The valvular heart disease rheumatic fever
The valvular heart disease rheumatic fever Valvular heart disease resulting from rheumatic fever remains a significant health concern in many parts of the world, especially where access to prompt medical care is limited. Rheumatic fever is an inflammatory disease that develops as a complication of untreated or inadequately treated group A streptococcal pharyngitis, commonly known as strep throat. If not properly managed, rheumatic fever can cause lasting damage to the heart valves, leading to a condition known as rheumatic valvular heart disease.
The valvular heart disease rheumatic fever The pathogenesis of rheumatic heart disease involves an autoimmune response. After an initial infection with streptococcus bacteria, the immune system mistakenly attacks the body’s own tissues, including the heart valves. This immune-mediated inflammation primarily targets the mitral and aortic valves, causing thickening, fibrosis, and deformity. Over time, these changes can result in stenosis (narrowing of the valve opening), regurgitation (leakage of blood backward through the valve), or a combination of both. The mitral valve is most frequently affected, often leading to mitral stenosis, which can cause symptoms such as breathlessness, fatigue, and palpitations.
Clinically, rheumatic valvular disease often has a delayed presentation, sometimes appearing years after the initial episode of rheumatic fever. Patients may remain asymptomatic in early stages, but as the valve damage progresses, signs of heart failure, such as pulmonary congestion, edema, and atrial fibrillation, may develop. Auscultation typically reveals murmurs characteristic of stenosis or regurgitation, guiding further diagnostic evaluation.
Diagnosis involves a combination of clinical history, physical examination, and echocardiography. The Jones Criteria are often used for diagnosing rheumatic fever, emphasizing evidence of preceding streptococcal infection alongside clinical features. Echocardiography provides visual confirmation of valve thickening, mobility restriction, and the severity of stenosis or regurgitation, which are crucial in planning treatment.

Management strategies focus on both treating the active inflammatory process and preventing further cardiac damage. Antibiotics, particularly penicillin, are used to eradicate streptococcal infection and prevent recurrent attacks. Anti-inflammatory medications like aspirin or corticosteroids help reduce inflammation during acute episodes. For established valvular damage, medical management aims to control symptoms and prevent complications, including arrhythmias and heart failure.
In severe cases, surgical intervention may be necessary. Valve repair or replacement becomes vital when valvular stenosis or regurgitation significantly impairs cardiac function. Advances in prosthetic valve technology have improved surgical outcomes, but the risk of complications such as thrombosis and endocarditis persists. The valvular heart disease rheumatic fever
The valvular heart disease rheumatic fever Preventing rheumatic fever is paramount and hinges on early detection and treatment of streptococcal infections, coupled with public health measures that improve access to healthcare. Education about the importance of completing antibiotic courses and seeking prompt medical attention for sore throats can significantly reduce the incidence of rheumatic fever and its long-term consequences, including valvular heart disease.
