Lesions that form on heart valves after damage by infection?
These lesions are typically caused by bacterial infections, leading to conditions such as endocarditis. The infected tissue on the heart valves may form vegetations, which can impede blood flow and increase the risk of complications like valve regurgitation or embolism. Treatment often involves antibiotics and, in severe cases, surgical repair or replacement of the damaged valve.
How does the disease affect the heart's mitral valve with RHD?
This infection causes swelling and muscle damage to the heart. It can also damage the heart valves in a way that keeps the blood from moving through the heart normally. The infection can cause heart valve leaflets to stick together, which narrows the valve opening. Also, the infection can scar the valves.
What is the disease caused by streptococcal infection causing damage to the heart valves and heart muscle?
The disease is called rheumatic heart disease. It is an autoimmune disease that follows an untreated bout of pharyngitis (sore, inflamed throat) caused by an infection with the bacteria Streptococcus pyogenes.
What is the purpose of heart valve repair?
To correct damage to the mitral, aortic, pulmonary, or tricuspid heart valves caused by a systemic infection, endocarditis, rheumatic heart disease, a congenital heart defect, or mitral and/or aortic valve disease.
Does rheumatic heart disease result from staph infection?
No, rheumatic heart disease does not result from a staph infection. It is a complication of rheumatic fever, which is primarily caused by an infection with group A Streptococcus bacteria, typically following strep throat or scarlet fever. The body's immune response to the streptococcal infection can lead to inflammation in the heart, joints, skin, and brain, ultimately causing damage to the heart valves.
What impact does the C.fetus subtype of the Campylobacter bacteria have on vessels and heart valves?
Infection of vessels and heart valves is a special characteristic of C. fetus.
What is valvulitis?
Commonly associated with rheumatic fever, an inflammatory disease caused by inadequate treatment of a streptococcal infection. An autoimmune reaction occurs, leading to inflammation and damage to heart valves.
What is mitral valvulitis?
Commonly associated with rheumatic fever, an inflammatory disease caused by inadequate treatment of a streptococcal infection. An autoimmune reaction occurs, leading to inflammation and damage to heart valves.
How does rheumatic fever attack the body?
It does serious damage to the valves in the Heart.
How could damage to the heart valves lead to a backup of blood?
Damage to heart valves would cause backflow of the blood meaning the heart would be unable to supply parts of the body with oxygen. In serious cases this could lead to stoke or heart attacks.
Why is endocarditis serious?
Endocarditis is serious because it can lead to complications such as heart valve damage, heart failure, stroke, or sepsis, and can be life-threatening if not promptly treated. The infection affects the inner lining of the heart chambers and valves, which can interfere with blood flow and potentially cause serious cardiac issues. Treatment often requires intravenous antibiotics or surgery to repair damaged heart valves.
What is the acute bacterial infection whose toxins can damage the heart muscle and peripheral nerves?
