The rheumatic valvular heart disease
The rheumatic valvular heart disease Rheumatic valvular heart disease is a chronic condition resulting from rheumatic fever, an inflammatory disease that can develop after an infection with group A streptococcus bacteria. Although rheumatic fever is now less common in developed countries due to improved living conditions and widespread antibiotic use, it remains a significant health concern in many developing regions. This disease primarily affects the heart valves, leading to their damage and subsequent functional impairment.
The rheumatic valvular heart disease The pathogenesis of rheumatic valvular disease begins with an immune response triggered by streptococcal infection. The immune system, in its effort to fight the bacteria, inadvertently attacks the body’s own tissues, especially the connective tissue of the heart valves. Over time, repeated episodes of rheumatic fever can cause progressive inflammation, fibrosis, and scarring of the valves. The mitral valve is most frequently affected, followed by the aortic valve, although other valves can also be involved.
Clinically, patients with rheumatic valvular disease may remain asymptomatic for years or present with signs of valvular dysfunction. Common symptoms include shortness of breath during exertion, fatigue, palpitations, and in advanced cases, symptoms of heart failure such as edema and orthopnea. Auscultation often reveals characteristic murmurs: a mitral stenosis murmur, which is a low-pitched, diastolic sound best heard at the apex with the bell of the stethoscope, and aortic regurgitation murmurs, which are usually high-pitched and heard best along the left sternal border.

The rheumatic valvular heart disease Diagnosis relies heavily on clinical history, echocardiography, and laboratory tests. Echocardiography is crucial in assessing the severity of valvular damage, visualizing valve morphology, and detecting complications such as thrombus formation or pulmonary hypertension. Blood tests may show elevated inflammatory markers during active rheumatic fever episodes and evidence of previous streptococcal infection through antistreptolysin O titers.
Management of rheumatic valvular disease involves both medical and surgical approaches. During the acute phase of rheumatic fever, anti-inflammatory medications like aspirin or corticosteroids are used to control inflammation. Long-term antibiotic prophylaxis, often with penicillin, is essential to prevent recurrent streptococcal infections, thereby reducing the risk of further valvular damage. For patients with significant valvular stenosis or regurgitation causing symptoms or complications, surgical intervention becomes necessary. Valve repair or replacement procedures can significantly improve quality of life and survival rates. The rheumatic valvular heart disease
Prevention is a key aspect in controlling rheumatic valvular disease. Early diagnosis and prompt treatment of streptococcal pharyngitis are vital in preventing the progression to rheumatic fever. Public health measures, including improved sanitation, education about sore throat management, and access to healthcare, play a pivotal role in reducing disease incidence.
In conclusion, rheumatic valvular heart disease remains a preventable yet serious condition that can lead to significant morbidity if not managed appropriately. Advances in diagnostic tools and surgical techniques have improved outcomes, but prevention strategies continue to be the most effective way to reduce its global burden.
