A heart murmur is a sound of blood flowing through the heart the doctor picks up using a stethoscope. The normal sounds of the heart are made by the contraction of the ventricles and closing up of the heart valves. Besides these sounds, the doctor may hear a swishing sound, which is the heart murmur. Many healthy individuals do have a murmur that does not need to be treated, but in the case of a patient with tetralogy of Fallot, it is caused by a blood flow made turbulent by the defects in the ventricles and valves of the heart.
