| 설명 | 관 혹은 통로에 있는 막과 같은 주름. 내용물의 역류를 막는다. 1.심장판막: 우심방과 우심실사이의 삼첨판, 좌심방과 좌심실사이의 승모판, 우심실과 폐동맥사이의 폐동맥반월판, 좌심실과 대동맥사이의 대동맥반월판이 있다. 2.정맥판막: 정맥에서 발견되는 내막의 작은 첨 혹은 주름. 탄력성이 적어 역류되기 쉬운 정맥혈의 흐름을 역류없이 정상적인 방향으로 지속되도록 해준다. 3.인공판막: 심장판막부족이나 심장판막협착이 있어 더이상 자신의 판막으로는 생존이 불가능할 때 대신 이식하게 되는 인공판막을 말한다. 크게 동물의 조직을 이용한 것과 그렇지 않은 것으로 양분할 수 있다. 동물의 조직을 이용한 것은 주로 돼지나 소의 판막 또는 심외막 등을 이용하며, 그렇지 않은 것은 특수한 금속을 이용하여 만든다. |

| mediastinal branches of thoracic aorta | Numerous small arteries supplying the pleura and lymph nodes of the posterior mediastinum. Synonym: rami mediastinales aortae thoracicae, posterior mediastinal arteries. (05 Mar 2000) |

| medionecrosis of the aorta | Loss of elastic and muscle fibres in the aortic media, with accumulation of mucopolysaccharide, sometimes in cystlike spaces between the fibres; a disease of unknown cause, which may be inherited and which predisposes to dissecting aneurysms. Synonym: Erdheim disease, medionecrosis aortae idiopathica cystica, medionecrosis of the aorta, mucoid medial degeneration. (05 Mar 2000) |
| pericardial branch of thoracic aorta | Small branches of thoracic aorta distributed to the pericardium, in the region of the oblique pericardial sinus, and to posterior mediastinal lymph nodes. Synonym: rami pericardiaci aortae thoracicae. (05 Mar 2000) |
| groove for arch of aorta | A broad, deep sulcus arching superiorly over the hilus on the mediastinal surface of the left lung formed as a result of the aortic arch impressing or indenting the lung. (05 Mar 2000) |
| groove for the descending aorta | A broad, deep, vertical sulcus immediately posterior to the hilus on the mediastinal surface of the left lung, formed as a result of the descending aorta impressing or indenting the lung. (05 Mar 2000) |
| coarctation of the aorta | <cardiology, embryology, paediatrics> A congenital heart defect that results in the narrowing of the lumen of the aorta. The narrowing occurs most often distal to the origin of the left subclavian artery. Coarctation occurs in approximately 7% of patients with congenital heart disease and is twice as common in males. Surgical correction is most often required. Symptoms include headaches, dizziness, fainting, nosebleeds, diminished pulses in lower extremities and muscle cramps in legs with activity. There may be no symptoms in some individuals. (27 Sep 1997) |
| primitive aorta | The paired aortic primordia in young embryos. (05 Mar 2000) |
| pseudocoarctation of the aorta | A rare abnormality of the arch of the aorta that constricts that vessel but is not a true coarctation in that there is no significant encroachment on the lumen. (05 Mar 2000) |
| shaggy aorta | A colloquial but fitting description for severe arterial degeneration of the aorta, the surface of which is extremely friable and likely to cause atheroembolism. (05 Mar 2000) |
| descending aorta | A part of the aorta, further divided into the thoracic aorta and the abdominal aorta. Synonym: pars descendens aortae, aorta descendens, descending part of aorta. (05 Mar 2000) |
| descending part of aorta | A part of the aorta, further divided into the thoracic aorta and the abdominal aorta. Synonym: pars descendens aortae, aorta descendens, descending part of aorta. (05 Mar 2000) |
| dissecting thoracic aorta | <surgery> A condition in which a weakened portion of the thoracic aorta begins to tear along the longitudinal axis of the vessel. Symptoms include sudden, severe chest pain that may radiate to the back accompanied by nausea, sweating and difficulty breathing. A common risk factor for this event is atherosclerotic vascular disease and-or hypertension. Advanced cases of syphilis (syphilitic aortitis) can also result in acute thoracic dissection as a complication of infection with Treponema pallidum. (11 Jan 1998) |
| dynamic aorta | Abnormally marked pulsations of aorta. (05 Mar 2000) |
| isthmus of aorta | A slight constriction of the aorta immediately distal to the left subclavian artery at the point of attachment of the ductus arteriosus. Synonym: isthmus aortae. (05 Mar 2000) |
| oesophageal branches of the thoracic aorta | Branches arising directly from the anterior aspect of the portion of the thoracic aorta adjacent to the oesophagus, by which most of the oesophagus is supplied. Synonym: rami oesophageales aortae thoracicae. (05 Mar 2000) |
