The acquired valvular heart disease
The acquired valvular heart disease Valvular heart disease refers to any dysfunction or abnormality of one or more of the heart’s four valves: the mitral, tricuspid, aortic, and pulmonary valves. While some valvular conditions are congenital, a significant portion of cases are acquired during an individual’s lifetime. Acquired valvular heart disease (AVHD) often results from various factors such as infections, degenerative changes, rheumatic fever, or other pathological processes that damage the structure and function of the valves.
The most common etiologies of AVHD include rheumatic heart disease and degenerative calcific disease. Rheumatic fever, which typically follows untreated streptococcal infections, leads to inflammation and scarring of the valves, most frequently affecting the mitral valve. Over time, this scarring can cause stenosis (narrowing) or regurgitation (leakage), impairing normal blood flow. Degenerative calcific changes tend to occur with aging, predominantly affecting the aortic valve, leading to calcific aortic stenosis—a condition characterized by stiff, narrowed valves that obstruct blood flow from the heart to the body.

In addition to rheumatic and degenerative causes, other factors contributing to AVHD include infective endocarditis, which involves infection and destruction of valve tissue; radiation therapy that damages valvular structures; systemic illnesses such as lupus or rheumatoid arthritis that can cause inflammation; and iatrogenic causes like valve injury from procedures. Each of these conditions can alter the integrity and functionality of the valves, leading to varying degrees of stenosis or regurgitation. The acquired valvular heart disease
The acquired valvular heart disease The clinical presentation of acquired valvular disease varies depending on the severity and type of valve involvement. Mild cases may be asymptomatic and only detected incidentally during routine examinations. However, as the disease progresses, patients may experience symptoms such as shortness of breath, fatigue, palpitations, chest pain, or even signs of heart failure, including swelling in the legs or pulmonary congestion. Auscultation often reveals characteristic murmurs indicative of turbulent blood flow across defective valves.
Diagnosis involves a combination of clinical assessment and imaging studies. Echocardiography remains the cornerstone for evaluating valvular structure and function, providing detailed information about the severity of stenosis or regurgitation, the degree of valve calcification, and the impact on cardiac chambers. Additional tests like electrocardiograms, chest X-rays, and cardiac MRI can assist in assessing secondary effects on the myocardium and pulmonary vasculature.

Medical therapy aims to alleviate symptoms and prevent complications—diuretics for pulmonary congestion, anticoagulants in certain regurgitant conditions, and antibiotics for infective endocarditis. Nevertheless, definitive treatment often involves surgical intervention, including valve repair or replacement. Advances in prosthetic valves and minimally invasive procedures have improved outcomes and quality of life for affected patients.
Preventing acquired valvular heart disease hinges on controlling risk factors—timely treatment of streptococcal infections, managing systemic illnesses, and minimizing exposure to radiation or cardiotoxic drugs. Early detection and intervention are key to preventing progression and complications, emphasizing the importance of routine health check-ups and awareness of symptoms.
The acquired valvular heart disease In conclusion, acquired valvular heart disease poses a significant health burden worldwide. Understanding its causes, clinical features, and treatment options enables better management and improved prognosis for affected individuals. As research advances, newer therapies and interventions continue to enhance patient outcomes, offering hope for those living with this complex condition.
