Heart Murmur
The main sign of heart valve disease is a heart murmur. A murmur is an extra sound made when blood flows through a damaged valve. It often sounds like a “whoosh” or “swish.” Murmurs can be soft or loud and may sound different depending on the valve problem. Not all heart murmurs are caused by valve problems.
A healthcare provider can hear heart murmurs with a stethoscope (a tool used to listen to heart and lung sounds).
If symptoms are mild—like slight tiredness or lightheadedness—the provider may monitor closely with regular check-ups instead of starting medicines or surgery.
Other Symptoms
More serious symptoms of heart valve problems include:
- Severe tiredness
- Shortness of breath while resting
- Chest pain, pressure, tightness, or squeezing
- Racing, fluttering, or irregular heartbeat
- Swelling in the ankles, legs, or belly
- Dizziness or fainting
- Significant weight loss or weight gain
If you have any of these symptoms, contact your healthcare provider right away.
If the symptoms start suddenly, they could be a sign of acute heart failure, which is a medical emergency. If you can’t reach your provider, call 911.
