Because the valve cannot prevent regurgitation, the efficiency of the heart will be reduced. This means that the heart has to pump harder to move blood, and is not able to pump as much blood as it should. If the right heart is pumping blood faster than the left heart can, then blood will build up in the circulatory vessels of the lungs, pulmonary vein and left atrium. This is a condition called pulmonary hypertension and can make it difficult for the patient to breathe and cause chest pain. Since the body is wonderful at adapting to adverse conditions, the heart will compensate for its inability to pump enough blood by increasing its stroke volume.
Stroke volume is the amount of blood the heart can pump in one cardiac cycle.
To increase stroke volume, the size of the ventricle must increase. This can cause fatigue, chest pain and other symptoms. There may be other underlying causes behind some of the above symptoms including, but not limited to, aortic valve disease, coronary artery atherosclerosis, disease of the valves in the right heart, pulmonary disease, etc. Mitral Value Prolapse is treated depending on how bad the condition is. As mentioned previously, most people with this condition do not require treatment.
