Valvular heart disease

Valvular heart disease refers to structural or functional changes in one or more of the heart’s valves. Causes and clinical course vary; diagnosis and long‑term follow‑up are usually managed by cardiology. The information below is for general education and specialty direction, not personalized medical advice.

What it is and common causes

Valve problems occur when a valve becomes narrowed (stenosis), leaks (regurgitation) or both. Frequent causes include damage from prior rheumatic fever, age‑related degenerative changes, infective endocarditis, congenital valve abnormalities and trauma. When inflammation or infection is suspected, evaluation for infectious causes and inflammatory processes is important.

Symptoms and impact on daily life

Typical symptoms include exertional breathlessness, early fatigue, palpitations, chest discomfort and, less commonly, fainting or near‑syncope. These symptoms can reduce exercise capacity and quality of life depending on the valve involved and the severity. Decisions about sport, exercise intensity or dietary supplements (for example creatine‑containing protein powders) should be discussed with your cardiologist, especially if you are on regular prophylactic injections or have other cardiac follow‑up.

Diagnosis and which specialists to see

Assessment usually starts with medical history and physical exam. Key diagnostic tests include transthoracic echocardiography and, if needed, transesophageal echocardiography. ECG, chest X‑ray, exercise testing and advanced imaging may be used. Initial contact can be with primary care or directly to cardiology. If infection is suspected, an Infectious Diseases specialist may be involved; cases needing surgery require referral to Cardiac Surgery.

Monitoring, risks and urgent signs

Many valve disorders require periodic monitoring with repeat imaging and clinical review to detect progression or complications. Seek urgent medical attention if you experience sudden severe breathlessness, new or severe chest pain, loss of consciousness or repeated fainting, sudden marked swelling of the legs, or changes in mental status. These situations warrant immediate evaluation in an emergency setting.

Work fitness, military service and official evaluations

Decisions about fitness for work, military service or other official processes depend on the valve lesion, its severity, functional capacity and objective test results. Medical boards typically rely on cardiology reports, echocardiogram findings and exercise testing where relevant. Ask your cardiologist for up‑to‑date reports and recommended tests when preparing documentation.
