Valvular heart disease
Encyclopedia
Valvular heart disease is any disease process involving one or more of the valves of the heart
(the aortic
and mitral valve
s on the left and the pulmonary
and tricuspid valves on the right). Valve problems may be congenital (inborn) or acquired (due to another cause later in life). Treatment may be with medication but often (depending on the severity) involves valve repair or replacement
(insertion of an artificial heart valve
). Specific situations include those where additional demands are made on the circulation, such as in pregnancy.
The most common types of pulmonary valve diseases are:
The International Statistical Classification of Diseases classifies non rheumatic pulmonary valve diseases as I37.
Both tricuspid and pulmonary valve diseases are less common than aortic
or mitral valve
diseases due to the lower pressure those valves experience.
Complications arise when the flow of blood is obstructed from leaving the right ventricle and making its way into the pulmonary artery, or once blood is in the pulmonary artery, the blood has the ability to flow back into the right ventricle. When blood has a difficult time making its way from the right ventricle into the pulmonary artery due to the pulmonary valve area being: Too narrow, deformed in some capacity (e.g., one of the leaflets of the valve is too thick, misshaped, or doesn't separate from another leaflet), or the vessel above or below the valve being deformed in such a way as to prevent the proper flow of blood, the term "pulmonary valve stenosis" is used.
is an error in the development of any of the heart valves, and a common cause of congenital heart defects in humans as well as animals; tetralogy of Fallot
is a congenital heart defect with four abnormalities, one of which is stenosis of the pulmonary valve. Ebstein's anomaly
is an abnormality of the tricuspid valve.
is referred to as "rheumatic heart disease". While developed countries once had a significant burden of rheumatic fever and rheumatic heart disease, medical advances and improved social conditions have dramatically reduced their incidence. Many developing countries, as well as indigenous populations within developed countries, still carry a significant burden of rheumatic fever and rheumatic heart disease and there has been a resurgence in efforts to eradicate the diseases in these populations. Inflammation of the heart valves due to any cause is called endocarditis
; this is usually due to bacterial infection but may also be due to cancer
(marantic endocarditis
), certain autoimmune conditions (Libman-Sacks endocarditis
) and hypereosinophilic syndrome
(Loeffler endocarditis
). Certain medications have been associated with valvular heart disease, most prominently ergotamine derivatives pergolide
and cabergoline
