Pathological processes of CORONARY ARTERIES that may derive from a congenital abnormality, atherosclerotic, or non-atherosclerotic cause.

An imbalance between myocardial functional requirements and the capacity of the CORONARY VESSELS to supply sufficient blood flow. It is a form of MYO…

Complete blockage of blood flow through one of the CORONARY ARTERIES, usually from CORONARY ATHEROSCLEROSIS.

Recurrent narrowing or constriction of a coronary artery following surgical procedures performed to alleviate a prior obstruction.

Narrowing or constriction of a coronary artery.

The label is process-shaped, but the organ-specific concept may also function as a disorder; manual semantic review is required.

Spasm of the large- or medium-sized coronary arteries.

Malformations of CORONARY VESSELS, either arteries or veins. Included are anomalous origins of coronary arteries; ARTERIOVENOUS FISTULA; CORONARY ANE…

A complication of INTERNAL MAMMARY-CORONARY ARTERY ANASTOMOSIS whereby an occlusion or stenosis of the proximal SUBCLAVIAN ARTERY causes a reversal o…

A developmental malformation of the heart characterized by a twisted but not defective atrioventicular connection. The abnormal rotation of the ventr…

A condition characterized by the presence of abnormal quantities of CRYOGLOBULINS in the blood. Upon cold exposure, these abnormal proteins precipita…

Primarily an observable or examinable clinical manifestation rather than a disease entity.

Unexpected rapid natural death due to cardiovascular collapse within one hour of initial symptoms. It is usually caused by the worsening of existing …

An abnormal balloon- or sac-like dilatation in the wall of the DESCENDING THORACIC AORTA.

A congenital defect in which the heart is located on the right side of the THORAX instead of on the left side (levocardia, the normal position). When…

VASCULAR DISEASES that are associated with DIABETES MELLITUS.

Diabetes complications in which VENTRICULAR REMODELING in the absence of CORONARY ATHEROSCLEROSIS and hypertension results in cardiac dysfunctions, t…

Common foot problems in persons with DIABETES MELLITUS, caused by any combination of factors such as DIABETIC NEUROPATHIES; PERIPHERAL VASCULAR DISEA…

A type of constriction that is caused by the presence of a fibrous ring (discrete type) below the AORTIC VALVE, anywhere between the aortic valve and…

Dissection or a tear of the ABDOMINAL AORTA. It includes thoracoabdominal aortic dissection at the aortic hiatus.

A separation of the layers within the wall of the ascending aorta. Tears in the intimal layer result in the propagation of dissection (proximally or …

A tear or separation of the layers by a blood vessel typically involving vessels under pressure, i.e., ARTERIES, e.g., AORTA. Tearing of the TUNICA I…

Dissection or a tear of the THORACIC AORTA. It includes aortic root dissection, ascending aortic dissection, aortic arch dissection and descending th…

Incomplete transposition of the great vessels in which both the AORTA and the PULMONARY ARTERY arise from the RIGHT VENTRICLE. The only outlet of the…

A congenital heart defect characterized by the persistent opening of fetal DUCTUS ARTERIOSUS that connects the PULMONARY ARTERY to the descending aor…

A congenital heart defect characterized by downward or apical displacement of the TRICUSPID VALVE, usually with the septal and posterior leaflets bei…

A rare developmental defect in which the heart is abnormally located partially or totally outside the THORAX. It is the result of defective fusion of…

Abnormal fluid retention by the body due to impaired cardiac function or heart failure. It is usually characterized by increase in venous and capilla…

A heterogeneous group of autosomally inherited COLLAGEN DISEASES caused by defects in the synthesis or structure of FIBRILLAR COLLAGEN. There are num…

A subtype of Ehlers-Danlos syndrome (EDS) characterized by vascular pathologies, e.g., AORTIC DISSECTION in addition to common EDS findings, e.g., hy…
