What are Valve Disorders?
A valve that is diseased or damaged can affect the blood flow through the heart. The two main types of valve problem are valve stenosis and valve regurgitation. Any of the valves can be affected by these disorders, but the aortic and mitral valves are the most commonly affected ones.
Valve stenosis is when the opening of the valve is narrowed so it cannot open fully, and there is a restriction in the blood flow.
Valve regurgitation is when the valve does not close properly and there is a backflow of blood through the valve.
How common are Valve Disorders?
There are various pre-existing conditions that can increase the risk of valve disorders. These include degenerative changes, rheumatic heart disease and some congenital heart problems.
What are the symptoms of Valve Disorders?
If the narrowness is severe, the heart has to pump harder to get the blood past the valve, and if the leakiness is severe the heart has to pump harder to pump back the backflow of blood, both of which puts a stain on the heart, causing symptoms.
Symptoms include shortness of breath, tiredness, dizziness or fainting, abnormal heart rhythms, swelling of tissues, and chest pain or angina.
How are Valve Disorders treated?
If the valve disorders are mild you may not need any regular treatment. Medication may be used if complications occur, and surgery to stretch, repair or replace the valve may be needed.
If you have not received treatment or advice, or suffered any symptoms in the past five years choose a moratorium product.
