||What Are Its Effects?
The abnormal mitral valve causes the left atrium to work harder than normal
in order to pump its supply of blood into the left ventricle. The result
is increased blood pressure in the left atrium and in the lungs, which send
oxygen-rich blood to the left atrium.
The symptoms of Mitral Stenosis may be absent or very slight for long periods. However, they may gradually or suddenly worsen. If the blockage of the valve becomes severe, the left atrium will be unable to do its job adequately, blood will back up into the lungs and body tissues, and heart failure may ensue.
The adverse symptoms that can be caused by Mitral Stenosis often appear at times of stress, such as during strenuous exertion, in conjunction with a fever (when the heart pumps more vigorously), or when one is experiencing powerful emotions, such as fear. These symptoms may include tiredness, lack of energy, difficulty breathing or shortness of breath, heart palpitations, flushed cheeks, and a persistent cough, sometimes producing blood.
