Many heart valve problems are first identified by the presence of a “murmur” or sound that can be heard when a healthcare provider listens to the heartbeat with a stethoscope. A murmur may sound like a “whooshing” noise of blood flowing under pressure as it moves from one chamber to the next, or it may sound like an extra click when a valve allows back flow.
Some murmurs are harmless, and others can indicate an underlying problem with the valve. If you or your healthcare provider notice a murmur, here are some of the things he/she may be looking into further.
Murmurs may indicate valve problems including:
- Stenosis: a narrowing or stiffening of the valve that prevents adequate blood supply from flowing through
- Regurgitation: when valves allow blood to flow backward into the chamber
- Prolapse: a valve that has improperly closing leaflets
- Atresia: a valve that is improperly formed or missing
The causes of valve problems can often be linked to birth abnormalities, related to age, or brought on by another condition.
- Calcification due to aging — Sometimes calcium can accumulate on the heart's valves, most commonly affecting the aortic valve, and can lead to aortic stenosis.
Related illnesses and conditions that can cause valve problems:
These conditions can cause one or more of the heart valves to leak blood back into the heart chambers or fail to open fully, making your heart work harder and lessening its ability to pump blood. Although valve problems can potentially be severe and life-threatening, most valve conditions are also highly treatable.
