In mitral valve disease, the mitral valve, which is located between your left heart chambers (left atrium and left ventricle), doesn’t work properly
There are two types of mitral valve disease:
Mitral Valve Regurgitation:
the flaps (leaflets) of the mitral valve don’t close tightly, causing blood to leak backward into the left atrium of your heart.
Mitral valve stenosis:
the flaps of the mitral valve become thick or stiff, and they may fuse together.
Symptoms of mitral valve disease could include: Abnormal heart sound heart through a stethoscope, fatigue, shortness of breath, swelling of your ankles and feet, or irregular heartbeat.
