Aortic valve stenosis and mitral valve dysplasia are heart diseases. Mitral facies refers to a distinctive facial appearance associated with mitral stenosis. Rheumatic fever can also cause chronic mitral and aortic regurgitation. Aortic stenosis and mitral stenosis are the most common examples. Signs of mitral and tricuspid regurgitation may be present. Surgery is curative of mitral valve regurgitation. Mitral and tricuspid defects are opposite. This loss of coaptation may lead to mitral and tricuspid regurgitation. There are some valvular heart diseases that affect the mitral valve. Cardiac causes like congestive heart failure and mitral stenosis should be ruled out. The first heart sound is made by the mitral and tricuspid heart valves closing. Both complications may lead to worsening of mitral regurgitation. An ostium secundum ASD accompanied by an acquired mitral valve stenosis is called Lutembacher's syndrome. Dysfunction of any of these portions of the mitral valve apparatus can cause regurgitation. The left atrial appendage can serve as an approach for mitral valve surgery.
