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.
A heart murmur is an extra or unusual sound heard during a heartbeat. Murmurs range from very faint to very loud. Sometimes they sound like a whooshing or swishing noise. Normal heartbeats make a lub-DUPP or lub-DUB sound. This is the sound of the heart valves closing as blood moves through the heart. Doctors can hear these sounds and heart murmurs using a stethoscope.
