Pathological processes involving any part of the AORTA.

A tear in the inner layer of the AORTA leading to interstitial HEMORRHAGE, and splitting (dissecting) of the aortic TUNICA MEDIA layer. It typically …

An atypical form of AORTIC DISSECTION in which subintimal dissection of the aortic TUNICA MEDIA without initial laceration of the aortic TUNICA INTIM…

An abnormal balloon- or sac-like dilatation in the wall of the AORTIC ROOT.

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 i…

A pathological constriction occurring in the region below the AORTIC VALVE. It is characterized by restricted outflow from the LEFT VENTRICLE into th…

Diseases involving the AORTIC VALVE functionality. Aortic valve disease often results in a backward and/or regurgitated blood flow into the LEFT VENT…

Pathological condition characterized by the backflow of blood from the ASCENDING AORTA back into the LEFT VENTRICLE, leading to regurgitation. It is …

The downward displacement of the cuspal or pointed end of the trileaflet AORTIC VALVE causing misalignment of the cusps. Severe valve distortion can …

A pathological constriction that can occur above (supravalvular stenosis), below (subvalvular stenosis), or at the AORTIC VALVE. It is characterized …

Congenital anomaly characterized by an extra-cardiac channel connecting the AORTA either to the right or left HEART VENTRICLE.

Inflammation of the wall of the AORTA.

A developmental abnormality in which the spiral (aortopulmonary) septum failed to completely divide the TRUNCUS ARTERIOSUS into ASCENDING AORTA and P…

A hypertrophic cardiomyopathy characterized by apical hypertrophy, typically LEFT VENTRICULAR HYPERTROPHY (described as ace of spades sign), and deep…

Irregular HEART RATE caused by abnormal function of the SINOATRIAL NODE. It is characterized by a greater than 10% change between the maximum and the…

Any disturbances of the normal rhythmic beating of the heart or MYOCARDIAL CONTRACTION. Cardiac arrhythmias can be classified by the abnormalities in…

A congenital cardiomyopathy that is characterized by infiltration of adipose and fibrous tissue into the RIGHT VENTRICLE wall and loss of myocardial …

Pathological processes which result in the partial or complete obstruction of ARTERIES. They are characterized by greatly reduced or absence of blood…

Abnormal communication between two ARTERIES that may result from injury or occur as a congenital abnormality.

Thickening of the walls of small ARTERIES or ARTERIOLES due to cell proliferation or HYALINE deposition.

Thickening and loss of elasticity of the walls of ARTERIES of all sizes. There are many forms classified by the types of lesions and arteries involve…

Common occlusive arterial disease which is caused by ATHEROSCLEROSIS. It is characterized by lesions in the innermost layer (ARTERIAL INTIMA) of arte…

An abnormal direct communication between an artery and a vein without passing through the CAPILLARIES. An A-V fistula usually leads to the formation …

Abnormal formation of blood vessels that shunt arterial blood directly into veins without passing through the CAPILLARIES. They usually are crooked, …

INFLAMMATION of any ARTERIES.

A thickening and loss of elasticity of the walls of ARTERIES that occurs with formation of ATHEROSCLEROTIC PLAQUES within the ARTERIAL INTIMA.

Abnormal cardiac rhythm that is characterized by rapid, uncoordinated firing of electrical impulses in the upper chambers of the heart (HEART ATRIA).…

Rapid, irregular atrial contractions caused by a block of electrical impulse conduction in the right atrium and a reentrant wave front traveling up t…

A type of cardiac arrhythmia with premature atrial contractions or beats caused by signals originating from ectopic atrial sites. The ectopic signals…
