This short explainer from the American Heart Association introduces heart murmurs in under a minute. A heart murmur is the sound of blood whooshing or a valve clicking as blood moves between chambers, detected by a healthcare provider using a stethoscope. Many murmurs are innocent or benign and cause no harm. However, a murmur can also signal an underlying valve problem that may eventually need treatment — the two most common being stenosis (valve narrowing) and regurgitation (valve leaking).
Heart symptoms and treatment decisions should be evaluated by a qualified clinician, especially when symptoms are new, severe, or worsening.
