Heart diseases produce characteristic sounds which can be heard at the chest with a stethoscope. We want to understand the causes of these sounds.
In a normal heart, when the ventricle contracts, the aortic valve opens and blood gets pumped out. During this phase of the heart cycle the mitral valve stays shut. It stays shut because of cord-like tendons. If because of a disease or an accident the cords get damaged, then the mitral valve can prolapse when the ventricle contracts. This can lead to a honking sound called a mitral valve honk.
