Label	Id	Description
Anus Diseases	D001004	[Diseases involving the ANUS.]
Anus Neoplasms	D001005	[Tumors or cancer of the ANAL CANAL.]
Anus, Imperforate	D001006	[A congenital abnormality characterized by the persistence of the anal membrane, resulting in a thin membrane covering the normal ANAL CANAL. Imperforation is not always complete and is treated by surgery in infancy. This defect is often associated with NEURAL TUBE DEFECTS; MENTAL RETARDATION; and DOWN SYNDROME.]
Aortic Aneurysm	D001014	[An abnormal balloon- or sac-like dilatation in the wall of AORTA.]
Aortic Aneurysm, Abdominal	D017544	[An abnormal balloon- or sac-like dilatation in the wall of the ABDOMINAL AORTA which gives rise to the visceral, the parietal, and the terminal (iliac) branches below the aortic hiatus at the diaphragm.]
Aortic Aneurysm, Thoracic	D017545	[An abnormal balloon- or sac-like dilatation in the wall of the THORACIC AORTA. This proximal descending portion of aorta gives rise to the visceral and the parietal branches above the aortic hiatus at the diaphragm.]
Aortic Arch Syndromes	D001015	[Conditions resulting from abnormalities in the arteries branching from the ASCENDING AORTA, the curved portion of the aorta. These syndromes are results of occlusion or abnormal blood flow to the head-neck or arm region leading to neurological defects and weakness in an arm. These syndromes are associated with vascular malformations; ATHEROSCLEROSIS; TRAUMA; and blood clots.]
Aortic Coarctation	D001017	[A birth defect characterized by the narrowing of the AORTA that can be of varying degree and at any point from the transverse arch to the iliac bifurcation. Aortic coarctation causes arterial HYPERTENSION before the point of narrowing and arterial HYPOTENSION beyond the narrowed portion.]
Aortic Diseases	D001018	[Pathological processes involving any part of the AORTA.]
Aortic Rupture	D001019	[The tearing or bursting of the wall along any portion of the AORTA, such as thoracic or abdominal. It may result from the rupture of an aneurysm or it may be due to TRAUMA.]
Aortic Stenosis, Subvalvular	D001020	[A pathological constriction occurring in the region below the AORTIC VALVE. It is characterized by restricted outflow from the LEFT VENTRICLE into the AORTA.]
Aortic Stenosis, Supravalvular	D021921	[A pathological constriction occurring in the region above the AORTIC VALVE. It is characterized by restricted outflow from the LEFT VENTRICLE into the AORTA.]
Aortic Valve Insufficiency	D001022	[Pathological condition characterized by the backflow of blood from the ASCENDING AORTA back into the LEFT VENTRICLE, leading to regurgitation. It is caused by diseases of the AORTIC VALVE or its surrounding tissue (aortic root).]
Aortic Valve Prolapse	D001023	[The downward displacement of the cuspal or pointed end of the trileaflet AORTIC VALVE causing misalignment of the cusps. Severe valve distortion can cause leakage and allow the backflow of blood from the ASCENDING AORTA back into the LEFT VENTRICLE, leading to aortic regurgitation.]
Aortic Valve Stenosis	D001024	[A pathological constriction that can occur above (supravalvular stenosis), below (subvalvular stenosis), or at the AORTIC VALVE. It is characterized by restricted outflow from the LEFT VENTRICLE into the AORTA.]
Aortitis	D001025	[Inflammation of the wall of the AORTA.]
Aortopulmonary Septal Defect	D001028	[A developmental abnormality in which the spiral (aortopulmonary) septum failed to completely divide the TRUNCUS ARTERIOSUS into ASCENDING AORTA and PULMONARY ARTERY. This abnormal communication between the two major vessels usually lies above their respective valves (AORTIC VALVE; PULMONARY VALVE).]
Ape Diseases	D018420	[Diseases of chimpanzees, gorillas, and orangutans.]
Aphakia	D001035	[Absence of crystalline lens totally or partially from field of vision, from any cause except after cataract extraction. Aphakia is mainly congenital or as result of LENS DISLOCATION AND SUBLUXATION.]
Aphakia, Postcataract	D001036	[Absence of the crystalline lens resulting from cataract extraction.]
