Heart valve disease

Also called Valvular heart disease or Heart murmur

Heart valve disease is when one or more of the four valves in the heart do not work properly. A valve may become narrowed (stenosis), so it does not open fully, or leaky (regurgitation), so blood flows backwards. It is more common with age and may also be present from birth or follow an infection.

What it is

Mild valve disease often causes no symptoms and is monitored with regular scans.

Medicines can ease symptoms, and severe valve disease is treated by repairing or replacing the valve, through surgery or a catheter.

Common signs

  • Often no symptoms at first
  • Breathlessness
  • Chest pain
  • Tiredness
  • Dizziness or fainting
  • Swollen ankles

How it is usually diagnosed

  • Listening to the heart for a murmur
  • Echocardiogram
  • ECG
  • Cardiac MRI or CT, sometimes

Records worth keeping

Keeping these together makes each appointment easier, especially when you see a new doctor:

  • Echocardiogram reports over time
  • Cardiology letters
  • Valve surgery or procedure notes
  • Anticoagulation records, if on blood thinners

Questions to ask your doctor

  • Which valve is affected and how severely?
  • How often do I need a scan?
  • When would the valve need treatment?

When to get help right away

Call 112 or go to the nearest emergency department if you have:

  • Chest pain, fainting or sudden severe breathlessness: call 112
