Normal people, mitral regurgitation?

Mitral and tricuspid regurgitation usually does not occur in normal people.

Mitral and tricuspid valves are valves between atrium and ventricle, which are generally one-way open. Blood enters atrium through valves from ventricle. Valves will prevent blood regurgitation. Mitral and tricuspid regurgitation in normal people generally indicates heart valve insufficiency and related diseases.

Rheumatic heart disease, endocarditis, heart valve deformity, mitral valve prolapse and other factors may cause mitral and tricuspid regurgitation. If it continues to worsen, it may cause atrial fibrillation and heart failure.
