Bicuspid aortic valve (BAV) is a form of heart disease in which two of the leaflets of the aortic valve fuse during development in the womb resulting in a two-leaflet (bicuspid) valve instead of the normal three-leaflet (tricuspid) valve. BAV is the most common cause of heart disease present at birth and affects approximately 1.3% of adults. [2 ...
Valvular heart disease resulting from rheumatic fever is referred to as rheumatic heart disease. Acute rheumatic fever, which frequently manifests with carditis and valvulitis, [ 20 ] is a late sequela of Group A beta-hemolytic streptococcus infection in the throat, often lagging the initial infection by weeks to months.

A quadricuspid aortic valve (QAV) is a rare congenital heart defect characterized by the presence of four cusps, instead of the usual three found normally in the aortic valve. [1] It is a defect that occurs during embryological development of the aortic trunk during gestation. [2] There is an increased risk of developing post-natal aortic ...
Aortic valve stenosis is the most common cause of LVOTO. Aortic valve stenosis means the aortic valve has narrowed and is not opening freely. The aortic valve opens to allow blood to flow from the left ventricle to the aorta. Stenosis here leads to a narrowing of the passage for blood to flow out of the left ventricle, thus a LVOTO.
A double inlet left ventricle (DILV) or "single ventricle", is a congenital heart defect appearing in 5 in 100,000 newborns, where both the left atrium and the right atrium feed into the left ventricle. The right ventricle is hypoplastic or does not exist. Both atria communicate with the ventricle by a single atrio-ventricular valve.
Valvular heart disease Your heart valves control the way blood flows in and out of your heart and through the four chambers of your heart. It affects about 2.5% of people in the United States.
Children typically have good cardiac function and survival after the Yasui procedure, similar to other operations for the same conditions. However, children may require re-operation to replace the conduit in their heart if they outgrow it. Long-term survival depends on other factors, such as genetic disease. [2] [5] [6]
Pulmonic stenosis is usually due to isolated valvular obstruction (pulmonary valve stenosis), but it may be due to subvalvular or supravalvular obstruction, such as infundibular stenosis. It may occur in association with other congenital heart defects as part of more complicated syndromes (for example, tetralogy of Fallot). [citation needed]
