rare congenital anomaly in which the left ventricle is hypoplastic, oxygenated blood passing from the left into the right atrium through a septal defect, and the mixed venous and arterial blood passing from the pulmonary artery to the aorta by way of a patent ductus.
