Rheumatic heart disease is associated with valvular stenosis
Rheumatic heart disease is associated with valvular stenosis Rheumatic heart disease (RHD) remains a significant public health concern, especially in developing regions. It is a chronic heart condition resulting from rheumatic fever, which is an inflammatory disease that can develop after untreated or inadequately treated streptococcal throat infections. A central feature of RHD involves damage to the heart valves, notably leading to valvular stenosis, a condition characterized by narrowing of the heart valves that impairs normal blood flow.
The pathogenesis of rheumatic heart disease begins with an immune response triggered by a streptococcal infection. The immune system, in its attempt to eradicate the bacteria, mistakenly targets the body’s own tissues, including the heart valves. This autoimmune reaction results in inflammation and scarring of the valve leaflets and supporting structures. Over time, repeated episodes of rheumatic fever can cause progressive damage, leading to permanent deformities. Rheumatic heart disease is associated with valvular stenosis
Rheumatic heart disease is associated with valvular stenosis Valvular stenosis in RHD primarily affects the mitral valve, which is most commonly involved, followed by the aortic valve. The inflammatory process causes leaflet thickening, fusion of commissures, and sometimes calcification. These changes hinder the valves’ ability to open fully during systole, resulting in obstructed blood flow from the atria to the ventricles. The clinical manifestations of valvular stenosis include breathlessness, fatigue, palpitations, and in severe cases, pulmonary hypertension and right heart failure due to increased pressures in the pulmonary circulation.
The severity of valvular stenosis can vary widely, from mild to critical, depending on the extent of damage. Diagnostic evaluation involves echocardiography, which provides detailed visualization of valve morphology and hemodynamic assessments. Echocardiographic findings such as leaflet thickening, restricted mobility, and increased transvalvular gradients confirm the diagnosis and help gauge disease severity.
Management of rheumatic valvular stenosis involves both medical and surgical interventions. Medical therapy aims to control symptoms, prevent recurrent rheumatic fever episodes, and manage complications. This includes the use of diuretics, vasodilators, and prophylactic antibiotics to prevent streptococcal infections. However, in cases where stenosis causes significant hemodynamic compromise or leads to heart failure, surgical intervention becomes necessary. Valve repair or replacement, often via open-heart surgery, can restore normal blood flow and improve patient prognosis. Rheumatic heart disease is associated with valvular stenosis

Early diagnosis and treatment of streptococcal pharyngitis with antibiotics can prevent the initial onset of rheumatic fever. Additionally, secondary prophylaxis with long-term antibiotics is crucial for individuals with a history of rheumatic fever to prevent recurrences and further valvular damage.
In conclusion, rheumatic heart disease’s association with valvular stenosis underscores the importance of early intervention, effective management, and preventive strategies to mitigate its long-term impact. As a preventable condition, public health efforts focusing on timely treatment of streptococcal infections and ongoing patient support can significantly reduce the burden of this disease worldwide.
