Heart Defects, Congenital

Medical Definition: Imperfections or malformations of the heart, existing at birth.
Guide Notes: GEN only; do not use as coord for specific term /abnorm; cyanotic defects probably go here but do not also index under CYANOSIS unless especially discussed
Also Called: Ectopia Cordis
Heart Defects, Congenital Categories.
Canadian Medical Guide Definition Aortic Coarctation - Narrowing of the lumen of the aorta, caused by deformity of the aortic media.
Canadian Medical Guide Definition Arrhythmogenic Right Ventricular Dysplasia - A congenital cardiomyopathy in which transmural infiltration of adipose tissue results in weakness and aneurysmal bulging of the infundibulum, apex, and posterior basilar region of the right ventricle and leads to ventricular tachycardia arising in the right ventricle. (Dorland, 28th ed)
Canadian Medical Guide Definition Cor Triatriatum - A congenital anomaly characterized by the presence in the atrium of a perforated muscular membrane which separates the atrium into upper and lower chambers.
Canadian Medical Guide Definition Coronary Vessel Anomalies - Defects of coronary arteries or veins including anomalous origin, arteriovenous fistula or aneurysm, myocardial bridging, or other abnormalities of structure or development.
Canadian Medical Guide Definition Crisscross Heart - Cardiac malformation characterized by an atrioventricular spatial relation that places or appears to place each ventricle in a contralateral position relative to its associated atrium.
Canadian Medical Guide Definition Dextrocardia - Location of the heart in the right hemithorax, with the apex directed to the right.
Canadian Medical Guide Definition Ductus Arteriosus, Patent - Abnormal persistence of an open lumen in the ductus arteriosus after birth, the direction of flow being from the aorta to the pulmonary artery, resulting in recirculation of arterial blood through the lungs. (Dorland, 27th ed)
Canadian Medical Guide Definition Ebstein's Anomaly - Congenital downward displacement of the tricuspid valve with the septal and posterior leaflets being attached to the wall of the right ventricle.
Canadian Medical Guide Definition Eisenmenger Complex - Defect of the interventricular septum with severe pulmonary hypertension, hypertrophy of the right ventricle, and latent or overt cyanosis.
Canadian Medical Guide Definition Heart Septal Defects - Defects in the cardiac septa, resulting in abnormal communications between the opposite chambers of the heart.
Canadian Medical Guide Definition Hypoplastic Left Heart Syndrome - A condition characterized by underdevelopment of the left cardiac chambers, atresia or stenosis of the aorta or mitral valve or both, and hypoplasia of the aorta. These anomalies are a common cause of heart failure in early infancy.
Canadian Medical Guide Definition Levocardia - Location of heart in left hemithorax with apex pointing to the left, but with situs inversus of other viscera and defects of the heart, or corrected transposition of great vessels.
Canadian Medical Guide Definition Tetralogy of Fallot - A combination of congenital cardiac defects consisting of pulmonary stenosis, interventricular septal defects, dextroposition of the aorta so that it overrides the interventricular septum and receives venous as well as arterial blood, and right ventricular hypertrophy.
Canadian Medical Guide Definition Transposition of Great Vessels - A congenital cardiovascular malformation in which the aorta arises entirely from the right ventricle and the pulmonary artery from the left ventricle, so that the venous return from the peripheral circulation is recirculated by the right ventricle via the aorta to the systemic circulation without being oxygenated in the lungs.
Canadian Medical Guide Definition Tricuspid Atresia - Absence of the orifice between the right atrium and ventricle, with the presence of an atrial defect through which all the systemic venous return reaches the left heart. As a result, there is left ventricular hypertrophy (HYPERTROPHY, LEFT VENTRICULAR) because the right ventricle is absent or not functional.
Canadian Medical Guide Definition Truncus Arteriosus, Persistent - A congenital anomaly resulting from the failure of the aorticopulmonary system to develop and divide the truncus arteriosus into the aorta and the pulmonary trunk.
