Heart Condition

Valvular Heart Disease

Valvular heart disease occurs when one or more of the four heart valves do not work properly, either because a valve is narrowed and does not open fully (stenosis) or does not close completely and leaks (regurgitation). This makes the heart work harder and, over time, can lead to symptoms, heart strain and heart failure.

01Symptoms

Common signs and symptoms associated with Valvular Heart Disease include:

  • Breathlessness, especially on exertion or when lying flat
  • Tiredness and reduced exercise tolerance
  • Palpitations or an irregular heartbeat
  • Swelling of the ankles or feet
  • Dizziness or fainting
  • A heart murmur heard on examination

02Causes & Risk Factors

  • Age-related wear and calcium build-up on the valves
  • A valve abnormality present from birth
  • Previous rheumatic fever
  • Infection of a heart valve (endocarditis)
  • Heart muscle disease or a previous heart attack

03When To See A Cardiologist

See a cardiologist if you develop breathlessness, swelling of the legs, reduced exercise tolerance, or if a heart murmur has been noted. Valve disease can progress silently, so periodic review is important once it is known. Severe breathlessness, chest pain or fainting are emergencies, call 995.

04Treatment Approaches At CCI

At CCI, valve problems are assessed with transthoracic echocardiography, which shows how each valve is opening and closing, supported by other tests as needed, including transesophageal echo. Mild disease is monitored over time, while more significant disease is managed with medication and, when appropriate, referral for valve repair or replacement. Dr Lee also manages the heart rhythm problems that can accompany valve disease.

Common Questions

Frequently Asked Questions

How is valvular heart disease detected?

An echocardiogram is the key test, showing each valve in motion and measuring how well it opens and closes. A murmur on examination often prompts this scan.

Does every leaky or narrowed valve need surgery?

No. Many people with mild valve disease simply need regular monitoring. Surgery or a procedure is considered when the disease becomes significant or causes symptoms.

Can valve disease cause an irregular heartbeat?

Yes. Valve disease puts stress on heart and can lead to rhythm problems such as atrial fibrillation, which Dr Lee, as a cardiac electrophysiologist, is well placed to manage.
