|
|
Term
| Non-infective (Marantic) Endocarditis |
|
Definition
| Nonbacterial thrombic endocarditis (NBTE) or marantic endocarditis is most commonly found on previously undamaged valves. As opposed to infective endocarditis, the vegetations in NBTE are small, sterile, and tend to aggregate along the edges of the valve or the cusps. Also unlike infective endocarditis, NBTE does not cause an inflammation response from the body (confusing, as the suffix "-itis" refers to inflammation). NBTE usually occurs during a hypercoagulable state. |

|
Term
|
Definition
| Rheumatic heart disease is a condition in which permanent damage to heart valves is caused by rheumatic fever. The heart valve is damaged by a disease process that generally begins with a strep throat caused by bacteria called Streptococcus, and may eventually cause rheumatic fever |

|
|
Term
|
Definition
| A congenital anomaly of the heart consisting of pulmonary stenosis, interventricular septal defect, dextroposed aorta that receives blood from both ventricles, and hypertrophy of the right ventricle.<br /> |
|
|
Term
| Transpositon of the great vessels |
|
Definition
| A fetal deformity of the heart in which the aorta arises from the right ventricle and the pulmonary artery arises from the left ventricle. <br /> |
|
|
Term
|
Definition
| Truncus arteriosus is a rare type of congenital heart disease in which a single blood vessel (truncus arteriosus) comes out of the right and left ventricles, instead of the normal two (pulmonary artery and aorta).<br /> |
|
|
Term
|
Definition
| Unstable angina is a condition in which your heart doesn't get enough blood flow and oxygen. It may be a prelude to a heart attack.<br /><br />Angina is a type of chest discomfort caused by poor blood flow through the blood vessels (coronary vessels) of the heart muscle (myocardium).<br /><br /> |
|
|
Term
|
Definition
| results from valve leaflets not completely sealing when a valve is closed so that regurgitation of blood occurs (backward flow of blood) into the proximal cardiac chamber. |
|
|
Term
|
Definition
| A backflow of blood through a valve, esp. a heart valve, that is not completely closed as it would normally be.<br /> |
|
|
Term
|
Definition
| a narrowing or stricture of any of the heart valves. The condition may result from a congenital defect or may be caused by disease |
|
|
Term
|
Definition
| A morbid luxurious outgrowth on any part, esp. wartlike projections made up of collections of fibrin in which are enmeshed white and red blood cells; sometimes seen on denuded areas of the endocardium covering the valves of the heart.<br /> |
