No, a heart murmur does not cause high blood pressure. A heart murmur is simply the sound of turbulent flow. It can be caused by valve dysfunction (failure of a valve to open or close completely).
Heart murmur facts. 1  Turbulent blood flow within the heart causes abnormal sounds called murmurs. 2  Most murmurs are functional, or physiologic, and are normal variants. They are often known as innocent murmurs. 3  Some murmurs are due to abnormal function of the valves in the heart. The valves may have narrowing (stenosis) or they may leak (regurgitation). Holes in the septum or wall that divides the atrium or ventricles (septal defects) may cause a murmur.
