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.

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.
BAV is the most common cause of heart disease present at birth and affects approximately 1.3% of adults. [2] Normally, the mitral valve is the only bicuspid valve and this is situated between the heart's left atrium and left ventricle. Heart valves play a crucial role in ensuring the unidirectional flow of blood from the atria to the ventricles ...
Pulmonary valve stenosis (PVS) is a heart valve disorder. Blood going from the heart to the lungs goes through the pulmonary valve, whose purpose is to prevent blood from flowing back to the heart. In pulmonary valve stenosis this opening is too narrow, leading to a reduction of flow of blood to the lungs. [1] [5]
Parachute mitral valve is commonly associated with other congenital heart disease. A 2004 study finds that children with PMV are 68% likely to have aortic coarctation, 54% likely to have an atrial septal defect, 46% likely to have a ventricular septal defect, and 19% likely to have left ventricular hypoplasia. [2] Parachute mitral valve is also ...
Top health researchers from the Murdoch Children’s Research Institute (MCRI) in Australia have teamed with those from the Gladstone Institutes in San Francisco on the Decoding Broken Hearts ...
This can lead to cardiac hypertrophy, dilatation of the heart, and ultimately heart failure in some cases. [1] The right side of the heart is much smaller and weaker than the left side of the heart. It pumps de-oxygenated blood into the lungs. The left side of the heart is more muscular than the right side of the heart.
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.
