Heart murmurs can generally be divided into two categories: 1  Murmurs that are not due to structural problems in the heart also called innocent murmurs or functional murmurs..  Murmurs which are due to a structural problem of the heart (such as a hole in the heart, a narrowed heart valve or a leaky heart valve). These murmurs require further evaluation and follow-up with a cardiologist.
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. 3  Some murmurs are due to abnormal function of the valves in the heart. 4  The valves may have narrowing (stenosis) or they may leak (regurgitation). heart murmur is a continuous sound that is audible with a common stethoscope, produced when blood passes through particular areas of the heart. The heart has four chambers, two atria (singular = atrium) and two ventricles separated by a skeleton of cartilage that separates each chamber.
