What is a Heart murmur?
The heart’s noises are produced at the opening and closing of its valves, the murmurs are abnormal sounds produced by the abnormal circulation and friction of blood against malfunctioning structures within the heart or near the heart, the reasons for this to happen can vary, some of them can be:
- Malfunctioning cardiac valves.
- Holes on the cardiac walls.
- As the result of a corrective surgery of heart malformations.
How are these murmurs?
The doctor will evaluate many aspects of a murmur, he will assess about the sound volume, period duration and intensity
- Systolic murmur – It appears during a heart’s muscle contraction, can be of ejection (blood flowing through a narrowed vessel or an irregular valve) or regurgitation murmurs.
- Diastolic murmur – Heard during the heart’s muscle relaxation between two heart beatings, these murmurs are produced by mitral or tricuspid valves narrowing or by regurgitation of pulmonary or aortic valves.
- Continuous murmur – It is heard all along the cardiac cycle.
The cardiac murmurs can be congenital or acquired.
Are all the murmurs indicating a heart disease?
No, sometimes a murmur can be heard on the chest of a normal person with fever or anemia, these murmurs will disappear when the condition has gone.
Some kids may have a murmur known as innocent, this is not associated with any diseases and its usual to observe its disappearing in adulthood, maybe the doctor will ask you to perform some tests on the kid to make sure this is an innocent murmur, but it is relevant to study each patient because in some occasions the murmur can be related to a real cardiac disease.
Most of the cardiac diseases related to murmurs can be corrected either by catheter approach or by surgery.
