- Valvular stenosis and valvular regurgitation are the two types of heart valve problems.

Mitral valve stenosis occurs when a mitral valve is closed while it should be open during diastole. If a patient has mitral valve stenosis, the murmur is diastolic.Mitral Valve Stenosis
A mitral valve regurgitation occurs when a mitral valve is open, allowing backflow of blood while it should be closed, such as during systole. Therefore, a mitral valve regurgitation murmur is a systolic murmur. An example of stenosis and regurgitation involving the mitral valve.Mitral Valve Regurgitation
The aortic valve is situated between the left ventricle and the aorta. It should open during systole, allowing blood to flow out to the body. Diastole is the filling of the heart. Systole is the pumping of the heart.Aortic Valve Murmurs
Aortic valve stenosis occurs when an aortic valve is closed when it should be open. An aortic valve stenosis murmur is a systolic murmur.Aortic Valve Stenosis

Aortic valve regurgitation occurs when an aortic valve is open when it should be closed during diastole. The aortic valve regurgitation murmur is diastolic.Aortic Valve Regurgitation
The two main types of heart valve problems are valvular stenosis and valvular regurgitation. They typically happen in either the aortic or mitral valve. Depending on the valve and problem type, heart murmurs present in different areas of the patient.Summary
