Why shortness of breath can be a sign of mitral valve regurgitation
Why shortness of breath can be a sign of mitral valve regurgitation: Mitral valve regurgitation is a heart disease where blood flows backwards through the mitral valve. The mitral valve is a one-way valve that allows blood to move from the atria to the ventricles. If the valve allows bidirectional flow of blood, it leads to a number of complications. One such complication of mitral regurgitation is shortness of breath. Following are the causes of breathing difficulties due to this type of disease.
A mixture of oxygenated and deoxygenated blood
As mentioned earlier, the mitral valve allows the unidirectional flow of blood from the atria to the ventricles. These two chambers differentiate between oxygenated and deoxygenated blood. Oxygenated blood is collected from the lungs and delivered to the heart. From the heart it is transported to different parts of the body. Deoxygenated blood is collected from the muscles of various organs and delivered to the heart. This oxygenated and deoxygenated blood is collected in different chambers of the heart separated by these valves. If this valve allows bidirectional flow of blood, this will lead to mixing of the two types of blood. As a result, less oxygen will be carried to the muscles. As the oxygen demand of the muscles increases, the patient will need to breathe in more oxygen, resulting in shortness of breath.
Decrease in blood pressure to deliver oxygen to various organs
The heart is the primary organ that pumps oxygenated blood to various parts of the body. Part of this blood pressure is due to the unidirectional flow of blood maintained by the heart. However, if blood flows in two directions between the chambers of the heart, this will lower blood pressure, resulting in blood taking longer to reach distant muscles. The oxygen demand of the muscles is not met, resulting in the need for more oxygen to be taken in by the respiratory system. Such a condition leads to breathing problems.
Because mitral valve regurgitation reduces the transport of oxygen to various parts of the body, it is also associated with associated symptoms. The patient often feels tired and fatigued. Shortness of breath is pronounced when the patient is sleeping or metabolically active. It can lead to abnormal heartbeat.
If you feel that you are suffering from any of these symptoms, it could be a case of mitral valve regurgitation. If you visit a cardiologist once it will help.
